S. Hayashida, V. Sundaramurthy, P. Puphal, M. Garcia-Fernandez, Ke-Jin Zhou, B. Fenk, M. Isobe, M. Minola, Y.-M. Wu, Y. E. Suyolcu, P. A. van Aken, B. Keimer, and M. Hepting

Phys. Rev. B 109, 235106 (2024) - Published 3 June, 2024

Infinite-layer nickelates are an emergent family of unconventional superconductors. Previous investigations have mostly focused on thin film samples, due to the complex crystal growth involving topochemical reductions. Here, the authors present the first spectroscopic investigation of bulk crystal infinite-layer nickelate LaNiO2 using resonant inelastic x-ray scattering. Their findings indicate that spin excitations are ubiquitous in infinite-layer nickelates, while the presence of charge order remains a subject of debate.

Dynamical correlation functions from complex time evolution

Xiaodong Cao, Yi Lu, E. Miles Stoudenmire, and Olivier Parcollet

Phys. Rev. B 109, 235110 (2024) - Published 5 June, 2024

As quantum systems evolve in time, their entanglement usually grows quickly, making tensor network methods inefficient. “Imaginary time” evolution is efficient, but extrapolating back to the real axis is ill-conditioned. Here, the authors show that complex time, a mixture of the two, remains efficient while allowing a controlled reconstruction technique. Therefore, one can reach significantly longer times, which they demonstrate by obtaining high-accuracy results for impurity models at low energies.

Spin-orbital ordering in alkali superoxides

Kohei Shibata, Makoto Naka, Harald O. Jeschke, and Junya Otsuki

Phys. Rev. B 109, 235115 (2024) - Published 7 June, 2024

Alkali superoxides have spin and orbital degrees of freedom due to an open p shell of the oxygen ion O2 with degenerate π orbitals. The complex magnetic, orbital, and structural phase transitions observed experimentally in this family of materials are only partly understood. Geometrical frustration is found, based on density functional theory, to be a key for understanding the rich variety in the behavior of these compounds. Solving the Kugel-Khomskii model for CsO2 in a mean field reveals an orbital ordering transition below which the material becomes a highly frustrated two-dimensional magnet.

Real-time quantum dynamics of thermal states with neural thermofields

Jannes Nys, Zakari Denis, and Giuseppe Carleo

Phys. Rev. B 109, 235120 (2024) - Published 10 June, 2024

Solving the time-dependent quantum many-body Schrquotodinger equation is a challenging task, especially for states at a finite temperature, where the environment affects the dynamics. Most existing approximating methods are designed to represent static thermal density matrices, 1D systems, and/or zero-temperature states. Here, the authors propose a method to study the real-time dynamics of thermal states in two dimensions, based on thermofield dynamics, variational Monte Carlo, and neural-network quantum states.

Effects of strain and defects on the topological properties of HfTe5

Na Hyun Jo, Omar A. Ashour, Zhixue Shu, Chris Jozwiak, Aaron Bostwick, Yang Wang, Eoghan Downey, Sae Hee Ryu, Kai Sun, Tai Kong, Sinéad M. Griffin, and Eli Rotenberg

Phys. Rev. B 109, 235122 (2024) - Published 10 June, 2024

Manipulating topological states holds significant interest in the field of condensed matter physics. Here, the authors control the topological phase and corresponding quasiparticle dynamics by managing defects, and further reverse these effects through in situ uniaxial stress control in HfTe5. The findings showcase the potential of employing both defect chemistry and strain engineering as tools to manipulate topological phase transitions and related many-body physics.

Spin fluctuations sufficient to mediate superconductivity in nickelates

Paul Worm, Qisi Wang, Motoharu Kitatani, Izabela Biało, Qiang Gao, Xiaolin Ren, Jaewon Choi, Diana Csontosová, Ke-Jin Zhou, Xingjiang Zhou, Zhihai Zhu, Liang Si, Johan Chang, Jan M. Tomczak, and Karsten Held

Phys. Rev. B 109, 235126 (2024) - Published 12 June, 2024

Many mechanisms for unconventional superconductivity have been proposed, but actually proving which one is in charge is challenging. Quite astonishingly, dynamical vertex approximation predict the superconducting phase diagram of novel nickelate superconductors, with the microscopic origin being antiferromagnetic spin fluctuations. The authors compare the antiferromagnetic spin fluctuations behind these calculations to experiment. The again good agreement gives an overall coherent and complete picture, and thus a high level of confidence that superconductivity in nickelates is indeed mediated by spin fluctuations.

