Spin excitations in the heavily overdoped monolayer graphene superconductor: an analog to the cuprates
Wei-Jie Lin, W. LiMing, Tao Zhou
Recently it was reported experimentally that the monolayer graphene can be doped to beyond the Van Hove singularity. We study theoretically the possible superconductivity and the c…
Chaos in the Fishnet
Robert de Mello Koch, W. LiMing, Hendrik J. R. Van Zyl +1
We consider the computation of out-of-time-ordered correlators (OTOCs) in the fishnet theories, with a mass term added. These fields theories are not unitary. We compute the growth…
The transport mechanism of the integer quantum Hall effect
W. LiMing, Tan Hui
The integer quantum Hall effect is analysed using a transport mechanism with a semi-classic wave packages of electrons in this paper. A strong magnetic field perpendicular to a sla…
Majorana zero modes on a 1D chain for quantum computation
Lei Chen, W. LiMing, Jia-Hui Huang
Numerical calculations for Majorana zero modes on a one-dimensional chain are performed using the technique of block diagonalization for general parameter settings. It is found tha…
The fermi arc and fermi pocket in cuprates in a short-range diagonal stripe phase
W. LiMing, Sha Ke, Jiayun Luo +2
In this paper we studied the fermi arc and the fermi pocket in cuprates in a short-range diagonal stripe phase with wave vectors , which reproduce with a high accurac…
Andreev reflection and tunneling spectrum in a superlattice of metal-superconductor junctions
W. LiMing, Jiayun Luo, Xiaoxue Cai +2
The tunneling spectrum of an electron and a hole in a superlattice of NS junctions is computed using the BTK approach and the transfer matrix method. It shows sharp resonances at s…
Andreev reflection and tunneling spectrum in metal-superconductor-metal junctions
W. LiMing, J. J. Ouyang, Liangbin Hu
The tunneling spectrum of an electron and a hole in metal-superconductor-metal junctions is computed using the Blonder-Tinkham-Klapwijk theory. The incident and the outgoing curren…
Repulsion and attraction in high Tc superconductors
W. LiMing, Haibo Chen, Liangbin Hu
The influence of repulsion and attraction in high-Tc superconductors to the gap functions is studied. A systematic method is proposed to compute the gap functions using the irreduc…
Spin density wave in oxypnictide superconductors in a three-band model
Mingsheng Long, Liangbin Hu, W. LiMing
The spin density wave and its temperature dependence in oxypnictide are studied in a three-band model. The spin susceptibilities with various interactions are calculated in the ran…
Gap symmetries from the neighbor coupling in square-lattice superconductors
W. Liming
The gap symmetries of superconductivity are studied in this work. It is found that the gap symmetries are simply determined by the 4-fold rotational symmetries of the coupling pote…
From Neel long-range order to spin-liquids in the multiple-spin exchange model
Weyls LiMing, Gregoire Misguich, Philippe Sindzingre +1
The phase diagram of the multiple-spin exchange model on the triangular lattice is studied using exact diagonalizations. The two-spin (J_2) and four-spin (J_4) exchanges have been…
