Construction of symmetry in a Hubbard-type model
Zhi-Qiang Gao, Congjun Wu
As the smallest exceptional Lie group and the automorphism group of the non-associative algebra octonions, is often employed for describing exotic symmetry structures. We con…
Frustrated superconductivity and sextetting order
Zhiming Pan, Chen Lu, Fan Yang +1
The superconducting state typically favors a uniform spatial distribution akin to ferromagnetism. Nevertheless, the pair-density-wave state exhibits sign changes in the pairing ord…
Mott insulating states of the anisotropic SU(4) Dirac fermions
Han Xu, Yu Wang, Zhichao Zhou +1
We employ the large-scale quantum Monte-Carlo simulations to investigate the Mott-insulating states of the half-filled SU(4) Hubbard model on the square lattice with a staggered-fl…
Interlayer Coupling Driven High-Temperature Superconductivity in LaNiO Under Pressure
Chen Lu, Zhiming Pan, Fan Yang +1
The newly discovered high-temperature superconductivity in LaNiO under pressure has attracted a great deal of attentions. The essential ingredient characterizing the el…
