Elastoresistive and elastocaloric anomalies at magnetic and electronic-nematic critical points

Alexander T. Hristov, Matthias S. Ikeda, Johanna C. Palmstrom, Philip Walmsley, and Ian R. Fisher

Phys. Rev. B 99, 100101(R) (2019) - Published 11 March, 2019

This work identifies critical anomalies in measurements of the elastoresistivity and the elastocaloric coefficient at both the structural-nematic and antiferromagnetic phase transitions of an iron pnictide. The authors explain the magnitude and functional forms of these critical anomalies from the strain dependence of the transition temperatures. Because there is typically a strain of the trivial representation that couples to the square of any order parameter, these effects should manifest at all second order transitions. The increasing adoption of strain techniques makes this work particularly timely.

Acoustic flat lensing using an indefinite medium

M. Dubois, J. Perchoux, A. L. Vanel, C. Tronche, Y. Achaoui, G. Dupont, K. Bertling, A. D. Rakić, T. Antonakakis, S. Enoch, R. Abdeddaim, R. V. Craster, and S. Guenneau

Phys. Rev. B 99, 100301(R) (2019) - Published 13 March, 2019

Acoustic flat lensing is experimentally confirmed, using optical feedback interferometry, for a phononic array of rigid spheres placed in air. The array behaves as an indefinite medium characterized by tensors whose principal elements have different signs, allowing for effects such as negative refraction and high impedance surface reflection. Here, this behavior is achieved in a narrow frequency region around 10.6 kHz, where the acoustic band displays a hidden singularity unveiled by an unusual path in the irreducible Brillouin zone.

Partial ordering and phase elasticity in the MnGe short-period helimagnet

N. Martin, I. Mirebeau, C. Franz, G. Chaboussant, L. N. Fomicheva, and A. V. Tsvyashchenko

Phys. Rev. B 99, 100402(R) (2019) - Published 13 March, 2019

The authors report on a transition from a commensurate (C) to an incommensurate (IC) helimagnetic state as seen in both the static and dynamic properties of the MnGe alloy. Using high-resolution neutron spectroscopy, they observe gapless spin fluctuations with a typical lifetime τh=/Γh 20 ps in the IC phase. They continuously vanish upon approaching the C phase, where the helical wavelength λh=2π/Qh saturates to a value close to six lattice constants. Noting that the onset of this peculiar dynamics coincides with the sign reversal of the anomalous Hall effect, this work underscores the crucial role of spin fluctuations in the physics of “skyrmiogenic” compounds.

Stokes–anti-Stokes correlated photon properties akin to photonic Cooper pairs

Filomeno S. de Aguiar Júnior, André Saraiva, Marcelo F. Santos, Belita Koiller, Reinaldo de Melo e Souza, Arthur Patrocínio Pena, Raigna A. Silva, Carlos H. Monken, and Ado Jorio

Phys. Rev. B 99, 100503(R) (2019) - Published 13 March, 2019

Photons interact in condensed matter through the same mechanism that forms Cooper pairs in superconductors. The production rate depends on the energy shifts, which in the BCS theory determines whether interaction is attractive or repulsive. Only correlated photons in the case of attractive interactions are observed. While traditional photon-phonon collisions scatter light in all directions, the correlated photons follow the same path as the noninteracting laser. The observed phenomenon is rare, but the authors indicate paths to achieve higher interaction energies.

Correlation-induced localization

P. A. Nosov, I. M. Khaymovich, and V. E. Kravtsov

Phys. Rev. B 99, 104203 (2019) - Published 19 March, 2019

Conventional Anderson localization is due to destructive interference of matter waves described by local random Hamiltonians. Correlations in random diagonal elements of such a Hamiltonian are known to favor delocalization. Systems described by nonlocal Hamiltonians have become experimentally accessible recently. The authors consider two families of such random-matrix Hamiltonians with correlations in the long-range hopping terms and demonstrate that, as correlations become stronger, localization is enhanced while the wave-function ergodicity progressively deteriorates.

Percolation in Fock space as a proxy for many-body localization

Sthitadhi Roy, J. T. Chalker, and David E. Logan

Phys. Rev. B 99, 104206 (2019) - Published 25 March, 2019

Drawing motivation from the fact that eigenstates in many-body localized and ergodic phases behave differently with regard to their support on the Fock space, the authors study a classical percolation problem in Fock space that captures certain aspects of the many-body localization transition. In particular, it has two classical phases that provide simplified pictures of the extended and many-body localized states. At weak disorder, the entire Fock space is contained in a single cluster, whereas for strong disorder, the typical cluster size scales with the Fock-space dimension in a subvolume law fashion.

