Some aspects of functional Bethe ansatz
You-Quan Li
The validity of Bethe ansatz wave function without the backward scattering for the problem of impurity in correlated hosts with periodic boundary condition is illustrated by a simp…
Theory of electrons with orbital degeneracy
You-Quan Li, U. Eckern
The Hubbard model for electrons with orbital degeneracy is shown to have an underlying SU_d(4) symmetry of spin-orbital double. A hidden charge SU_c(4) symmetry is exposed and an e…
Quantum Theory for Mesoscopic Electric Circuits and Its Applications
You-Quan Li, Bin Chen
This talk is assumed to exhibit an overview of the quantum theory for mesoscopic electric circuits and some of its further developments. In the theory the importance of the discret…
Thermodynamics of Kondo Model with Electronic Interactions
Shi-Jian Gu, You-Quan Li, Hai-Qing Lin
On the basis of Bethe ansatz solution of one dimensional Kondo model with electronic interaction, the thermodynamics equilibrium of the system in finite temperature is studied in t…
Ground State and Excitations of Spin Chain with Orbital Degeneracy
You-Quan Li, Micheal Ma, Da-Ning Shi +1
The one dimensional Heisenberg model in the presence of orbital degeneracy is studied at the SU(4) symmetric viewpoint by means of Bethe ansatz. Following Sutherland's previous wor…
