Quantum Wake Dynamics from Distinct Spectroscopic Perturbations
Umesh Kumar, Gonzalo Alvarez, David Alan Tennant +1
Quantum wake dynamics in quantum magnets have recently been inferred from the dynamical spin structure factor, which probes only a restricted class of local perturbations. Here, we…
Electrically Programmable Correlated Topology and Magnetism in a Moiré Trilayer
Christiano Wang Beach, Courtney Baier, Kaijie Yang +15
Strong electron-electron interactions underlie a wide range of quantum many-body phenomena, including magnetism, superconductivity, and charge fractionalization. A central goal is…
Berry curvature and field-induced intrinsic anomalous Hall effect in an antiferromagnet FeTe
Satoshi Okamoto, Adriana Moreo, Naoto Nagaosa +1
Berry curvature is ubiquitous in condensed matter physics and materials science. Its main consequence is the intrinsic anomalous Hall effect (AHE) in magnetic materials and plays a…
Kinetic obstruction to pairing in the doped Kitaev-Heisenberg ladder
Bradraj Pandey, Bo Xiao, Satoshi Okamoto +4
We investigate the hole-doped Kitaev-Heisenberg (--) model on a two-leg ladder geometry using the density-matrix renormalization group (DMRG). We first consider the behavi…
Simulation of Topological -Gates via Braiding of Majorana Zero Modes in an Interacting Quantum Dot System
Bradraj Pandey, Satoshi Okamoto, Pontus Laurell +2
Recent advances in quantum dot platforms have opened new pathways for realizing Majorana zero modes (MZMs) and simulating topological quantum computation. Here we propose an experi…
General trends of electronic structures, superconducting pairing, and magnetic correlations in the Ruddlesden-Popper nickelate -layered superconductors LaNiO
Yang Zhang, Ling-Fang Lin, Adriana Moreo +3
We report a comprehensive theoretical analysis of the Ruddlesden-Popper layered nickelates LaNiO ( to 6) under pressure. Our results suggest that, while…
