Critical Property of Geometric Phase in the Dicke Model
Gang Chen, Juqi Li, J. -Q. Liang
We obtain the ground-state energy level and associated geometric phase in the Dicke model analytically by means of the Holstein-Primakoff transformation and the boson expansion app…
Quantum Phase Transition in Finite-Size Lipkin-Meshkov-Glick Model
Gang Chen, J. -Q. Liang
Lipkin model of arbitrary particle-number N is studied in terms of exact differential-operator representation of spin-operators from which we obtain the low-lying energy spectrum w…
On the Origin of the Tunneling Asymmetry in the Cuprate Superconductors: a variational perspective
Hong-Yu Yang, Fan Yang, Yong-Jin Jiang +1
Through variational Monte Carlo calculation on Gutzwiller projected wave functions, we study the quasiparticle(qp) weight for adding and removing an electron from a high temperatur…
Kinetic magnetoelectric effect in a 2D semiconductor strip due to boundary-confinement induced spin-orbit coupling
Yongjin Jiang, Liangbin Hu
In a thin strip of a two-dimensional semiconductor electronic system, spin-orbit coupling may be induced near both edges of the strip due to the substantial spatial variation of th…
