Relativistic Mott transition and high-order van Hove singularity in twisted double bilayer WSe: mean-field and functional renormalization group study
Bilal Hawashin, Julian Kleeschulte, David Kurz +2
Experiments on twisted double bilayer tungsten diselenide have demonstrated that moir'e semiconductors can realize a relativistic Mott transition, i.e., a quantum phase transition…
Spontaneous Space-Time Parity Breaking Without Thermal Restoration
Bilal Hawashin, Michael M. Scherer, Michael Smolkin +1
We construct an ultraviolet-complete, local, and unitary quantum field theory in 2+1 dimensions that exhibits spontaneous breaking of space-time parity, persisting to arbitrarily h…
Quantum multicriticality and emergent symmetry in Dirac systems with two order parameters at three-loop order
Max Uetrecht, Igor F. Herbut, Michael M. Scherer +2
Two-dimensional materials with interacting Dirac excitations can host quantum multicritical behavior near the phase boundaries of the semimetallic and two-ordered phases. We study…
Gross-Neveu-XY quantum criticality in moiré Dirac materials
Bilal Hawashin, Michael M. Scherer, Lukas Janssen
Two-dimensional van-der-Waals materials offer a highly tunable platform for engineering electronic band structures and interactions. By employing techniques such as twisting, gatin…
