Stability of the Néel quantum critical point in the presence of Dirac fermions
Huanzhi Hu, Jennifer Lin, Mikolaj D. Uryszek +1
We investigate the stability of the Néel quantum critical point of two-dimensional quantum antiferromagnets, described by a non-linear model (NLM), in the presence of a Kond…
Interplay of interactions and disorder at the charge-density wave transition of two-dimensional Dirac semimetals
Mikolaj D. Uryszek, Frank Krüger
We consider the effects of weak quenched fermionic disorder on the quantum-phase transition between the Dirac semimetal and charge density wave (CDW) insulator in two spatial dimen…
Fermionic criticality of anisotropic nodal point semimetals away from the upper critical dimension: exact exponents
Mikolaj D. Uryszek, Frank Krüger, Elliot Christou
We consider the fermionic quantum criticality of anisotropic nodal point semimetals in spatial dimensions that disperse linearly in dimensions, and quadratica…
Quantum Criticality of Semi-Dirac Fermions in 2+1 Dimensions
Mikolaj D. Uryszek, Elliot Christou, Akbar Jaefari +2
Two-dimensional semi-Dirac fermions are quasiparticles that disperse linearly in one direction and quadratically in the other. We investigate instabilities of semi-Dirac fermions t…
