Particle-hole asymmetric phases in doped twisted bilayer graphene

Autor: Hou, Run, Sur, Shouvik, Wagner, Lucas K., Nevidomskyy, Andriy H.

Despite much theoretical work, developing a comprehensive ab initio model for twisted bilayer graphene (TBG) has proven challenging due to the inherent trade-off between accurately describing the band structure and incorporating the interactions with

A major hurdle in understanding the phase diagram of twisted bilayer graphene (TBLG) are the roles of lattice relaxation and electronic structure on isolated band flattening near magic twist angles. In this work, the authors develop an accurate local
