Pulse-enhanced two-photon interference with solid state quantum emitters

By Herbert F. Fotso from Recent Articles in Phys. Rev. B. Published on Sep 23, 2019.

Author(s): Herbert F. Fotso

The ability to entangle distant quantum nodes is essential for the construction of quantum networks and for quantum information processing. For solid-state quantum emitters used as qubits, it can be achieved by photon interference. When the emitter is subject to spectral diffusion, this process can ...

Growth of nematic susceptibility in the field-induced normal state of an iron-based superconductor revealed by elastoresistivity measurements in a 65 T pulsed magnet

By J. A. W. Straquadine, J. C. Palmstrom, P. Walmsley, A. T. Hristov, F. Weickert, F. F. Balakirev, M. Jaime, R. McDonald, and I. R. Fisher from Recent Articles in Phys. Rev. B. Published on Sep 23, 2019.

Author(s): J. A. W. Straquadine, J. C. Palmstrom, P. Walmsley, A. T. Hristov, F. Weickert, F. F. Balakirev, M. Jaime, R. McDonald, and I. R. Fisher

In iron-based superconductors, questions surrounding a putative nematic quantum critical point motivate study of the nematic susceptibility at low temperatures. By suppressing superconductivity with pulsed magnetic fields, this work extends the range of elastoresistivity measurements in nearly optimally doped Ba(CoxFe1x)2As2 an order of magnitude lower in temperature. The authors show that the nematic susceptibility in the field-induced normal state grows monotonically as temperature decreases. This is consistent with the existence of a nearby quantum critical point with nematic character.

Electronic band structure of a two-dimensional oxide quasicrystal

Author(s): Cheng-Tien Chiang, Martin Ellguth, Florian O. Schumann, Christian Tusche, Richard Kraska, Stefan Förster, and Wolf Widdra

Since the discovery of quasicrystals, the study of their electronic structure has been a challenging topic due to the absence of translational symmetry. Here, the valence bands of a novel two-dimensional ultrathin BaTiO3-derived oxide quasicrystal are determined by momentum-resolved photoelectron spectroscopy. The dispersion of the oxygen 2p bands and the occupation of the Ti 3d states are identified. They bridge the knowledge deriving from free-electron-like wave functions in bulk quasicrystals to that of the more localized electrons in confined dimensions.

Fractonic matter in symmetry-enriched $U(1)$ gauge theory

By Dominic J. Williamson, Zhen Bi, and Meng Cheng from Recent Articles in Phys. Rev. B. Published on Sep 23, 2019.

Author(s): Dominic J. Williamson, Zhen Bi, and Meng Cheng

This study reveals the relation between symmetry restrictions on the mobility of quasiparticles and symmetry-enriched topological order, where the actions of translation and global symmetries on quasiparticle excitations do not commute. The approach is demonstrably fruitful as one can systematically classify U(1) gauge theories enriched by translation and certain global symmetry and identify new examples of fractonic matter. It is conjectured that all such theories can be constructed by gauging layered symmetry-protected topological phases.

Unidirectional propagation of spin waves is key to the realization of magnonic logic devices. Here, the authors experimentally demonstrate excitations of unidirectional exchange spin waves by a nanoscale magnetic grating fabricated on an ultrathin yttrium iron garnet film. The authors explain and model the nearly perfect unidirectional excitation by the chirality of the magnetodipolar interactions. Reversal of the magnetic configurations changes the direction of the exchange spin waves. Such results raise the prospect of a chiral magnonic logic without the need for fragile surface states.

Symmetry fractionalization, defects, and gauging of topological phases

Author(s): Maissam Barkeshli, Parsa Bonderson, Meng Cheng, and Zhenghan Wang

This paper develops a comprehensive theory of symmetry fractionalization together with the properties of symmetry defects in topologically ordered phases of matter in two spatial dimensions. To do this, the authors also introduce the full set of data, consistency conditions, and equivalences for a mathematical theory, known as a G-crossed braided tensor category, that characterizes the algebraic braiding and fusion properties of symmetry defects. This theoretical framework can completely characterize and classify symmetry-enriched topological phases of matter in the presence of arbitrarily strong interactions in quantum many-body systems in two spatial dimensions.

Although great efforts have been expended on the deconfined quantum critical point (DQCP) for 2D systems, ambiguities are still not completely clarified. Here, the authors focus on a recently proposed 1D incarnation of DQCP in a spin-½ chain. Using the variational matrix product state, a continuous transition between a valence-bond solid phase and a ferromagnetic phase is discovered. Two emergent O(2) symmetries together with the associated conserved current operators are revealed and in perfect agreement with the controlled field theory predictions.

Author(s): Alexander Farutin, Jocelyn Étienne, Chaouqi Misbah, and Pierre Recho

There is increasing evidence that mammalian cells not only crawl on substrates but can also swim in fluids. To elucidate the mechanisms of the onset of motility of cells in suspension, a model which couples actin and myosin kinetics to fluid flow is proposed and solved for a spherical shape. The swi...

Resource Theory of Coherence Based on Positive-Operator-Valued Measures

By Felix Bischof, Hermann Kampermann, and Dagmar Bruß from Recent Articles in Phys. Rev. Lett.. Published on Sep 12, 2019.

Author(s): Felix Bischof, Hermann Kampermann, and Dagmar Bruß

Quantum coherence is a fundamental feature of quantum mechanics and an underlying requirement for most quantum information tasks. In the resource theory of coherence, incoherent states are diagonal with respect to a fixed orthonormal basis; i.e., they can be seen as arising from a von Neumann measur...
