Observation of topological edge states induced solely by non-Hermiticity in an acoustic crystal

He Gao, Haoran Xue, Qiang Wang, Zhongming Gu, Tuo Liu, Jie Zhu, and Baile Zhang

Phys. Rev. B 101, 180303(R) (2020) - Published 6 May, 2020

Most existing non-Hermitian topological systems derive their nontrivial topology from Hermitian factors. Here, the authors report on the experimental observation of acoustic topological edge states induced solely by non-Hermiticity. They show that non-Hermiticity is able to create a topological band gap from a gapless Hermitian system. The study offers the possibilities for actively steerable topological wave manipulations in applications ranging from acoustics to photonics.

Impact of nematicity on the relationship between antiferromagnetic fluctuations and superconductivity in FeSe0.91S0.09 under pressure

K. Rana, L. Xiang, P. Wiecki, R. A. Ribeiro, G. G. Lesseux, A. E. Böhmer, S. L. Bud'ko, P. C. Canfield, and Y. Furukawa

Phys. Rev. B 101, 180503(R) (2020) - Published 6 May, 2020

Relationships between nematicity, antiferromagnetism, and superconductivity have been a central theme for studies of iron-based superconductors. When these systems undergo a nematic transition, the fourfold rotational symmetry (C4) of antiferromagnetic correlations reduces to twofold (C2). The positive relationship between antiferromagnetic correlations and superconducting transition temperatures Tc is clearly seen in unconventional superconductors, but does it depend on the symmetry of the correlations? Here, the NMR study on sulfur-doped FeSe systems demonstrates that the relationship changes with the presence/absence of nematicity and also that C4-symmetric antiferromagnetic correlations are better in enhancing Tc than their C2-symmetric counterparts.

Very large Dzyaloshinskii-Moriya interaction in two-dimensional Janus manganese dichalcogenides and its application to realize skyrmion states

Jinghua Liang, Weiwei Wang, Haifeng Du, Ali Hallal, Karin Garcia, Mairbek Chshiev, Albert Fert, and Hongxin Yang

Phys. Rev. B 101, 184401 (2020) - Published 1 May, 2020

The intense recent research on skyrmions has focused on multilayers of classical magnetic materials, such as Co, CoFeB, or Fe. Here, the authors explore skyrmions in van der Waals bi-dimensional magnets, a new type of magnetic material in the broad family of 2D materials that contains graphene. Using ab initio and Monte Carlo calculations, they demonstrate that skyrmions should exist in the so-called Janus transition metal dichalcogenides. The temperature and magnetic field range for observation of skyrmions are also predicted, as a guide for experimental exploration.

Coupled quasimonopoles in chiral magnets

Phys. Rev. B 101, 184405 (2020) - Published 4 May, 2020

It is shown that in isotropic crystals of a chiral magnet, the dipole strings (DSs), representing coupled magnetic singularities (Bloch points) of the opposite sign, can emerge as stable states in geometrically confined samples as well as in the interior of bulk crystals. Here, the authors also report an intriguing effect of spontaneous nucleation of DSs at elevated temperatures near the paramagnetic phase transition, which may shed light on the nature of the A phase (anomalous phase) observed in bulk crystals of B20-type chiral magnets.

Quantum paraelectricity in the Kitaev quantum spin liquid candidates H3LiIr2O6 and D3LiIr2O6

K. Geirhos, P. Lunkenheimer, M. Blankenhorn, R. Claus, Y. Matsumoto, K. Kitagawa, T. Takayama, H. Takagi, I. Kézsmárki, and A. Loidl

Phys. Rev. B 101, 184410 (2020) - Published 8 May, 2020

H3LiIr2O6 shows no magnetic order down to lowest temperatures, raising hopes for a true Kitaev spin liquid. Its structure reveals H bonds between honeycomb layers and theory has proposed hydrogen disorder to affect the magnetic exchange. Using dielectric spectroscopy, the authors report here dipolar relaxations in H3LiIr2O6 and D3LiIr2O6, mirroring the dynamics of protons or deuterons within the double-well potentials of the H bonds. Under cooling, thermal activation crosses over into quantum tunneling, establishing a quantum paraelectric state with quasistatic disorder. This supports the realization of the long-pursued Kitaev spin liquid.

