Twisted Bilayer Graphene Lifetimes At Integer Fillings: An Analytic Result
Haoyu Hu, Yuelin Shao, Lorenzo Crippa +5
Twisted bilayer graphene near integer fillings hosts correlated single-particle excitations whose dispersion and linewidth are increasingly accessible experimentally. We study thes…

Electromagnetic responses of bilayer excitonic insulators: from exciton London equations to dipole and inverse dipole Hall effects
Yuelin Shao, Hao Shi, Xi Dai
We develop a microscopic theory of the linear electromagnetic response of bilayer excitonic insulators relevant to electron-hole double-layer systems. Using a self-consistent Hartr…

Giant High-order Nonlinear and Nonreciprocal Electrical Transports Induced by Valley Flipping in Bernal Bilayer Graphene
Yuelin Shao, Xi Dai
We investigate the electrical transport properties of the mini-valley polarized state proposed recently in slightly doped Bernal Bilayer Graphene (BLG) in large electric displaceme…