General method for atomistic spin-lattice dynamics with first-principles accuracy

Johan Hellsvik, Danny Thonig, Klas Modin, Diana Iuşan, Anders Bergman, Olle Eriksson, Lars Bergqvist, and Anna Delin

Phys. Rev. B 99, 104302 (2019) - Published 15 March, 2019

Conservation of angular momentum implies that when a material changes its magnetic state, the resulting change in angular momentum must appear in some other form. In materials, the atomic magnetic moment and lattice degrees of freedom are coupled through the electronic subsystem. Here, the authors present a computationally efficient and general first-principles based method for spin-lattice simulations, opening the door for quantitative description and understanding of the microscopic origin of ultrafast demagnetization, magnetocalorics, and spincaloritronics.

Theory for time-resolved resonant inelastic x-ray scattering

Yuan Chen, Yao Wang, Chunjing Jia, Brian Moritz, Andrij M. Shvaika, James K. Freericks, and Thomas P. Devereaux

Phys. Rev. B 99, 104306 (2019) - Published 22 March, 2019

How do we map collective excitations with time, momentum, and energy resolution? Development of time-resolved resonant inelastic x-ray scattering (tr-RIXS) shows promise. Here, the authors present a theory for the tr-RIXS cross section, and as a proof of principle, they apply the theory to single-band models to elucidate the dynamics of particle-hole excitations. This work provides a crucial bridge for understanding how excitations from complicated phases manifest in time-resolved resonant scattering experiments.

Orientation-dependent direct and inverse spin Hall effects in Co60Fe20B20

Joel Cramer, Andrew Ross, Samridh Jaiswal, Lorenzo Baldrati, Romain Lebrun, and Mathias Kläui

Phys. Rev. B 99, 104414 (2019) - Published 11 March, 2019

The spin Hall effect is a key element of various spintronics applications. Here, the authors study the orientation-dependent interconversion of spin and charge information in Co60Fe20B20. In a nonlocal magnon transport using Y3Fe5O12 as a spin conduit, the spin Hall effect amplitude depends on the relative alignment between the Y3Fe5O12 and Co60Fe20B20 magnetization vectors.

Diagnosing phases of magnetic insulators via noise magnetometry with spin qubits

Shubhayu Chatterjee, Joaquin F. Rodriguez-Nieva, and Eugene Demler

Phys. Rev. B 99, 104425 (2019) - Published 21 March, 2019

Two-dimensional magnetic insulators exhibit a plethora of competing ground states, such as ordered (anti)ferromagnets, exotic quantum spin liquid states, and random singlet phases. Spin liquids, in particular, are collective phases of matter which have eluded discovery for several decades. Although there are many promising candidate materials for their realization, the central challenges for the clear diagnosis of a spin liquid has been the lack of experimental probes to access their emergent excitations. Here, the authors propose that spin qubit magnetometers grant access to these excitations and, therefore, can be used as a diagnostic of ground states in magnetic insulators.

Electromagnetic proximity effect controlled by spin-triplet correlations in superconducting spin-valve structures

Zh. Devizorova, S. V. Mironov, A. S. Mel'nikov, and A. Buzdin

Phys. Rev. B 99, 104519 (2019) - Published 28 March, 2019

The spin-triplet correlations in superconducting spin-valve structures arising in the presence of noncollinear textures of magnetic moment are shown to enhance strongly the electromagnetic proximity effect, i.e., the long-range leakage of the magnetic field from the ferromagnet (F) to the superconducting (S) layer. The results here provide a natural explanation of the puzzling enhancement of spontaneous magnetic fields induced by noncollinear magnetic structures observed in a wide class of layered S/F systems.

Two-dimensional magnetic insulators exhibit a plethora of competing ground states, such as ordered (anti)ferromagnets, exotic quantum spin liquid states, and random singlet phases. Spin liquids, in particular, are collective phases of matter which have eluded discovery for several decades. Although there are many promising candidate materials for their realization, the central challenges for the clear diagnosis of a spin liquid has been the lack of experimental probes to access their emergent excitations. Here, the authors propose that spin qubit magnetometers grant access to these excitations and, therefore, can be used as a diagnostic of ground states in magnetic insulators.

The spin-triplet correlations in superconducting spin-valve structures arising in the presence of noncollinear textures of magnetic moment are shown to enhance strongly the electromagnetic proximity effect, i.e., the long-range leakage of the magnetic field from the ferromagnet (F) to the superconducting (S) layer. The results here provide a natural explanation of the puzzling enhancement of spontaneous magnetic fields induced by noncollinear magnetic structures observed in a wide class of layered S/F systems.
