Critical structure and emergent symmetry of Dirac fermion systems
Jiang Zhou
Emergent symmetry in Dirac system means that the system acquires an enlargement of two basic symmetries at some special critical point. The continuous quantum criticality between t…
Fermionic criticality with enlarged fluctuations in Dirac semimetals
Jiang Zhou, Su-peng Kou
The fluctuations-driven continuous quantum criticality has sparked tremendous interest in condensed matter physics. It has been verified that the gapless fermions fluctuations can…
Critical behavior of QED--Gross-Neveu-Yukawa Theory in an Arbitrary Gauge
Jiang Zhou, Su-Peng Kou
The chiral QED--Gross-Neveu-Yukawa (QED-GNY) theory is a -dimensional U(1) gauge theory with flavors of four-component Dirac fermions coupled to a scalar field.…
Parity Anomaly of Lattice Maxwell Fermions in Two Spatial Dimensions
Jiang Zhou, Xiaosi Qi, Yajie Wu +1
Unconventional lattice fermions with high degeneracies beyond Weyl and Dirac fermions have attracted intensive attention in recent years. In this paper, attention is drawn to the p…
Duality of deconfined quantum critical point in two dimensional Dirac semimetals
Jiang Zhou, Ya-jie Wu, Su-Peng Kou
In this paper we discuss the Nel and Kekul valence bond solids quantum criticality in graphene Dirac semimetal. Considering the quartic four-fermion interacti…
Topological Mid-gap States of px+ipy Topological Superconductor with Vortex superlattice
Jiang Zhou, Shi-Zhu Wang, Ya-Jie Wu +2
In this paper, the px+ipy topological superconductor with vortex superlattice is studied. We found that there exist mid-gap energy bands induced by the vortex superlattice and the…
Quantum Phase Liquids-Fermionic Superfluid without Phase Coherence
Ya-Jie Wu, Jiang Zhou, Su-Peng Kou
We investigate the two dimensional generalized attractive Hubbard model in a bipartite lattice, and and a "quantum phase liquid" phase, in which the fermions are paired but don't h…
Strongly fluctuating fermionic superfluid in attractive π-flux Hubbard model
Ya-Jie Wu, Jiang Zhou, Su-Peng Kou
Ultracold atoms in optical lattice provides a platform to realize the superfluid (SF) state, a quantum order with paired charge-neutral fermions. In this paper, we studied SF state…
Topological Majorana Lattice Model: Induced "Topological Superconductor" on Topological Superconductor with Vortex-lattice
Jiang Zhou, Ya-Jie Wu, Rong-Wu Li +2
In this paper we study an s-wave topological SC with a square vortex-lattice. We proposed a topological Majorana lattice model to describe this topological state. We found that the…
