The Effects of Inter-Valley Coupling of Dirac Fermions near Four Dimensions
S. Thiagarajan, F. Krüger
We analyze the criticality of an Ising Gross-Neveu-Yukawa (GNY) theory of Dirac fermion valleys with intra- and inter-valley interactions, using a renormalization-group analy…

Nature of Topological Phase Transition of Kitaev Quantum Spin Liquids
Huanzhi Hu, Frank Krüger
We investigate the nature of the topological quantum phase transition between the gapless and gapped Kitaev quantum spin liquid phases away from the exactly solvable point. The tra…

Majorana Fermion Mean-Field Theories of Kitaev Quantum Spin Liquids
Shahnam Ghanbari Saheli, Jennifer Lin, Huanzhi Hu +1
We determine the phase diagrams of anisotropic Kitaev-Heisenberg models on the honeycomb lattice using parton mean-field theories based on different Majorana fermion representation…
