Upper bounds on superconducting and excitonic phase-stiffness for interacting isolated narrow bands
Dan Mao, Debanjan Chowdhury
Inspired by the discovery of superconductivity in moiré materials with isolated narrow bandwidth electronic bands, here we analyze critically the question of what is the maximum at…
Fractionalization in Fractional Correlated Insulating States at filled twisted bilayer graphene
Dan Mao, Kevin Zhang, Eun-Ah Kim
Fractionalization without time-reversal symmetry breaking is a long-sought-after goal in the study of correlated phenomena. The earlier proposal of correlated insulating states at…
Diamagnetic response and phase stiffness for interacting isolated narrow bands
Dan Mao, Debanjan Chowdhury
A platform that serves as an ideal playground for realizing ``high'' temperature superconductors are materials where the electrons' kinetic energy is completely quenched, and inter…
Magnetically brightened dark electron-phonon bound states in a van der Waals antiferromagnet
Emre Ergeçen, Batyr Ilyas, Dan Mao +6
In van der Waals (vdW) materials, strong coupling between different degrees of freedom can hybridize elementary excitations into bound states with mixed character. Correctly identi…
Exciton-driven antiferromagnetic metal in a correlated van der Waals insulator
Carina A. Belvin, Edoardo Baldini, Ilkem Ozge Ozel +11
Collective excitations of bound electron-hole pairs -- known as excitons -- are ubiquitous in condensed matter, emerging in systems as diverse as band semiconductors, molecular cry…
Quasiperiodicity, band topology, and moiré graphene
Dan Mao, T. Senthil
A number of moiré graphene systems have nearly flat topological bands where electron motion is strongly correlated. Though microscopically these systems are only quasiperiodic, the…
