  • Finite Type Modules and Bethe Ansatz Equations
    • Authors: Boris Feigin; Michio Jimbo; Tetsuji Miwa; Eugene Mukhin
      Pages: 2543 - 2579
      Abstract: Abstract We introduce and study a category \(\mathcal {O}^\mathrm{fin}_{\mathfrak {b}}\) of modules of the Borel subalgebra \(U_q\mathfrak {b}\) of a quantum affine algebra \(U_q\mathfrak {g}\) , where the commutative algebra of Drinfeld generators \(h_{i,r}\) , corresponding to Cartan currents, has finitely many characteristic values. This category is a natural extension of the category of finite-dimensional \(U_q\mathfrak {g}\) modules. In particular, we classify the irreducible objects, discuss their properties, and describe the combinatorics of the q-characters. We study transfer matrices corresponding to modules in \(\mathcal {O}^\mathrm{fin}_{\mathfrak {b}}\) . Among them, we find the Baxter \(Q_i\) operators and \(T_i\) operators satisfying relations of the form \(T_iQ_i=\prod _j Q_j+ \prod _k Q_k\) . We show that these operators are polynomials of the spectral parameter after a suitable normalization. This allows us to prove the Bethe ansatz equations for the zeroes of the eigenvalues of the \(Q_i\) operators acting in an arbitrary finite-dimensional representation of \(U_q\mathfrak {g}\) .

  • Painlevé 2 Equation with Arbitrary Monodromy Parameter, Topological
           Recursion and Determinantal Formulas
    • Authors: Kohei Iwaki; Olivier Marchal
      Pages: 2581 - 2620
      Abstract: Abstract The goal of this article is to prove that the determinantal formulas of the Painlevé 2 system identify with the correlation functions computed from the topological recursion on their spectral curve for an arbitrary nonzero monodromy parameter. The result is established for a WKB expansion of two different Lax pairs associated with the Painlevé 2 system, namely the Jimbo–Miwa Lax pair and the Harnad–Tracy–Widom Lax pair, where a small parameter \(\hbar \) is introduced by a proper rescaling. The proof is based on showing that these systems satisfy the topological type property introduced in Bergère et al. (Ann Henri Poincaré 16:2713, 2015), Bergère and Eynard (arxiv:0901.3273, 2009). In the process, we explain why the insertion operator method traditionally used to prove the topological type property is currently incomplete and we propose new methods to bypass the issue. Our work generalizes similar results obtained from random matrix theory in the special case of vanishing monodromies (Borot and Eynard in arXiv:1011.1418, 2010; arXiv:1012.2752, 2010). Explicit computations up to \(g=3\) are provided along the paper as an illustration of the results. Eventually, taking the time parameter t to infinity we observe that the symplectic invariants \(F^{(g)}\) of the Jimbo–Miwa and Harnad–Tracy–Widom spectral curves converge to the Euler characteristic of moduli space of genus g Riemann surfaces.

  • Inverse Scattering on the Half-Line for a First-Order System with a
           General Boundary Condition
    • Authors: Mansur I. Ismailov
      Pages: 2621 - 2639
      Abstract: Abstract The inverse scattering problem of recovering the matrix coefficient of a first-order system on the half-line from its scattering matrix is considered. In the case of a triangular structure of the matrix coefficient, this system has a Volterra-type integral transformation operator at infinity. Such a transformation operator allows to determine the scattering matrix on the half-line via the matrix Riemann–Hilbert factorization in the case, where the contour is real line, the normalization is canonical, and all the partial indices are zero. The ISP on the half-line is solved by reducing it to an ISP on the whole line for the considered system with the coefficients that are extended to the whole line by zero.

  • Strings in Singular Space-Times and Their Universal Gauge Theory
    • Authors: Athanasios Chatzistavrakidis; Andreas Deser; Larisa Jonke; Thomas Strobl
      Pages: 2641 - 2692
      Abstract: Abstract We study the propagation of bosonic strings in singular target space-times. For describing this, we assume this target space to be the quotient of a smooth manifold M by a singular foliation \({{\mathcal {F}}}\) on it. Using the technical tool of a gauge theory, we propose a smooth functional for this scenario, such that the propagation is assured to lie in the singular target on-shell, i.e., only after taking into account the gauge-invariant content of the theory. One of the main new aspects of our approach is that we do not limit \({{\mathcal {F}}}\) to be generated by a group action. We will show that, whenever it exists, the above gauging is effectuated by a single geometrical and universal gauge theory, whose target space is the generalized tangent bundle \(TM\oplus T^*M\) .

  • Global Anomalies on Lorentzian Space-Times

      Abstract: Abstract We formulate an algebraic criterion for the presence of global anomalies on globally hyperbolic space-times in the framework of locally covariant field theory. We discuss some consequences and check that it reproduces the well-known global SU(2) anomaly in four space-time dimensions.

      Abstract: Abstract We consider the massive Klein–Gordon equation on a class of asymptotically static spacetimes (in the long-range sense) with Cauchy surface of bounded geometry. We prove the existence and Hadamard property of the in and out states constructed by scattering theory methods.

