Interaction-induced nematic Dirac semimetal from quadratic band touching: A constrained-path quantum Monte Carlo study
Zi Hong Liu, Hongyu Lu, Zi Yang Meng +1
Electronic systems with quadratic band touchings, commonly found in two- and three-dimensional materials such as Bernal-stacked bilayer graphene, kagome metals, HgTe, and pyrochlor…

Emergent relativistic symmetry from interacting fermions on the honeycomb bilayer
Zi Hong Liu, Lukas Janssen
We study the phase diagram of interacting spinless fermions on the honeycomb bilayer at charge neutrality using large-scale quantum Monte Carlo simulations. In the noninteracting l…
