Theoretical study of phonon-mediated superconductivity beyond Migdal-Eliashberg approximation and Coulomb pseudopotential
Jie Huang, Zhao-Kun Yang, Xiao-Yin Pan +1
In previous theoretical studies of phonon-mediated superconductors, the electron-phonon coupling is treated by solving the Migdal-Eliashberg equations under the bare vertex approxi…
Electronic structure and spin-lattice relaxation in superconducting vortex states on the kagome lattice near van Hove filling
Hong-Min Jiang, Shun-Li Yu, Xiao-Yin Pan
Starting from a tight-binding model on the kagome lattice near the van Hove filling, the superconducting (SC) properties are investigated self-consistently using the Bogoliubov-de…
Local breaking of the spin degeneracy in the vortex states of Ising superconductors: Induced antiphase ferromagnetic order
Hong-Min Jiang, Xiao-Yin Pan
Ising spin-orbital coupling is usually easy to identify in the Ising superconductors via an in-plane critical field enhancement, but we show that the Ising spin-orbital coupling al…
A non-perturbative study of the interplay between electron-phonon interaction and Coulomb interaction in undoped graphene
Zhao-Kun Yang, Xiao-Yin Pan, Guo-Zhu Liu
In condensed-matter systems, electrons are subjected to two different interactions under certain conditions. Even if both interactions are weak, it is difficult to perform perturba…
Fermion dispersion renormalization in a two-dimensional semi-Dirac semimetal
Hao-Fu Zhu, Xiao-Yin Pan, Guo-Zhu Liu
We present a non-perturbative study of the quantum many-body effects caused by the long-range Coulomb interaction in a two-dimensional semi-Dirac semimetal. This kind of semimetal…
On the gauge transformation for the rotation of the singular string in the Dirac monopole theory
Xiao-Yin Pan, Yin Chen, Yu-Qi Li +2
In the Dirac theory of the quantum-mechanical interaction of a magnetic monopole and an electric charge, the vector potential is singular from the origin to infinity along certain…
