Atomic scale skyrmions and large topological Hall effect in a breathing-kagome lattice
Nyayabanta Swain, Munir Shahzad, Pinaki Sengupta
Motivated by recent experiments in GdRuAl, we demonstrate the emergence of atomic scale Skyrmions in interacting spins on a breathing kagome lattice with competing n…
Complex magnetic ordering and associated topological Hall effect in a two-dimensional metallic chiral magnet
Nyayabanta Swain, Munir Shahzad, Pinaki Sengupta
Motivated by recent experiments on the observation of room temperature skyrmions in a layered heterostructure and subsequent demonstration of topological Hall effect in the same sy…
Topological Hall effect in the Shastry-Sutherland lattice
Munir Shahzad, Nyayabanta Swain, Pinaki Sengupta
We study the classical Heisenberg model on the geometrically frustrated Shastry-Sutherland (SS) lattice with additional Dzyaloshinskii-Moriya (DM) interaction in the presence of an…
Strain induced superconductor-insulator transition on Lieb lattice
Nyayabanta Swain, Madhuparna Karmakar
We report the numerical investigation of strain induced superconductor-insulator quantum phase transition on a Lieb lattice. Based on a non perturbative Monte Carlo technique, we s…
