Competing structural instabilities in Bi2SiO5

A. Girard, H. Taniguchi, S. M. Souliou, M. Stekiel, W. Morgenroth, A. Minelli, A. Kuwabara, A. Bosak, and B. Winkler

Phys. Rev. B 98, 134102 (2018) - Published 9 October, 2018

Bi2SiO5 recently emerged as a promising ambient-temperature lead-free ferroelectric with a Curie temperature of 663 K, where the ferroelectricity arises from the tilt of quasi-one-dimensional SiO4 chains. Here, the authors analyze the competition between ferroelectric and antiferroelectric instabilities by investigating the characteristic temperature-dependent phonon energies at the center and the edge of the Brillouin zone, respectively. The direct evidence for this competition opens the way towards tuning the properties of Bi2SiO5 by application of pressure or electrical field.

Localization with random time-periodic quantum circuits

Christoph Sünderhauf, David Pérez-García, David A. Huse, Norbert Schuch, and J. Ignacio Cirac

Phys. Rev. B 98, 134204 (2018) - Published 30 October, 2018

Driven quantum systems can exhibit very different physics, such as thermalization or localization, depending on the type and amount of disorder. Here, the authors study time-periodic unitary circuits (a discrete version of driven quantum systems) for both spin and fermionic systems. Using new analytical and numerical tools, they are able to identify conditions under which such systems exhibit localizing or thermalizing behavior, and characterize how the system transitions to an MBL phase as the disorder in the interactions is increased.

Thermal stability of metastable magnetic skyrmions: Entropic narrowing and significance of internal eigenmodes

L. Desplat, D. Suess, J-V. Kim, and R. L. Stamps

Phys. Rev. B 98, 134407 (2018) - Published 4 October, 2018

Magnetic skyrmions are particlelike, topologically nontrivial spin textures. Isolated skyrmions represent metastable excitations of the ferromagnetic ground state and can be long-lived. For potential applications such as memory and logic devices, it is essential to quantitatively understand their stability against thermal fluctuations. Here, the authors apply transition state theory to directly compute the lifetimes of isolated skyrmions for two annihilation mechanisms: escape through a boundary and collapse. The internal modes of the skyrmion are found to play a dominant role in the thermally activated transitions compared to spin wave excitations. Moreover, a strong entropic contribution to the Arrhenius prefactor, linked to the internal modes, is highlighted.

Influence of the magnetic field on the stability of the multiferroic conical spin arrangement of Mn0.80Co0.20WO4

I. Urcelay-Olabarria, E. Ressouche, V. Y. Ivanov, V. Skumryev, Z. Wang, Y. Skourski, A. M. Balbashov, Yu. F. Popov, G. P. Vorob'ev, N. Qureshi, J. L. García-Muñoz, and A. A. Mukhin

Phys. Rev. B 98, 134430 (2018) - Published 17 October, 2018

The synergetic use of macroscopic magnetization, electric polarization, and single-crystal neutron diffraction techniques allows the tracking of the evolution of the magnetic structures (in magnetic fields up to 60 T) of the multiferroic Mn0.80Co0.20WO4, which has an antiferromagnetic conical ground state. The complete magnetoelectric phase diagrams for the three distinct magnetic directions (the easy and the hard magnetic directions and the b crystallographic axis) are constructed. Marked differences are found in the topologies between the phase diagrams, which might be common for other magnetic materials possessing conical antiferromagnetic structures.

Magnetic structure and spin correlations in magnetoelectric honeycomb Mn4Ta2O9

N. Narayanan, A. Senyshyn, D. Mikhailova, T. Faske, T. Lu, Z. Liu, B. Weise, H. Ehrenberg, R. A. Mole, W. D. Hutchison, H. Fuess, G. J. McIntyre, Y. Liu, and D. Yu

Phys. Rev. B 98, 134438 (2018) - Published 22 October, 2018

The coupling between magnetic ordering and electric polarization in magnetoelectrics is technically relevant and not yet completely understood. The elucidation of this requires a comprehension of underlying magnetic interactions and the electronic structure. Here, the authors investigate the magnetoelectric honeycomb compound Mn4Ta2O9, by means of neutron scattering and electronic structure calculations, to reveal the ingredients that determine the ground state. For this compound, the ground state is determined by an electron correlation assisted magnetic dipole-dipole interaction. The investigation here offers detailed insight into the factors that determine the ground-state manifold and the role of electron correlation on the strength of anisotropy.