  • Existence of Quasinormal Modes for Kerr–AdS Black Holes
    • Authors: Oran Gannot
      Pages: 2757 - 2788
      Abstract: Abstract This paper establishes the existence of quasinormal frequencies converging exponentially to the real axis for the Klein–Gordon equation on a Kerr–AdS spacetime when Dirichlet boundary conditions are imposed at the conformal boundary. The proof is adapted from results in Euclidean scattering about the existence of scattering poles generated by time-periodic approximate solutions to the wave equation.

  • Inequalities Between Size, Mass, Angular Momentum, and Charge for
           Axisymmetric Bodies and the Formation of Trapped Surfaces
    • Authors: Marcus Khuri; Naqing Xie
      Pages: 2815 - 2830
      Abstract: Abstract We establish inequalities relating the size of a material body to its mass, angular momentum, and charge, within the context of axisymmetric initial data sets for the Einstein equations. These inequalities hold in general without the assumption of the maximal condition and use a notion of size which is easily computable. Moreover, these results give rise to black hole existence criteria which are meaningful even in the time-symmetric case, and also include certain boundary effects.

  • On the $$C^*$$ C ∗ -Algebraic Approach to Topological Phases for
    • Authors: Johannes Kellendonk
      Pages: 2251 - 2300
      Abstract: Abstract The notion of a topological phase of an insulator is based on the concept of homotopy between Hamiltonians. It therefore depends on the choice of a topological space to which the Hamiltonians belong. We advocate that this space should be the \(C^*\) -algebra of observables. We relate the symmetries of insulators to graded real structures on the observable algebra and classify the topological phases using van Daele’s formulation of K-theory. This is related but not identical to Thiang’s recent approach to classify topological phases by K-groups in Karoubi’s formulation.

  • Small Cocycles, Fine Torus Fibrations, and a $$\varvec{\mathbb {Z}^{2}}$$
           Z 2 Subshift with Neither
    • Authors: Alex Clark; Lorenzo Sadun
      Pages: 2301 - 2326
      Abstract: Abstract Following an earlier similar conjecture of Kellendonk and Putnam, Giordano, Putnam, and Skau conjectured that all minimal, free \(\mathbb {Z}^d\) actions on Cantor sets admit “small cocycles.” These represent classes in \(H^1\) that are mapped to small vectors in \(\mathbb {R}^d\) by the Ruelle–Sullivan (RS) map. We show that there exist \(\mathbb {Z}^2\) actions where no such small cocycles exist, and where the image of \(H^1\) under RS is \(\mathbb {Z}^2\) . Our methods involve tiling spaces and shape deformations, and along the way we prove a relation between the image of RS and the set of “virtual eigenvalues,” i.e., elements of \(\mathbb {R}^d\) that become topological eigenvalues of the tiling flow after an arbitrarily small change in the shapes and sizes of the tiles.

  • Characterization of the Metal–Insulator Transport Transition for the
           Two-Particle Anderson Model
    • Authors: Abel Klein; Son T. Nguyen; Constanza Rojas-Molina
      Pages: 2327 - 2365
      Abstract: Abstract We extend to the two-particle Anderson model the characterization of the metal–insulator transport transition obtained in the one-particle setting by Germinet and Klein. We show that, for any fixed number of particles, the slow spreading of wave packets in time implies the initial estimate of a modified version of the bootstrap multiscale analysis. In this new version, operators are restricted to boxes defined with respect to the pseudo-distance in which we have the slow spreading. At the bottom of the spectrum, within the regime of one-particle dynamical localization, we show that this modified multiscale analysis yields dynamical localization for the two-particle Anderson model, allowing us to obtain a characterization of the metal–insulator transport transition for the two-particle Anderson model at the bottom of the spectrum.

  • On Landau–Zener Transitions for Dephasing Lindbladians
    • Authors: Martin Fraas; Lisa Hänggli
      Pages: 2447 - 2465
      Abstract: Abstract We consider a driven open system whose evolution is described by a Lindbladian. The Lindbladian is assumed to be dephasing and its Hamiltonian part to be given by the Landau–Zener Hamiltonian. We derive a formula for the transition probability which, unlike previous results, extends the Landau–Zener formula to open systems.

  • Generalized Log-Majorization and Multivariate Trace Inequalities
    • Authors: Fumio Hiai; Robert König; Marco Tomamichel
      Pages: 2499 - 2521
      Abstract: Abstract We show that recent multivariate generalizations of the Araki–Lieb–Thirring inequality and the Golden–Thompson inequality (Sutter et al. in Commun Math Phys, 2016. doi:10.1007/s00220-016-2778-5) for Schatten norms hold more generally for all unitarily invariant norms and certain variations thereof. The main technical contribution is a generalization of the concept of log-majorization which allows us to treat majorization with regard to logarithmic integral averages of vectors of singular values.

  • Final State Problem for Systems of Cubic Nonlinear Schrödinger
           Equations in One Dimension
    • Authors: Kota Uriya
      Pages: 2523 - 2542
      Abstract: Abstract In this paper, we are concerned with the asymptotic behavior of the solution to systems of cubic nonlinear Schrödinger equations in one dimension. It is known that mass transition phenomenon occurs for a system of quadratic nonlinear Schrödinger equations in two dimensions under the mass resonance condition. We show that mass transition phenomenon also occurs for systems with cubic nonlinearity under the corresponding mass resonance conditions.

