  • Polaronic Transport Induced by Competing Interfacial Magnetic Order in a
           La0.7Ca0.3MnO3/BiFeO3 Heterostructure

      Abstract: Author(s): Y. M. Sheu, S. A. Trugman, L. Yan, J. Qi, Q. X. Jia, A. J. Taylor, and R. P. Prasankumar Composite thin films composed of ferromagnetic metallic manganite La0.7Ca0.3MnO3 (LCMO) and multiferroic BiFeO3 (BFO) host a novel magnetotransport phenomenon at the interface that can be controlled by switching the ferroelectric polarization in BFO. A new experiment reveals that suppression by BFO of the polaronic coupling between electrons and Mn ions in LCMO frees the electron and enables the transport. Creative Commons [Phys. Rev.

  • Magnetic Localized Surface Plasmons

      Abstract: Author(s): Paloma A. Huidobro, Xiaopeng Shen, J. Cuerda, Esteban Moreno, L. Martin-Moreno, F. J. Garcia-Vidal, Tie Jun Cui, and J. B. Pendry Surface plasmons, electromagnetic fields generated by the charge oscillations at the surface of a light-illuminated metallic nanoparticle, are typically described in terms of effective electric dipoles and their dynamics. Scientists discover that adding periodic grooves to the surface of subwavelength metallic disks creates localized surface plasmons of magnetic character in addition to the typical electric ones.

      Abstract: Author(s): C. Arnold, V. Loo, A. Lemaître, I. Sagnes, O. Krebs, P. Voisin, P. Senellart, and L. Lanco Highly sensitive, high-speed control and detection of light–quantum-state interactions in nanoscale quantum devices such as quantum dots is key in quantum technology. Scientists achieve real-time detection of single-charge jumps in a quantum dot by amplifying its interaction with photons using a micropillar optical cavity and measuring the interaction with a high-speed technique.

Paulus, Atsushi Iwasaki, Andrius Baltuška, Kaoru Yamanouchi, and Markus Kitzler Removing electrons in a polyatomic molecule from their orbitals can split the molecule into two ionic fragments. The precise fragmentation pathway taken depends on the molecular orbitals. Scientists show that selective fragmentation can be achieved by controlling the intensity and duration of the laser pulses used to remove the electrons.

      Abstract: Author(s): Helmut G. Katzgraber, Firas Hamze, and Ruben S. Andrist Recent benchmarking of the computational speedup of quantum “annealing” machines of the D-Wave-2 type shows that they do not perform faster than a standard desktop computer.

      Abstract: Author(s): Uwe C.

  • Fluctuations of Imbalanced Fermionic Superfluids in Two Dimensions Induce
           Continuous Quantum Phase Transitions and Non-Fermi-Liquid Behavior

    • Authors: Philipp Strack; Pawel Jakubczyk
      First page: 021012
      Abstract: Author(s): Philipp Strack and Pawel Jakubczyk An ultracold mixture of two different species of fermionic atoms can turn into a quantum coherent “superfluid” at certain mixing ratios as the fermions overcome their natural repulsion to pair up. Tuning the mixing can destroy the superfluid. A theoretical study shows that the breakdown of the superfluid corresponds to a new type of quantum critical point that is experimentally accessible.

      Abstract: Author(s): Sebastian Deffner, Christopher Jarzynski, and Adolfo del Campo A natural nonequilibrium process that takes a system from one equilibrium state to another in a short time always involves dissipation. But, it’s actually possible in quantum control to design and implement dissipationless “shortcuts” for quantum systems. Scientists add a few concrete practical tools for achieving this goal.

  • Transition-Metal Pentatelluride ZrTe5 and HfTe5: A Paradigm for Large-Gap
           Quantum Spin Hall Insulators

    • Authors: Hongming Weng; Xi Dai, Zhong Fang
      First page: 011002
      Abstract: Author(s): Hongming Weng, Xi Dai, and Zhong FangQuantum spin Hall (QSH) insulators, with their insulating interior and conducting edges, have great potential for technological applications. But, scarcity and difficulty in fabrication are major obstacles to their wide applications. Theorists now predict that single sheets that can be exfoliated from two well-known layered thermoelectric compounds, ZrTe5 and HfTe5, are the most promising QSH insulator candidates to date.Creative Commons [Phys.

  • Orientation-Dependent Handedness and Chiral Design

      Abstract: Author(s): Efi Efrati and William T. M. IrvineThe handedness of an object has always been a binary concept: either left handed or right handed. Scientists now show that quantifying handedness as direction-dependent properties actually makes fundamental physical sense and can guide both our understanding of known handedness phenomena and design of materials with novel handed-response properties.Creative Commons [Phys.

Now scientists have found a way to dramatically reduce it to a technically tractable form and demonstrate the power of the reduction with findings of new “chimera” states in populations of pulse-coupled oscillators.

