Monte Carlo Studies of Twisted Bilayer Graphene: Strain and Thermal Fluctuations
Johannes S. Hofmann, Patrick Ledwith, Ashvin Vishwanath +2
We study the phase diagram of twisted bilayer graphene at charge neutrality as a function of twist angle , uniaxial heterostrain , and temperature using sign-p…

Symmetry protected topological phases under decoherence
Jong Yeon Lee, Yi-Zhuang You, Cenke Xu
We study ensembles described by density matrices with potentially nontrivial topological features. In particular, we study a class of symmetry protected topological (SPT) phases un…
