Absence of coherent peaks in a fractionalized BCS superconducting state
Yin Zhong, Han-Tao Lu, Hong-Gang Luo
We explore a fractionalized Bardeen-Cooper-Schrieffer (BCS) superconducting state, which is a minimal extension of usual BCS framework. It is found that this state has simi…
Topological quantum phase transition in Kane-Mele-Kondo lattice model
Yin Zhong, Yu-Feng Wang, Han-Tao Lu +1
We systematically explore the ground-state phase diagram of the Kane-Mele-Kondo lattice model on the honeycomb lattice, in particular, we focus on its magnetic properties which has…
Kondo spin liquid in Kondo necklace model: Classical disordered phase versus symmetry-protected topological state
Yin Zhong, Yu-Feng Wang, Han-Tao Lu +1
We study possible topological features of Kondo spin liquid phase in terms of the one- and two-dimensional Kondo necklace models within the frame work of quantum O(N) non-liner sig…
fractionalized Chern/topological insulators in an exactly soluble correlated model
Yin Zhong, Yu-Feng Wang, Hong-Gang Luo
In this paper we propose an exactly soluble model in two-dimensional honeycomb lattice, from which two phases are found. One is the usual Chern/topological insulating state and the…
Orthogonal Dirac semimetal on honeycomb lattice and the electron spectral function in orthogonal metallic states
Yin Zhong, Hong-Gang Luo
Recently, a concept of orthogonal metal has been introduced to reinterpret the disordered state of slave-spin representation in the Hubbard model as an exotic gapped metallic state…
