Strain-Controlled Magnetic Phase Transitions through Anisotropic Exchange Interactions: A Combined DFT and Monte Carlo Study
Sudip Mandal, Mihir Ranjan Sahoo, Kalpataru Pradhan
Epitaxial strain provides a powerful, non-chemical route to tune the properties of functional materials by manipulating the coupling between spin, charge, and lattice degrees of fr…
Impact of Random Bond Disorder on Quantum Skyrmions in a spin-half Quantum Heisenberg Model
Amit Kumar, Kalpataru Pradhan
We investigate the impact of random bond disorder on quantum skyrmions using a spin-half quantum Heisenberg model on the square lattice with Dzyaloshinskii-Moriya interaction, Heis…
Combine effect of site dilution and long-range interaction on magnetic and transport properties in the half-filled Hubbard model
Sudip Mandal, Sourav Chakraborty, Kalpataru Pradhan
We investigate the magnetotransport properties of a diluted half-filled one-band Hubbard model with second-nearest-neighbor hopping on a simple cubic lattice, aiming to explore the…
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…
