Field theoretical approach to spin models
Feng Liu, Zhenhao Fan, Zhipeng Sun +2
We developed a systematic non-perturbative method base on Dyson-Schwinger theory and the -derivable theory for Ising model at broken phase. Based on these methods, we obtain cri…
Modified Method in Electronic Systems
Zhipeng Sun, Zhenhao Fan, Hui Li +2
A modified approximation to many - body systems is developed. The approximation has the same computational complexity as the traditional approach, but uses a different tr…
Covariant Bethe-Salpeter approximation in strongly correlated electron systems model
Zhenhao Fan, Zhipeng Sun, Dingping Li +3
Strongly correlated electron systems are generally described by tight binding lattice Hamiltonians with strong local (on site) interactions, the most popular being the Hubbard mode…
Nonlinear Transport in a Two Dimensional Holographic Superconductor
Hua Bi Zeng, Yu Tian, Zhe Yong Fan +1
The problem of nonlinear transport in a two dimensional superconductor with an applied oscillating electric field is solved by the holographic method. The complex conductivity can…
d-wave Holographic Superconductor Vortex Lattice and Non-Abelian Holographic Superconductor Droplet
Hua-Bi Zeng, Zhe-Yong Fan, Hong-Shi Zong
A d-wave holographic superconductor is studied under a constant magnetic field by perturbation method, we obtain both droplet and triangular vortex lattice solution. The results ar…
Characteristic length of a Holographic Superconductor with -wave gap
Hua-Bi Zeng, Yu Jiang, Zhe-Yong Fan +1
After the discovery of the -wave and -wave holographic superconductors, holographic models of -wave superconductor have also been constructed recently. We study analytical…
Superconducting Coherence Length and Magnetic Penetration Depth of a p-wave Holographic Superconductor
Hua-Bi Zeng, Zhe-Yong Fan, Hong-Shi Zong
A classical SU(2) Einstein-Yang-Mills theory in 3+1 dimensional anti-de Sitter spacetime is believed to be dual to a p-wave superconductor in 2+1 dimensional flat spacetime. In ord…
