## 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 ...

By suppressing superconductivity with pulsed magnetic fields, this work extends the range of elastoresistivity measurements in nearly optimally doped Ba(Co${}_{x}$Fe${}_{1-x}$)${}_{2}$As${}_{2}$ 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.

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.

The dispersion of the oxygen 2$p$ bands and the occupation of the Ti 3$d$ states are identified.

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. [Phys. Rev.

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

By Maissam Barkeshli, Parsa Bonderson, Meng Cheng, and Zhenghan Wang from Recent Articles in Phys. Rev. B. Published on Sep 20, 2019.

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.

We experimentally study the spin dynamics in a gadolinium iron garnet single crystal using broadband ferromagnetic resonance. Close to the ferrimagnetic compensation temperature, we observe ultrastrong coupling of clockwise and counterclockwise magnon modes. The magnon-magnon coupling strength reach...

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...
