Transport 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…
Microscopic study of interlayer magnetic coupling across the interface in antiferromagnetic bilayers
Sandip Halder, Sudip Mandal, Kalpataru Pradhan
The enhancement of Neel temperature () of low- antiferromagnets in antiferromagnetic bilayers AF1/AF2, where the of AF1 is larger than AF2 (for example enhancemen…
Layer Resolved Magnetotransport Properties in Antiferromagnetic/Paramagnetic Superlattices
Sandip Halder, Sourav Chakraborty, Kalpataru Pradhan
We investigate the layer resolved magnetotransport properties of the antiferromagnetic/paramagnetic superlattices based on one band half-filled Hubbard model in three dimensions. I…
Magnetotransport Properties of Ferromagnetic/Antiferromagnetic Superlattices: Probing the role of induced magnetization in antiferromagnetic layer
Sandip Halder, Snehal Mandal, Kalpataru Pradhan
We investigate the magnetic and transport properties of the (LSMO)/ (PCMO) like ferromagnetic/antiferromagnetic superlattices in thre…