Sign-reversal superconducting gaps revealed by phase-referenced quasiparticle interference of impurity-induced bound states in (Li1xFex)OHFe1yZnySe

Phys. Rev. B 98, 134503 (2018) - Published 11 October, 2018

It is very important, but not easy, to determine the superconducting gap function in unconventional superconductors. The key issue concerns whether there is a sign change in the gap function. In iron-based superconductors, this becomes even more difficult due to the complexity of multiple Fe 3d orbitals. Here, the authors adopt a recently proposed method – phase-referenced quasiparticle interference (QPI) of defect-bound states (DBS) via scanning tunneling microscope/spectroscopy – and visualize directly the gap sign change of the superconducting gaps in the iron-based superconductor (Li1xFex)OHFe1yZnySe. This work provides an easy and feasible way for detecting the gap function of unconventional superconductors.

Unconventional superconductivity in the single-atom-layer alloy Si(111)3×3(Tl,Pb)

T. Nakamura, H. Kim, S. Ichinokura, A. Takayama, A. V. Zotov, A. A. Saranin, Y. Hasegawa, and S. Hasegawa

Phys. Rev. B 98, 134505 (2018) - Published 16 October, 2018

The Si(111)-3×3-(Tl, Pb) surface has recently emerged as being a two-dimensional one-atom thick superconductor with spin-split bands, due to the Rashba-Bychkov effect. Here, the authors use scanning tunneling microscopy and spectroscopy to measure its superconductivity. They observe the unconventional nature, the anisotropy of the superconducting gap, and the pseudogap structure under a magnetic field. These results promote further experimental and theoretical investigations of possible parity-broken superconductors.

Phase separation at the dimer-superconductor transition in Ir1xRhxTe2

R. Yu, S. Banerjee, H. Lei, M. Abeykoon, C. Petrovic, Z. Guguchia, and E. S. Bozin

Phys. Rev. B 98, 134506 (2018) - Published 16 October, 2018

Unconventional superconductivity often appears in proximity of symmetry-breaking electronic and magnetic orders. The relevance of spatiotemporal fluctuations of these orders for the superconducting pairing remains an open question. Here, nanoscale broken-symmetry states are probed by high-energy x-rays in a layered iridium ditelluride superconductor, where superconductivity emerges from an ordered dimer state. The study finds no fingerprints of dimer fluctuations in the superconducting compositional regime, yet provides evidence for the coexistence of superconductivity and nanoscale dimerization close to the phase boundary of these two electronic states.

For this compound, the ground state is determined by an electron correlation assisted magnetic dipole-dipole interaction. The investigation here offers detailed insight into the factors that determine the ground-state manifold and the role of electron correlation on the strength of anisotropy.

It is very important, but not easy, to determine the superconducting gap function in unconventional superconductors. The key issue concerns whether there is a sign change in the gap function. In iron-based superconductors, this becomes even more difficult due to the complexity of multiple Fe 3d orbitals. Here, the authors adopt a recently proposed method – phase-referenced quasiparticle interference (QPI) of defect-bound states (DBS) via scanning tunneling microscope/spectroscopy – and visualize directly the gap sign change of the superconducting gaps in the iron-based superconductor (Li1xFex)OHFe1yZnySe. This work provides an easy and feasible way for detecting the gap function of unconventional superconductors.

The Si(111)-3×3-(Tl, Pb) surface has recently emerged as being a two-dimensional one-atom thick superconductor with spin-split bands, due to the Rashba-Bychkov effect. Here, the authors use scanning tunneling microscopy and spectroscopy to measure its superconductivity. They observe the unconventional nature, the anisotropy of the superconducting gap, and the pseudogap structure under a magnetic field. These results promote further experimental and theoretical investigations of possible parity-broken superconductors.

Phase separation at the dimer-superconductor transition in Ir1xRhxTe2

Unconventional superconductivity often appears in proximity of symmetry-breaking electronic and magnetic orders. The relevance of spatiotemporal fluctuations of these orders for the superconducting pairing remains an open question. Here, nanoscale broken-symmetry states are probed by high-energy x-rays in a layered iridium ditelluride superconductor, where superconductivity emerges from an ordered dimer state. The study finds no fingerprints of dimer fluctuations in the superconducting compositional regime, yet provides evidence for the coexistence of superconductivity and nanoscale dimerization close to the phase boundary of these two electronic states.
