Four-electron negative-U vacancy defects in antimony selenide

Xinwei Wang, Seán R. Kavanagh, David O. Scanlon, and Aron Walsh

Phys. Rev. B 108, 134102 (2023) - Published 4 October, 2023

Negative-U defects in solids break the assumption that like charges repel. The standard negative-U model describes the favorable attraction of a second electron to a defect centre. Here, the authors demonstrate an extension of negative-U behavior up to a change of four electrons. This occurs for the emerging photovoltaic compound Sb2Se3. The phenomenon is explained as a special case of valence alternation arising from the large change in structure and bonding that accompanies electron capture.

Internal clock of many-body delocalization

Ferdinand Evers, Ishita Modak, and Soumya Bera

Phys. Rev. B 108, 134204 (2023) - Published 26 October, 2023

For over two decades, researchers have investigated the effect of many-body interactions on Anderson localization. Early studies proposed many-body localization, i.e., strict particle confinement under strong disorder. Here, the authors challenge this notion by highlighting the prevalence of many-body delocalization in a fruit-fly model: the disordered Heisenberg chain. Its relaxation dynamics synchronize over various variables and parameters while adopting the entanglement entropy as an “internal clock”. These results suggest entanglement evolution as a novel temporal measure for a nuanced understanding of relaxation dynamics.

Scrambling and operator entanglement in local non-Hermitian quantum systems

Brian Barch, Namit Anand, Jeffrey Marshall, Eleanor Rieffel, and Paolo Zanardi

Phys. Rev. B 108, 134305 (2023) - Published 12 October, 2023

In weakly monitored quantum systems, traditional diagnostics of operator spreading such as out-of-time-ordered-correlators and Lieb-Robinson bounds can break down, as entanglement can spread at seemingly unbounded velocity. This has the adverse effect of making integrable and chaotic quantum dynamics appear identical. However, as the authors show here, the humble quantity of global operator entanglement remains a reliable metric of chaoticity in these systems. They elucidate this by studying entanglement phase transitions in a local, non-Hermitian transverse-field Ising model under the lens of operator and quenched entanglement dynamics.

Gapless spinons and a field-induced soliton gap in the hyperhoneycomb Cu oxalate framework compound [(C2H5)3NH]2Cu2(C2O4)3

C. Dissanayake, A. C. Jacko, K. Kumarasinghe, R. Munir, H. Siddiquee, W. J. Newsome, F. J. Uribe-Romo, E. S. Choi, S. Yadav, X.-Z. Hu, Y. Takano, S. Pakhira, D. C. Johnston, Q.-P. Ding, Y. Furukawa, B. J. Powell, and Y. Nakajima

Phys. Rev. B 108, 134418 (2023) - Published 13 October, 2023

Frustrated magnets can be platforms for quantum spin-liquid states. A putative spin-liquid candidate, the hyperhoneycomb Cu oxalate framework compound [(C2H5)3NH]2Cu2(C2O4)3 exhibits the absence of long-range order and presence of charge-neutral excitations in the Mott insulating state at low temperatures. Here, the authors demonstrate experimental evidence for gapless spinons and a field-induced soliton gap in this material with the aid of theoretical calculations, and attribute them to weakly coupled antiferromagnetic Heisenberg chains, rather than a previously proposed spin-liquid state.

Microscopic details of two-dimensional spectroscopy of one-dimensional quantum Ising magnets

GiBaik Sim, Frank Pollmann, and Johannes Knolle

Phys. Rev. B 108, 134423 (2023) - Published 17 October, 2023

This work explores the effectiveness of two-dimensional coherent spectroscopy for understanding the microscopic properties of quantum magnets. Motivated by experiments on the Ising chain magnet CoNb2O6, it is shown that the 2D spectra are markedly different for the two proposed microscopic Hamiltonians - the transverse field Ising model and the twisted Kitaev spin chain - even though the linear response is similar. The findings showcase the power of 2D spectroscopy for quantifying microscopic descriptions and understanding the dynamics of fractionalized excitations of quantum magnets.

Quantum spin liquids on the diamond lattice

Aishwarya Chauhan, Atanu Maity, Chunxiao Liu, Jonas Sonnenschein, Francesco Ferrari, and Yasir Iqbal

Phys. Rev. B 108, 134424 (2023) - Published 18 October, 2023

The diamond lattice has been a promising playground for both classical and quantum spin liquids. Here, the authors conduct a comprehensive symmetry classification of S=½ quantum spin liquids with SU(2), U(1), and ℤ2 gauge fields, and present dynamical spin structure factors within a self-consistent simulation. The authors highlight three discoveries: spinon Ansätze with robust gapless nodal loops, topological bands realizing topological insulators, and that Gutzwiller projection of the 0- and π-flux SU(2) spin liquids generates long-range Néel order.