Polaronic mechanism of Nagaoka ferromagnetism in Hubbard models

Rhine Samajdar and R. N. Bhatt

Phys. Rev. B 109, 235128 (2024) - Published 13 June, 2024

The Hubbard model, a key descriptor of strongly interacting electronic systems, typically features antiferromagnetic spin alignment. However, in certain idealized limits, the celebrated Nagaoka theorem predicts a ferromagnetic ground state. Here, the authors demonstrate how itinerant ferromagnetism arises in a host of real experimental systems without the infeasible constraints required by the Nagaoka theorem. In this universal mechanism, an individual dopant surrounds itself with a ferromagnetically aligned spin bubble, with the local polarons from multiple such dopants combining to create global ferromagnetic order.

Classification of electronic nematicity in three-dimensional crystals and quasicrystals

Matthias Hecker, Anant Rastogi, Daniel F. Agterberg, and Rafael M. Fernandes

Phys. Rev. B 109, 235148 (2024) - Published 25 June, 2024

Electronic nematicity, proposed as a novel correlated state of matter more than two decades ago, is being reported in an ever-growing number of materials. Yet, research on this topic has focused on realizations in quasi-two-dimensional lattices with fourfold or sixfold rotational symmetries. This work presents a systematic and unifying classification scheme for electronic nematicity in all crystallographic point groups and noncrystallographic groups relevant to quasicrystals and twisted materials. It reveals a rich nematic phenomenology described in terms of distinct types of Potts and clock models.

Band-gap discontinuity in semiconductor alloys with dissimilar wavefunction characters at the band edges

Xuefen Cai, Su-Huai Wei, Peter Deák, Jingxiu Yang, Chen Zhang, Bin Wang, Shu-Shen Li, and Hui-Xiong Deng

Phys. Rev. B 109, 235205 (2024) - Published 5 June, 2024

The authors clarify here the cause behind the discontinuous bandgap behavior in certain isovalent alloys by studying α-(Rh,Ga)2O3 alloys using first-principles calculations. This challenges the applicability of conventional empirical continuous rules. They demonstrate that this unusual behavior is due to the unconventional evolution of the wavefunction character at the band edges. This work emphasizes the importance of considering specific band-edge wavefunction character differences in endpoint materials for more accurate predictions of semiconductor alloy properties, which will help in designing better materials for electronics and optoelectronics.

Optical probing of the carrier-mediated coupling of the spin of two Co atoms in a quantum dot

L. Besombes, J. Kobak, and W. Pacuski

Phys. Rev. B 109, 235302 (2024) - Published 20 June, 2024

A direct band gap semiconductor quantum dot enables a spin-photon interface with embedded carriers or magnetic impurities, a key element in the establishment of quantum information networks. Spins of magnetic atoms carrying an orbital moment can also be interfaced with phonons and could be used to couple sound, spin, and light at the quantum level. The authors show here that injecting carriers into a quantum dot can induce correlation between two spins of distant magnetic atoms. Resonant optical access to the spin state of the two correlated atoms is conditioned by their position in the dot and by the local configuration of the strain.

Terahertz ratchet in graphene two-dimensional metamaterial formed by a patterned gate with an antidot array

I. Yahniuk, M. Hild, L. E. Golub, J. Amann, J. Eroms, D. Weiss, Wun-Hao Kang, Ming-Hao Liu, K. Watanabe, T. Taniguchi, and S. D. Ganichev

Phys. Rev. B 109, 235428 (2024) - Published 21 June, 2024

Photocurrents are generated by the ratchet effect – the combined action of a spatially periodic in-plane electrostatic potential and a periodically modulated radiation electric field caused by near-field diffraction. Polarized radiation is converted into a direct current due to the spatial asymmetry of the metamaterial. The ratchet current vector is gate tunable via a global back gate and a patterned gate, which control the lateral asymmetry of the system.

Photocurrents are generated by the ratchet effect – the combined action of a spatially periodic in-plane electrostatic potential and a periodically modulated radiation electric field caused by near-field diffraction. Polarized radiation is converted into a direct current due to the spatial asymmetry of the metamaterial. The ratchet current vector is gate tunable via a global back gate and a patterned gate, which control the lateral asymmetry of the system.
