Universality of grain boundary phases in fcc metals: Case study on high-angle [111] symmetric tilt grain boundaries

Tobias Brink, Lena Langenohl, Hanna Bishara, and Gerhard Dehm

Phys. Rev. B 107, 054103 (2023) - Published 10 February, 2023

It has been reported that different ordered structures can appear at the same grain boundaries. Thermodynamically, they can be regarded as interface phases (“complexions”). The authors use atomistic simulations to show that several fcc transition and post-transition metals exhibit the same two grain boundary phases in [111] tilt grain boundaries. This remains true even when using unphysical pair potentials, highlighting that the occurrence of different grain boundary phases is not an exceptional special case, but common across different materials.

Ferroelectric switching pathways and domain structure of SrBi2(Ta,Nb)2O9 from first principles

Nabaraj Pokhrel and Elizabeth A. Nowadnick

Phys. Rev. B 107, 054108 (2023) - Published 23 February, 2023

The energy barrier for polarization reversal is a key property that impacts the performance of ferroelectric materials. Here, the authors combine symmetry analysis and first-principles calculations to understand the origin of low-energy polarization switching in the Aurivillius-phase ferroelectrics SrBi2Ta2O9 and SrBi2Nb2O9. They show that polarization reverses via a low-energy two-step process facilitated by nonpolar structural order parameter rotations. Analysis of the ferroelectric domain structure shows that the formation of domain wall vortices is energetically favorable.

Influence of chirp and carrier-envelope phase on noninteger high-harmonic generation

Maximilian Graml, Maximilian Nitsch, Adrian Seith, Ferdinand Evers, and Jan Wilhelm

Phys. Rev. B 107, 054305 (2023) - Published 8 February, 2023

For high-harmonic generation, an intense laser pulse is targeted on a substrate producing high-frequency electromagnetic radiation. The high-harmonic spectrum emitted is strongly influenced by the properties of the substrate material and the laser pulse waveform. Here, the authors derive a simple analytical formula that describes the relation between laser pulse parameters and peak positions in the high-harmonic spectrum. The formula explains quantitatively why the high-harmonic spectrum may peak at frequencies that are not integer multiples of the laser pumping frequency.

Surface dynamics of graphite probed by soft x-ray linear dichroism in Auger-emission yield

G. Schiwietz, T. Kachel, R. Mitzner, and K. Holldack

Phys. Rev. B 107, 054306 (2023) - Published 13 February, 2023

Element-specific investigation of the dynamics of surface atoms is not a trivial task. Here, the authors show that time-resolved near-edge x-ray absorption for strongly anisotropic excitation resonances – combined with Auger-electron detection – yields such information, whereby the small Auger-electron escape depth provides surface sensitivity. The method is applied to highly oriented graphite in a pump-probe scheme, based on femtosecond laser excitation and x-ray probe pulses with variable polarization direction and delay time, both of which influence transient changes in the KVV Auger yield.

Multipartite entanglement in the one-dimensional spin-12 Heisenberg antiferromagnet

Varun Menon, Nicholas E. Sherman, Maxime Dupont, Allen O. Scheie, D. Alan Tennant, and Joel E. Moore

Phys. Rev. B 107, 054422 (2023) - Published 17 February, 2023

Multipartite entanglement was thought to be intrinsically difficult to measure in solids, but recent work has established connections between multipartite entanglement, dynamic susceptibilities, and neutron scattering data, via the quantum Fisher information. This work focuses on the paradigmatic spin-half chain and shows that there are further simplifications: even static structure factors contain quantitative information about multipartite entanglement at low temperatures. Theory, numerics, and experiment then suggest that a high degree of multipartite entanglement is observable in Heisenberg chain compounds, including KCuF3.

Scanning tunneling spectroscopy of Majorana zero modes in a Kitaev spin liquid

Tim Bauer, Lucas R. D. Freitas, Rodrigo G. Pereira, and Reinhold Egger

Phys. Rev. B 107, 054432 (2023) - Published 22 February, 2023

The experimental detection of Majorana zero modes represents a major open problem. In topological superconductors, scanning tunneling spectroscopy provides evidence through zero-bias conductance peaks, which can however be confused with disorder-induced Andreev states. The theory here suggests that the Majorana zero modes bound to vortices in Kitaev spin liquids offer a more favorable testing ground: the Majorana-induced conductance features found are quite distinct from those of an alternative scenario based on magnons.

Heat conduction in herbertsmithite: Field dependence at the onset of the quantum spin liquid regime

Quentin Barthélemy, Étienne Lefrançois, Jordan Baglo, Patrick Bourgeois-Hope, Dipranjan Chatterjee, Pierre Lefloïc, Matias Velázquez, Victor Balédent, Bernard Bernu, Nicolas Doiron-Leyraud, Fabrice Bert, Philippe Mendels, and Louis Taillefer

Phys. Rev. B 107, 054434 (2023) - Published 23 February, 2023

Thermal conductivity and thermal Hall effect measurements in the quantum kagome antiferromagnet herbertsmithite reveal that there is no significant contribution to the heat conduction from mobile spin excitations. A clear field dependence of the thermal conductivity is discovered to onset at a new temperature scale, attributed to the establishment of a quantum spin liquid and the gradual polarization of magnetic defects. Their magnetization profile is extracted and found incompatible with a Brillouin function, indicating that they are not isolated paramagnetic objects.

Spin wave spectra of single crystal CoPS3

A. R. Wildes, B. Fåk, U. B. Hansen, M. Enderle, J. R. Stewart, L. Testa, H. M. Rønnow, C. Kim, and Je-Geun Park

Phys. Rev. B 107, 054438 (2023) - Published 27 February, 2023

CoPS3 is a van der Waals antiferromagnet with the Co2+ ions forming decoupled honeycomb layers. It was a candidate to host exotic magnetic properties such as valence-bond states or Kitaev-like physics. Here, the authors show, using neutron inelastic scattering, that CoPS3 does not have these states. Instead, well-defined excitations are observed that are accurately modeled using linear spin wave theory with high-spin S=3/2 and biaxial single-ion anisotropy, giving insight for the reasons behind the absence of exotic states.

Spin-dependent coupling of supercurrent and nonequilibrium quasiparticles in high-field superconductors

P. Maier and D. Beckmann

Phys. Rev. B 107, 054504 (2023) - Published 8 February, 2023

The interplay of the spin degree of freedom with supercurrents is investigated here in the context of superconducting spintronics. Based on a recent theoretical prediction, the authors experimentally demonstrate a spin-dependent coupling of supercurrent and nonequilibrium quasiparticles. The coupling appears when the superconductor is subject to a large spin splitting, in this case a Zeeman splitting induced by an applied magnetic field. The results may be useful for the mutual control of spin-polarized supercurrents and quasiparticles in superconducting spintronics devices.

The interplay of the spin degree of freedom with supercurrents is investigated here in the context of superconducting spintronics. Based on a recent theoretical prediction, the authors experimentally demonstrate a spin-dependent coupling of supercurrent and nonequilibrium quasiparticles. The coupling appears when the superconductor is subject to a large spin splitting, in this case a Zeeman splitting induced by an applied magnetic field. The results may be useful for the mutual control of spin-polarized supercurrents and quasiparticles in superconducting spintronics devices.
