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…
Intertwined Magnetism and Superconductivity in Isolated Correlated Flat Bands
Xuepeng Wang, J. F. Mendez-Valderrama, Johannes S. Hofmann +1
Multi-orbital electronic models hosting a non-trivial band-topology in the regime of strong electronic interactions are an ideal playground for exploring a host of complex phenomen…
Quasicrystalline Spin Liquid
Sunghoon Kim, Mohammad Saad, Dan Mao +2
The interplay of electronic interactions and frustration in crystalline systems leads to a panoply of correlated phases, including exotic Mott insulators with non-trivial patterns…
