Determinant Quantum-Quantum Monte Carlo: Coherent Auxiliary-Field Sampling
Xuepeng Wang, Sagnik Banerjee, Debanjan Chowdhury
We introduce determinant quantum-quantum Monte Carlo (DQMC), a quantum algorithm that lifts the auxiliary-field sampling and averaging at the operational core of determinant qu…
Intertwined Orders, Quantum Criticality and Skyrmions in Tunable Topological Bands
Xuepeng Wang, Johannes S. Hofmann, Debanjan Chowdhury
Skyrmions are emergent many-body excitations that lie at the heart of both multi-component quantum Hall-like systems and deconfined quantum criticality. In a companion article (X.…
Spin-Polaron Mediated Superconductivity in Doped Chern Antiferromagnets
Xuepeng Wang, J. F. Mendez-Valderrama, Johannes S. Hofmann +1
The study of interacting topological bands with a tunable bandwidth offers a unique platform to study the interplay of intertwined orders and emergent non-electronic excitations. H…
Low-energy optical absorption in correlated insulators: Projected sum rules and the role of quantum geometry
Dan Mao, Juan Felipe Mendez-Valderrama, Debanjan Chowdhury
Inspired by the discovery of a variety of correlated insulators in the moiré universe, controlled by interactions projected to a set of isolated bands with a narrow bandwidth, we e…
Correlated Topological Mixed-Valence Insulators in Moiré Hetero-Bilayers
Juan Felipe Mendez-Valderrama, Sunghoon Kim, Debanjan Chowdhury
Moiré transition metal dichalcogenide (TMD) materials provide an ideal playground for studying the combined interplay of strong interactions and band-topology over a range of elect…
Theory of Correlated Insulators and Superconductor at in Twisted WSe
Sunghoon Kim, Juan Felipe Mendez-Valderrama, Xuepeng Wang +1
The observation of a superconducting phase, an intertwined insulating phase, and a continuous transition between the two at a commensurate filling of in bilayers of twisted W…
