Magnetotransport and Phase competition in three-dimensional Hubbard-Holstein model at half-filling
Sandip Halder, Moshe Schechter
We investigate the magnetotransport properties of the one-band Hubbard-Holstein model at half-filling in three dimensions (3D) using exact diagonalization based semi-classical Mont…

Exploring the magnetic states in the one-band Hubbard model: Impact of long-range hoppings
Sudip Mandal, Sandip Halder, Kalpataru Pradhan
Correlated electron systems with competing interactions provide a valuable platform for examining exotic magnetic phases. Theoretical models often focus on nearest-neighbor interac…
