Altermagnetic Anomalous Hall Effect and Spin--Edge-Locked Chiral Modes in a Modified Kane--Mele--Hubbard Model
Mohsen Hafez-Torbati, Alireza Qaiumzadeh
We establish a correlation-driven route to the altermagnetic anomalous Hall effect (AHE) and its associated \emph{spin--edge-locked} edge states in a modified Kane--Mele--Hubbard m…
High-Temperature Quantum Anomalous Hall Effect in Buckled Honeycomb Antiferromagnets
Mohsen Hafez-Torbati, Götz S. Uhrig
We propose Néel antiferromagnetic (AF) Mott insulators with a buckled honeycomb structure as potential candidates to host a high-temperature AF Chern insulator (AFCI). Using a gen…
From explicit to spontaneous charge order and the fate of antiferromagnetic quantum Hall state
Mohsen Hafez-Torbati
The antiferromagnetic quantum Hall insulator (AFQHI), where one of the spin components is in the quantum Hall state and the other in the trivial state, is an established phase emer…
Antiferromagnetic topological insulators in heavy-fermion systems
Mohsen Hafez-Torbati
The cooperation of electronic correlation and spin-orbit coupling can stabilize magnetic topological insulators which host novel quantum phenomena such as the quantum anomalous Hal…
Antiferromagnetic Chern insulator with large charge gap in heavy transition-metal compounds
Mohsen Hafez-Torbati, Götz S. Uhrig
Despite the discovery of multiple intrinsic magnetic topological insulators in recent years the observation of Chern insulators is still restricted to very low temperatures due to…
