Enhanced two-dimensional ferromagnetism in van der Waals β-UTe 3 monolayers

S. M. Thomas, Andres E. Llacsahuanga Allcca, Wolfgang Simeth, Caitlin S. Kengle et autres

The discovery of local-moment magnetism in van der Waals (vdW) semiconductors down to the single-layer limit has led to a paradigm shift in the understanding of two-dimensional (2D) magnets. The incorporation of strong electronic and magnetic correlations in 2D vdW metals remains …

Dichotomy of flat bands in the van der Waals ferromagnet Fe 5 GeTe 2

Han Wu, J. C. A. Huang, Chaowei Hu, Lei Chen et autres

Quantum materials with bands of narrow bandwidth near the Fermi level represent a promising platform for exploring a diverse range of fascinating physical phenomena, as the high density of states within the small energy window often enables the emergence of many-body physics. …

Effect of Electron Correlation on the Integer Quantum Hall Effect

Daniel Staros, Christopher Lane, Roxanne Tutchton, Jian‐Xin Zhu

We numerically investigate the effect of electron correlation on the integer quantum Hall effect in a square lattice. Increasing the correlation strength via the effective onsite repulsion parameter $U$ degrades the quantization of $ν= 1$ transverse conductance due to the interplay of …

Exact eigenvalues and experimental signatures of Heisenberg-Kitaev interactions in spin-1/2 quantum clusters

Evan M. Wilson, Jian‐Xin Zhu, J. T. Haraldsen

We investigate the thermodynamics and energy eigenstates of a spin-1/2 coupled trimer, tetramer in a star configuration, and tetrahedron. Using a Heisenberg Hamiltonian with additional Kitaev interactions, we explore the thermodynamic signatures of the Kitaev interaction. Our results show that introducing a …

Variational Quantum Simulations of a Two-Dimensional Frustrated Transverse-Field Ising Model on a Trapped-Ion Quantum Computer

Ammar Kirmani, Elijah Pelofske, Andreas Bärtschi, Stephan Eidenbenz et autres

Quantum computers are an ideal platform to study the ground state properties of strongly correlated systems due to the limitation of classical computing techniques particularly for systems exhibiting quantum phase transitions. While the error rates of Noisy Intermediate-Scale Quantum (NISQ) computers are …

Realizing supersymmetry in a digitized quantum device

Sutapa Samanta, Jian‐Xin Zhu, Armin Rahmani

The tricritical Ising model serves as an example of emergent spacetime supersymmetry, which can arise in condensed matter systems. In this work, we present a variational quantum algorithm to create this tricritical state on a digitized quantum computer. We successfully prepare the …

Electrodynamics of photo‐carriers in multiferroic Eu 0.75 Y 0.25 MnO 3

Yue Huang, Rolando Valdés Aguilar, S. A. Trugman, Sang‐Wook Cheong et autres

Abstract Understanding and controlling the antiferromagnetic order in multiferroic materials on an ultrafast time scale is a long standing area of interest, due to their potential applications in spintronics and ultrafast magnetoelectric switching. We present an optical pump‐terahertz (THz) probe study on …

Laser-driven Ultrafast Dynamics of a Fractional Quantum Hall System

Ammar Kirmani, Benedikt Fauseweh, Jian‐Xin Zhu

Fractional quantum Hall (FQH) systems are strongly interacting electron systems with topological order. These systems are characterized by novel ground states, fractionally charged and neutral excitations. The neutral excitations are dominated by a low-energy collective magnetoroton mode. Here we derive and use …

A data-driven approach for identification of novel organic ferroelectrics

Ayana Ghosh, Dennis Trujillo, Subhashis Hazarika, Elizabeth Schiesser et autres

Recent advances in the synthesis of polar molecular materials have produced practical alternatives to ferroelectric ceramics, opening up exciting new avenues for their incorporation into modern electronic devices. However, in order to realize the full potential of polar polymer and molecular crystals …