      Abstract: Author(s): Tomislav Stankovski, Peter V. E. McClintock, and Aneta Stefanovska Secure encryption is essential in today’s world, and to beat illicit decryption, evermore secure schemes are needed. Inspired by cardiorespiratory coupling, a new scheme, radically different in concept from the existing encryption approaches, uses the coupling functions between two dynamical systems such as electronic oscillators to enable secure communications.

  • Demonstration of Long-Lived High-Power Optical Waveguides in Air

    • Authors: N. Jhajj; E. W. Rosenthal, R. Birnbaum, J. K. Wahlstrand, H. M. Milchberg

      Abstract: Author(s): N. Jhajj, E. W. Rosenthal, R. Birnbaum, J. K. Wahlstrand, and H. M. Milchberg Laser filaments are a promising means of transporting light energy over long distances, but they can only carry an average power of a few watts, thus limiting certain applications. Experiments now overcome this limitation by demonstrating that the thermal wake of a bundle of filaments provides a long-lived air waveguide that can channel laser beams with an extremely high average power.

  • Aging Renewal Theory and Application to Random Walks

    • Authors: Johannes H. P. Schulz; Eli Barkai, Ralf Metzler
      First page: 011028
      Abstract: Author(s): Johannes H. P. Schulz, Eli Barkai, and Ralf Metzler A normal renewal process is a sequence of independent events with the between-event time following the Poisson distribution. More complex renewal processes can “age,” characterized by non-Poissonian waiting-time distributions. A new theoretical approach dissects such aging renewal processes and offers many new insights, including how measurements on these processes should be unambiguously interpreted.

      Abstract: Author(s): Andrew N. Jordan, Julián Martínez-Rincón, and John C.

      Abstract: Author(s): Shelby Kimmel, Marcus P. da Silva, Colm A. Ryan, Blake R. Johnson, and Thomas Ohki Quantum processing tomography typically reconstructs an unknown quantum dynamical operation by measuring its effects on known states of a quantum device. Taking a different approach of comparing the operation of interest to a set of finite and easily implementable reference operations, a new method can reconstruct any quantum operation reliably.

      Abstract: Author(s): James R.

      Abstract: Author(s): David Pekker, Gil Refael, Ehud Altman, Eugene Demler, and Vadim Oganesyan Conventional phase transitions are usually characterized by a change in a fundamental thermodynamic observable, e.g., in density when liquid changes to vapor. A theoretical study of a one-dimensional disordered quantum spin chain reveals a new class of quantum phase transitions that leave no such signatures and pins down their origin.

      Abstract: Author(s): David Breuer, Marc Timme, and Raoul-Martin Memmesheimer Each dendrite in a biological neuron has long been thought to process the multiple inputs it receives in a simple additive fashion. Recent experiments, however, have demonstrated occurrences of nonadditive dendritic input processing.

      Abstract: Author(s): Arnaud Mussot, Alexandre Kudlinski, Maxime Droques, Pascal Szriftgiser, and Nail Akhmediev The celebrated Fermi-Pasta-Ulam recurrence phenomenon in nonlinear dynamics was first demonstrated experimentally in optical fibers 50 years after its theoretical discovery. But it was expected to be suppressed when the so-called third-third-order dispersion (TOD) became relevant. A new optical-fiber experiment shows that it not only survives in the presence of TOD, but disappears and reappears several times as the optical pump frequency is varied. Creative Commons [Phys. Rev.

      Abstract: Author(s): Bryan Nelsen, Gangqiang Liu, Mark Steger, David W. Snoke, Ryan Balili, Ken West, and Loren PfeifferExciton polaritons are essentially photons “dressed” by and interacting via their interaction with excitons in a semiconductor. As bosons, they exhibit Bose-Einstein condensation, in which they self-organize into a coherent state. Scientists have now extended their lifetime from 10 to 100 picoseconds and have observed a number of dramatic new effects, including a new and dynamic coherent state of spatially localized polaritons at high densities.Creative Commons [Phys.

      Abstract: Author(s): Lukasz Fidkowski, Xie Chen, and Ashvin VishwanathThe surface electronic structure of a three-dimensional topological superconductor is characterized by a Majorana cone—Majorana-fermion-like electronic excitations whose energies form a gapless continuum, rendering the surface conducting. It was believed that a gap in that electronic structure could only be created if time-reversal symmetry were broken. Theorists now show that, in the presence of strong electronic interaction, “gapping” and time-reversal symmetry can coexist if the surface has a special type of electronic excitations that are “anyons.”Creative Commons [Phys.

      Abstract: Author(s): Torsten Karzig, Gil Refael, and Felix von OppenRealization of Majorana fermions in solid-state systems offers a promising candidate for qubits in fault-tolerant quantum computing. How fast such qubits can be manipulated without loss in their quantum coherence motivates the need to understand the dynamics of solid-state Majorana fermions. Scientists discover that the dynamics is actually described by an effective variation of the original Dirac equation for the simpler relativistic free Majorana fermions and establish the speed limit for basic qubit manipulation.Creative Commons [Phys.

