A second order expansion in the local limit theorem for a branching system of symmetric irreducible random walks
Zhi-qiang Gao
Consider a branching random walk, where the branching mechanism is governed by a Galton-Watson process, and the migration by a finite range symmetric irreducible random walk on the…
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…
Classification and Distinction of Possible Insulating Phases in Twisted Bilayer Graphene by Impurity Effects
Zhi-Qiang Gao, Fa Wang
In this work the effects of impurity in various insulating phases of the twisted bilayer graphene (TBG) are studied. The well-accepted continuum model\cite{b} is employed and the l…
Nodeless -Wave Superconducting Phases in Cuprates with BaCuO-Type Structure
Zhi-Qiang Gao, Kai-Wei Sun, Fa Wang
In this work zero-temperature phase diagrams of cuprates with BaCuO-type CuO chain structure is investigated. The projective symmetry group analysis is employed in the stro…
Effects of Defects in Superconducting Phase of Twisted Bilayer Graphene
Hui Yang, Zhi-Qiang Gao, Fa Wang
In this work the effects of defects in the superconducting phases of the twisted bilayer graphene (TBG) are investigated. A will-accepted low energy effective model and a non-magne…