Long spin coherence times in the ground state and in an optically excited state of Er3+167:Y2SiO5 at zero magnetic field

Jelena V. Rakonjac, Yu-Hui Chen, Sebastian P. Horvath, and Jevon J. Longdell

Phys. Rev. B 101, 184430 (2020) - Published 27 May, 2020

Although superconducting qubits are one of the most promising systems for quantum information applications, a separate interface is required to allow for information distribution through optical links. Here, the authors investigate the suitability of 167Er3+:Y2SiO5 as a microwave-to-optical memory interface. This material holds considerable promise as it has an optical transition in the telecommunication band. The authors identify hyperfine transitions with long coherence times without an external magnetic field, which are suitable for interfacing with superconducting qubit systems.

d-wave superconductivity and Bogoliubov-Fermi surfaces in Rarita-Schwinger-Weyl semimetals

Julia M. Link, Igor Boettcher, and Igor F. Herbut

Phys. Rev. B 101, 184503 (2020) - Published 4 May, 2020

Quasiparticles appearing in Dirac or Weyl semimetals connect relativistic physics at high energies to ongoing studies of novel condensed matter states. Recently, the standard model of emergent particles in solids got a new entry with the observation in several candidate compounds, such as PdBiSe, of the spin-32 Rarita-Schwinger-Weyl fermion. In this work, the authors explore the uncharted territory of possible unconventional superconductivity in these materials. They find that for small carrier densities the d-wave order parameter forms the uniaxial nematic state known from liquid crystals, while at a higher chemical potential it yields the exotic ‘cyclic state’ which breaks time-reversal symmetry without showing any magnetization. Surprisingly, the latter phase also features sixteen small Bogoliubov-Fermi surfaces.

H3LiIr2O6 shows no magnetic order down to lowest temperatures, raising hopes for a true Kitaev spin liquid. Its structure reveals H bonds between honeycomb layers and theory has proposed hydrogen disorder to affect the magnetic exchange. Using dielectric spectroscopy, the authors report here dipolar relaxations in H3LiIr2O6 and D3LiIr2O6, mirroring the dynamics of protons or deuterons within the double-well potentials of the H bonds. Under cooling, thermal activation crosses over into quantum tunneling, establishing a quantum paraelectric state with quasistatic disorder. This supports the realization of the long-pursued Kitaev spin liquid.

Although superconducting qubits are one of the most promising systems for quantum information applications, a separate interface is required to allow for information distribution through optical links. Here, the authors investigate the suitability of 167Er3+:Y2SiO5 as a microwave-to-optical memory interface. This material holds considerable promise as it has an optical transition in the telecommunication band. The authors identify hyperfine transitions with long coherence times without an external magnetic field, which are suitable for interfacing with superconducting qubit systems.

d-wave superconductivity and Bogoliubov-Fermi surfaces in Rarita-Schwinger-Weyl semimetals

Phys. Rev. B 101, 184503 (2020) - Published 4 May, 2020

Quasiparticles appearing in Dirac or Weyl semimetals connect relativistic physics at high energies to ongoing studies of novel condensed matter states. Recently, the standard model of emergent particles in solids got a new entry with the observation in several candidate compounds, such as PdBiSe, of the spin-32 Rarita-Schwinger-Weyl fermion. In this work, the authors explore the uncharted territory of possible unconventional superconductivity in these materials. They find that for small carrier densities the d-wave order parameter forms the uniaxial nematic state known from liquid crystals, while at a higher chemical potential it yields the exotic ‘cyclic state’ which breaks time-reversal symmetry without showing any magnetization. Surprisingly, the latter phase also features sixteen small Bogoliubov-Fermi surfaces.