      Abstract: Author(s): Mykhaylo Evstigneev and Peter ReimannRecent experiments on friction between a moving atomic-scale tip and a smooth surface have shown that the friction has a nonmonotonic dependence on temperature and decreases with the tip’s velocity. No single theoretical model provides consistent rationalizations of all these experimental data. A new theory based on the notion of “contact aging”—a thermally activated process of the tip-surface contact strengthening—correctly predicts all these recent results.Creative Commons [Phys. Rev.

      Abstract: Author(s): Attila Szolnoki and Matjaž PercWhy do humans cooperate with other unrelated humans? Correlated use of both a “reward” and a “punishment” strategy has been thought to be an evolutionary force underlying our predisposition for cooperation: if others are kind to us, we are kind to them; if they are exploitive, we may stop cooperating or tend to punish them. Recent human experiments show, however, that individuals mostly use one strategy or the other, rarely both. Now, statistical physical simulations of an evolutionary game model lend significant support to these findings.Creative Commons [Phys. Rev. X 3, 041021] Published Wed Nov 27, 2013

Making them interact with each other in a controlled and scalable way even when they are separated over long distances is the next step. A new proposal shows that this goal can be achieved by coupling the spin qubits to a common ferromagnet and exploiting the fast traveling magnons in the ferromagnet as the agent mediating long-range qubit-qubit interactions.Creative Commons [Phys.

By inserting colloid particles—which behave as defects—into layered (smectic) liquid crystals to control molecular alignment, scientists develop a new way of generating and manipulating specific optical “flower textures” that may see applications.[Phys.

      Abstract: Author(s): Shuxiang Wu, Xin Luo, Stuart Turner, Haiyang Peng, Weinan Lin, Junfeng Ding, Adrian David, Biao Wang, Gustaaf Van Tendeloo, Junling Wang, and Tom WuMany commonly used electrical resistive switching devices are based on films of metal-oxide-metal “sandwiches.” Now scientists have observed ultrafast and reversible resistive switching in a thin-film device composed of a metallic platinum layer and two ultrathin layers of insulating oxides, LaAlO3 and SrTiO3, and revealed its origin in the oxides’ charge-carrying oxygen vacancies.Creative Commons [Phys.

      Abstract: Author(s): Jun-ichi Yoshikawa, Kenzo Makino, Shintaro Kurata, Peter van Loock, and Akira FurusawaNonclassical quantum states—those with no correspondence to classical states—can be characterized by a negative Wigner function and are vital to quantum-information processing. A new all-optical scheme achieves, for the first time, creation, storage, and on-demand release of highly nonclassical photonic states by using two coupled optical cavities, one for creation and storage, and the other for dynamical tuning of the release.Creative Commons [Phys.

      Abstract: Author(s): M. Trepanier, Daimeng Zhang, Oleg Mukhanov, and Steven M. AnlageA radio receiver that can tune to and digitize millions of frequencies per second, even if the signals are very weak, requires isolating the desired signal from stronger, unwanted noise. Scientists demonstrate a new kind of metamaterial, built with individual radio-frequency superconducting quantum-interference devices (rf SQUIDs), that allows such fast and long-range tuning by exploiting the large tunability of the nonlinear effective inductance of the Josephson junction in each SQUID.Creative Commons [Phys.

      Abstract: Author(s): Philipp Ambichl, Konstantinos G. Makris, Li Ge, Yidong Chong, A. Douglas Stone, and Stefan RotterCoupling a light-amplifying gain material with a light-absorbing lossy material should, if their strengths are carefully balanced, result in a system with no net amplification or absorption. However, this overall symmetry can spontaneously break down at a specific value of gain-loss strength. Surprisingly, scientists find that this “symmetry-breaking” point is extremely robust to modifications of the system by its optical boundary conditions and explain why.Creative Commons [Phys. Rev.

      First page: 041032
      Abstract: Author(s): B. Frisquet, B. Kibler, and G. MillotRecently nonlinear fiber optics has revealed the existence of “breathers,” a new form of solitons with periodic oscillations on a finite background. But, how do such breathers, when they appear at the same time, interact with each other? A new experiment demonstrates that two such breathers, when their initial shapes and propagations are properly controlled, can collide to make a new giant “rogue” wave.Creative Commons [Phys. Rev.

PothierWen two superconductors are connected through a weak link, discrete quasiparticle states localized at the link, called Andreev levels, are known to appear and leave their signatures in a “supercurrent” that flows through the link. Using microwave excitation and supercurrent measurements, scientists reveal the fundamental nature of the Andreev levels associated with a single-atom link.Creative Commons [Phys. Rev.