  • Some Remarks on the $$C^0$$ C 0 -(In)Extendibility of Spacetimes
    • Authors: Gregory J. Galloway; Eric Ling
      Abstract: Abstract The existence, established over the past number of years and supporting earlier work of Ori (Phys Rev Lett 68(14):2117–2120, 1992), of physically relevant black hole spacetimes that admit \(C^0\) metric extensions beyond the future Cauchy horizon, while being \(C^2\) -inextendible, has focused attention on fundamental issues concerning the strong cosmic censorship conjecture. These issues were recently discussed in the work of Sbierski (The \({C}^0\) -inextendibility of the Schwarzschild spacetime and the spacelike diameter in Lorentzian geometry. arXiv:1507.00601v2, (to appear in J. Diff. Geom.), 2015), in which he established the (nonobvious) fact that the Schwarzschild solution in global Kruskal–Szekeres coordinates is \(C^0\) -inextendible. In this paper, we review aspects of Sbierski’s methodology in a general context and use similar techniques, along with some new observations, to consider the \(C^0\) -inextendibility of open FLRW cosmological models. We find that a certain special class of open FLRW spacetimes, which we have dubbed ‘Milne-like,’ actually admits \(C^0\) extensions through the big bang. For spacetimes that are not Milne-like, we prove some inextendibility results within the class of spherically symmetric spacetimes.

  • Quantum Graphs which Optimize the Spectral Gap
    • Authors: Ram Band; Guillaume Lévy
      Abstract: Abstract A finite discrete graph is turned into a quantum (metric) graph once a finite length is assigned to each edge and the one-dimensional Laplacian is taken to be the operator. We study the dependence of the spectral gap (the first positive Laplacian eigenvalue) on the choice of edge lengths. In particular, starting from a certain discrete graph, we seek the quantum graph for which an optimal (either maximal or minimal) spectral gap is obtained. We fully solve the minimization problem for all graphs. We develop tools for investigating the maximization problem and solve it for some families of graphs.

  • Central Limit Theorem and Large Deviation Principle for Continuous Time
           Open Quantum Walks
    • Authors: Hugo Bringuier
      Abstract: Abstract Open quantum walks (OQWs), originally introduced in Attal et al. (J Stat Phys 147(4):832–852, 2012), are quantum generalizations of classical Markov chains. Recently, natural continuous time models of OQW have been developed in Pellegrini (J Stat Phys 154(3):838–865, 2014). These models, called continuous time open quantum walks (CTOQWs), appear as natural continuous time limits of discrete time OQWs. In particular, they are quantum extensions of continuous time Markov chains. This article is devoted to the study of homogeneous CTOQW on \(\mathbb {Z}^d\) . We focus namely on their associated quantum trajectories which allow us to prove a central limit theorem for the “position” of the walker as well as a large deviation principle.

  • On Scattering for Small Data of $$\varvec{2 + 1}$$ 2 + 1 -Dimensional
           Equivariant Einstein-Wave Map System
    • Authors: Benjamin Dodson; Nishanth Gudapati
      Abstract: Abstract We consider the Cauchy problem of \(2+1\) equivariant wave maps coupled to Einstein’s equations of general relativity and prove that two separate (nonlinear) subclasses of the system disperse to their corresponding linearized equations in the large. Global asymptotic behavior of \(2+1\) Einstein-wave map system is relevant because the system occurs naturally in \(3+1\) vacuum Einstein’s equations.

  • Area Operator in Loop Quantum Gravity
    • Authors: Adrian P. C. Lim
      Abstract: Abstract A hyperlink is a finite set of non-intersecting simple closed curves in \(\mathbb {R} \times \mathbb {R}^3\) . Let S be an orientable surface in \(\mathbb {R}^3\) . The dynamical variables in general relativity are the vierbein e and a \(\mathfrak {su}(2)\times \mathfrak {su}(2)\) -valued connection \(\omega \) . Together with Minkowski metric, e will define a metric g on the manifold. Denote \(A_S(e)\) as the area of S, for a given choice of e. The Einstein–Hilbert action \(S(e,\omega )\) is defined on e and \(\omega \) . We will quantize the area of the surface S by integrating \(A_S(e)\) against a holonomy operator of a hyperlink L, disjoint from S, and the exponential of the Einstein–Hilbert action, over the space of vierbeins e and \(\mathfrak {su}(2)\times \mathfrak {su}(2)\) -valued connections \(\omega \) . Using our earlier work done on Chern–Simons path integrals in \(\mathbb {R}^3\) , we will write this infinite dimensional path integral as the limit of a sequence of Chern–Simons integrals. Our main result shows that the area operator can be computed from a link-surface diagram between L and S. By assigning an irreducible representation of \(\mathfrak {su}(2)\times \mathfrak {su}(2)\) to each component of L, the area operator gives the total net momentum impact on the surface S.
