Ferroelectric Altermagnetic Chern Insulator in magnetic field: electrical control of the Chern number
Meysam Bagheri Tagani, Carmine Autieri
We investigate electrically controllable Chern topology in a two-dimensional compensated (d)-wave altermagnet described by a lattice-regularized Bernevig--Hughes--Zhang model. In t…

Quantum anomalous Hall conductivity in altermagnets under applied magnetic field
Meysam Bagheri Tagani, Amar Fakhredine, Carmine Autieri
We investigate the emergence of quantum anomalous Hall conductivity in a two-dimensional -wave altermagnet on a Lieb lattice under an external magnetic field. Altermagnetic orde…
