All-temperature superfluidity in two dimensions
Bilal Hawashin, Soumyadeep Chaudhuri, Igor F. Herbut +1
In local theories with short-range interactions, continuous symmetries cannot be spontaneously broken in two spatial dimensions at nonzero temperature. -symmetric mo…
Quantum critical fan and emergent relativistic symmetry of two-dimensional Dirac semimetals
Friederike Ihssen, Bilal Hawashin, Mireia Tolosa-Simeón +1
Two-dimensional Dirac semimetals near a quantum critical point can be described by Gross--Neveu--Yukawa models. In view of recent experimental advances exhibiting a transition from…
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…
The Nordic-walking mechanism and its explanation of deconfined pseudocriticality from Wess-Zumino-Witten theory
Bilal Hawashin, Astrid Eichhorn, Lukas Janssen +2
The understanding of phenomena falling outside the Ginzburg-Landau paradigm of phase transitions represents a key challenge in condensed matter physics. A famous class of examples…