Resonant x-ray diffraction study using circularly polarized x rays on antiferromagnetic TbB4

R. Misawa, K. Arakawa, T. Yoshioka, H. Ueda, F. Iga, K. Tamasaku, Y. Tanaka, and T. Kimura

Phys. Rev. B 108, 134433 (2023) - Published 24 October, 2023

The interference effect between the magnetic scattering and the charge scattering in resonant x-ray diffraction (RXD) leads to circular dichroism. The authors utilize this effect here to distinguish the antiferromagnetic (AFM) domain state in the noncollinear antiferromagnet TbB4, breaking both the space-inversion (P) and time-reversal (T) symmetries but preserving the combined PT symmetry. This result shows that circularly polarized RXD using the interference effect enables us to detect AFM order parameters and spatially resolve the domain state in PT-symmetric AFM materials.

Negative tripartite mutual information after quantum quenches in integrable systems

Fabio Caceffo and Vincenzo Alba

Phys. Rev. B 108, 134434 (2023) - Published 25 October, 2023

The tripartite information (TMI) has emerged as a tool to sieve quantum correlations in quantum many-body systems. A negative TMI is interpreted as evidence for quantum information delocalization in chaotic systems. Here, the authors show that a negative TMI can appear in out-of-equilibrium free-fermion models, and it is linked to the presence of entangled multiplets of excitations. Negative TMI signals a weakening of the relationship between entanglement and thermodynamics, which can be understood in a generalized quasiparticle picture framework.

Unveiling the impact of temperature on magnon diffuse scattering detection in the transmission electron microscope

José Ángel Castellanos-Reyes, Paul Zeiger, Anders Bergman, Demie Kepaptsoglou, Quentin M. Ramasse, Juan Carlos Idrobo, and Ján Rusz

Phys. Rev. B 108, 134435 (2023) - Published 27 October, 2023

This study delves deeply into the complexities of magnon diffuse scattering (MDS) in bcc Fe, unraveling the interplay between atomic vibrations and magnon signals in scanning transmission electron microscopy (STEM). The work details the role of temperature to explore feasible paths for MDS detection that could bring new understanding of magnetic solid-state phenomena at the nanometer scale.

Dynamical vortex transitions in a gate-tunable two-dimensional Josephson junction array

C. G. L. Bøttcher, F. Nichele, J. Shabani, C. J. Palmstrøm, and C. M. Marcus

Phys. Rev. B 108, 134517 (2023) - Published 27 October, 2023

The sudden depinning of vortices with increasing current through a super-semihybrid Josephson junction array results in a burst of differential resistance at integer and half-integer peaks of critical current. A striking feature is the split feature at f=0, indicating the absence of vortices at precisely zero field. The flat-topped portion at f=1/2 and the slanted top part at f=1 also reveal features of how the dynamical transition occurs.

The interference effect between the magnetic scattering and the charge scattering in resonant x-ray diffraction (RXD) leads to circular dichroism. The authors utilize this effect here to distinguish the antiferromagnetic (AFM) domain state in the noncollinear antiferromagnet TbB4, breaking both the space-inversion (P) and time-reversal (T) symmetries but preserving the combined PT symmetry. This result shows that circularly polarized RXD using the interference effect enables us to detect AFM order parameters and spatially resolve the domain state in PT-symmetric AFM materials.

Negative tripartite mutual information after quantum quenches in integrable systems

Phys. Rev. B 108, 134434 (2023) - Published 25 October, 2023

The tripartite information (TMI) has emerged as a tool to sieve quantum correlations in quantum many-body systems. A negative TMI is interpreted as evidence for quantum information delocalization in chaotic systems. Here, the authors show that a negative TMI can appear in out-of-equilibrium free-fermion models, and it is linked to the presence of entangled multiplets of excitations. Negative TMI signals a weakening of the relationship between entanglement and thermodynamics, which can be understood in a generalized quasiparticle picture framework.

This study delves deeply into the complexities of magnon diffuse scattering (MDS) in bcc Fe, unraveling the interplay between atomic vibrations and magnon signals in scanning transmission electron microscopy (STEM). The work details the role of temperature to explore feasible paths for MDS detection that could bring new understanding of magnetic solid-state phenomena at the nanometer scale.

The sudden depinning of vortices with increasing current through a super-semihybrid Josephson junction array results in a burst of differential resistance at integer and half-integer peaks of critical current. A striking feature is the split feature at f=0, indicating the absence of vortices at precisely zero field. The flat-topped portion at f=1/2 and the slanted top part at f=1 also reveal features of how the dynamical transition occurs.
