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…
Optical properties of monoclinic HfO2 studied by first-principles local density approximation +U approach
Jinping Li, Jiecai Han, Songhe Meng +2
The band structures and optical properties of monoclinic HfO2 are investigated by the local density approximation (LDA)+U approach. With the on-site Coulomb interaction being intro…
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…
First-principles generalized gradient approximation (GGA) +Ud+Up studies of electronic structures and optical properties in cubic HfO2
Jinping Li, Songhe Meng, Lingling Li +2
The electronic structures and optical properties of cubic HfO2 are calculated by means of generalized gradient approximation (GGA) +U approach. Without on-site Coulomb interactions…
Double-Pulse Deexcitations in a One-Dimensional Strongly Correlated System
Hantao Lu, Janez Bonca, Takami Tohyama
We investigate the ultrafast optical response of the one-dimensional half-filled extended Hubbard model exposed to two successive laser pulses. By using the time-dependent Lanczos…
