Interaction-Driven Metal-Insulator Transition in Strained Graphene
Interaction-Driven Metal-Insulator Transition in Strained Graphene
The question of whether electron-electron interactions can drive a metal to insulator transition in graphene under realistic experimental conditions is addressed. Using three representative methods to calculate the effective long-range Coulomb interaction between π electrons in graphene and solving for the ground state using quantum Monte Carlo methods, we argue …
