Critical properties of the valence-bond-solid transition in lattice quantum electrodynamics
Nikolai Zerf, Rufus Boyack, Peter Marquard +2
Elucidating the phase diagram of lattice gauge theories with fermionic matter in 2+1 dimensions has become a problem of considerable interest in recent years, motivated by physical…
Fermion Traces Without Evanescence
Nikolai Zerf
We outline the evaluation of -dimensional fermion traces () built by products of Dirac- matrices suitable for a uniform dimensional continuation. Such a conti…
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…
Critical properties of the Néel/algebraic-spin-liquid transition
Nikolai Zerf, Rufus Boyack, Peter Marquard +2
The algebraic spin liquid is a long-sought-after phase of matter characterized by the absence of quasiparticle excitations, a low-energy description in terms of emergent Dirac ferm…
Critical behavior of the QED-Gross-Neveu-Yukawa model at four loops
Nikolai Zerf, Peter Marquard, Rufus Boyack +1
We study the universal critical properties of the QED-Gross-Neveu-Yukawa model with flavors of four-component Dirac fermions coupled to a real scalar order parameter at fou…
Transition between algebraic and quantum spin liquids at large
Rufus Boyack, Chien-Hung Lin, Nikolai Zerf +2
We present a field theory description of a quantum phase transition in two spatial dimensions between a algebraic spin liquid with flavors of gapless two-component Dirac…
