The ability to tune magnetic orders, such as magnetic anisotropy and topological spin texture, is desired to achieve high-performance spintronic devices. A recent strategy has been to employExpand
Strain-induced superconductor-insulator transition on a Lieb lattice
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 show that in twoExpand
Mott Transition and Anomalous Resistive State in the Pyrochlore Molybdates
The rare-earth based pyrochlore molybdates involve orbitally degenerate electrons Hund's coupled to local moments. The large Hund's coupling promotes ferromagnetism, the superexchange between theExpand
Ground State of the Two Orbital Hubbard Model on the Pyrochlore Lattice with Competing Double Exchange and Superexchange Interactions
The two orbital Hubbard model, with the electrons additionally coupled to a complex magnetic background, arises in the pyrochlore molybdates. The background involves local moments Hund's coupled toExpand
Skyrmions drive topological Hall effect in a Shastry-Sutherland magnet
The Shastry-Sutherland model and its generalizations have been shown to capture emergent complex magnetic properties from geometric frustration in several quasi-two-dimensional quantum magnets. UsingExpand
Topological Hall effect in the Shastry-Sutherland lattice
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 external magneticExpand
Complex magnetic ordering and associated topological Hall effect in a two-dimensional metallic chiral magnet
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 system, we haveExpand
Transport and spectroscopic signatures of a disorder stabilized metal in two-dimensional frustrated Mott insulators
We report the first non perturbative study of disorder induced insulator-metal transition at half filling in a geometrically frustrated triangular lattice Mott insulator. Our numerical approachExpand
