Fractionalized quantum criticality in spin-orbital liquids from field theory beyond the leading order
Shouryya Ray, Bernhard Ihrig, Daniel Kruti +3
Two-dimensional spin-orbital magnets with strong exchange frustration have recently been predicted to facilitate the realization of a quantum critical point in the Gross-Neveu-SO(3…
Abelian Higgs model at four loops, fixed-point collision and deconfined criticality
Bernhard Ihrig, Nikolai Zerf, Peter Marquard +2
The abelian Higgs model is the textbook example for the superconducting transition and the Anderson-Higgs mechanism, and has become pivotal in the description of deconfined quantum…
Deconfined criticality from the QED-Gross-Neveu model at three loops
Bernhard Ihrig, Lukas Janssen, Luminita N. Mihaila +1
The QED-Gross-Neveu model is a (2+1)-dimensional U(1) gauge theory involving Dirac fermions and a critical real scalar field. This theory has recently been argued to represent…
Critical behavior of Dirac fermions from perturbative renormalization
Bernhard Ihrig, Luminita N. Mihaila, Michael M. Scherer
Gapless Dirac fermions appear as quasiparticle excitations in various condensed-matter systems. They feature quantum critical points with critical behavior in the 2+1 dimensional G…
Gross-Neveu-Yukawa model at three loops and Ising critical behavior of Dirac systems
Luminita N. Mihaila, Nikolai Zerf, Bernhard Ihrig +2
Dirac and Weyl fermions appear as quasi-particle excitations in many different condensed-matter systems. They display various quantum transitions which represent unconventional uni…
