Nematic Quantum Criticality in Dirac Systems

Nematic Quantum Criticality in Dirac Systems

We investigate nematic quantum phase transitions in two different Dirac fermion models. The models feature twofold and fourfold, respectively, lattice rotational symmetries that are spontaneously broken in the ordered phase. Using negative-sign-free quantum Monte Carlo simulations and an ϵ-expansion...
