      Abstract: Author(s): Tanish Satoor, Aurélien Fabre, Jean-Baptiste Bouhiron, Alexandre Evrard, Raphael Lopes, and Sylvain Nascimbene
      Quantum spins of mesoscopic size are a well-studied playground for engineering nonclassical states. If the spin represents the collective state of an ensemble of qubits, its nonclassical behavior is linked to entanglement between the qubits. In this paper, we report on an experimental study of entan...

      Abstract: Author(s): Sabyasachi Tiwari, Joren Vanherck, Maarten L. Van de Put, William G. Vandenberghe, and Bart Sorée
      We compare three first-principles methods of calculating the Curie temperature in two-dimensional (2D) ferromagnetic materials (FM), modeled using the Heisenberg model, and propose a simple formula for estimating the Curie temperature with high accuracy that works for all common 2D lattice types. Fi...

      In a continuous-variable optical system, the Gottesman-Kitaev-Preskill (GKP) qubit is a promising candidate for fault-tolerant quantum computation. To implement non-Clifford operations on GKP qubits, non-Gaussian operations are required. In this context, the implementation of a cubic phase gate by c...

      We derive nonlinear wave equations describing the propagation of slowly varying wave packets formed by topological valley-Hall edge states. We show that edge pulses break up even in the absence of spatial dispersion due to nonlinear self-steepening. Self-steepening leads to the previously unattended...

That is, a correlated photon pair must have an inherent time delay between its constituent photons. Th...

      Abstract: Author(s): Ross Shillito, Jonathan A. Gross, Agustin Di Paolo, Élie Genois, and Alexandre Blais
      The controls enacting logical operations on quantum systems are described by time-dependent Hamiltonians that often include rapid oscillations. In order to accurately capture the resulting time dynamics in numerical simulations, a very small integration time step is required, which can severely impa...

      Abstract: Author(s): Martin J. Falk, Vahid Alizadehyazdi, Heinrich Jaeger, and Arvind Murugan
      The study of active matter has revealed novel non-equilibrium collective behaviors, illustrating their potential as a new materials platform. However, most work treat active matter as unregulated systems with uniform microscopic energy input, which we refer to as activity. In contrast, functionality...
