Three-dimensional Foliated Fractional Quantum Hall Phases
Sahana Das, Navketan Batra, Andrea Kouta Dagnino +4
Foliated topological orders in three dimensions are layered systems in which anyons are free to move within a layer but cannot hop between them. A simple model with such a phase is…
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…
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…
Low-energy optical sum-rule in moiré graphene
J. F. Mendez-Valderrama, Dan Mao, Debanjan Chowdhury
Few layers of graphene at small twist-angles have emerged as a fascinating platform for studying the problem of strong interactions in regimes with a nearly quenched single-particl…
