Spin-charge separation in two-leg t-J ladders
Luhang Yang, Elbio Dagotto
Spin-charge separation is a hallmark of one-dimensional fermionic systems, yet its realization in higher dimensions remains an open question. To address this issue, we investigate…
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…
Spinon excitations and spin correlations in the one-dimensional quantum magnet -VOSO probed by Raman spectroscopy
Dirk Wulferding, Diana Lucia Quintero-Castro, Pontus Laurell +3
Fractionalized excitations such as spinons and anyons have emerged as a central theme in condensed matter physics with broad implications for superconductivity, quantum statistics,…
Effects of the Next-Nearest-Neighbor Hopping on the Low-Dimensional Hubbard Model: Ferromagnetism, Antiferromagnetism, and Superconductivity
Luhang Yang, Adrian E. Feiguin, Thomas P. Devereaux +1
The Hubbard model has attracted considerable interest due to its prototypical role in describing strongly interacting electronic systems, such as high-critical-temperature supercon…
Spin-Orbital Altermagnetism
Zi-Ming Wang, Yang Zhang, Song-Bo Zhang +4
Altermagnet is a newly discovered magnetic phase, characterized by non-relativistic spin-splitting that has been experimentally observed. Here, we introduce a framework dubbed {\it…
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…
