Magnetic-field-induced nontrivial electronic state in the Kondo-lattice semimetal CeSb
Y. Fang, F. Tang, Y. R. Ruan +10
Synergic effect of electronic correlation and spin-orbit coupling is an emerging topic in topological materials. Central to this rapidly developing area are the prototypes of stron…
On an exactly solvable toy model and its dynamics
K. L. Yang, J. M. Zhang
The eigenstates and eigenenergies of a toy model, which arose in idealizing a local quenched tight-binding model in a previous publication [Zhang and Yang, EPL 114, 60001 (2016)],…
Bound states in the one-dimensional two-particle Hubbard model with an impurity
J. M. Zhang, Daniel Braak, Marcus Kollar
We investigate bound states in the one-dimensional two-particle Bose-Hubbard model with an attractive () impurity potential. This is a one-dimensional, discrete analogy of th…
Quantum quench dynamics of the Bose-Hubbard model at finite temperatures
J. M. Zhang, C. Shen, W. M. Liu
We study quench dynamics of the Bose-Hubbard model by exact diagonalization. Initially the system is at thermal equilibrium and of a finite temperature. The system is then quenched…
Exact diagonalization: the Bose-Hubbard model as an example
J. M. Zhang, R. X. Dong
We take the Bose-Hubbard model to illustrate exact diagonalization techniques in a pedagogical way. We follow the road of first generating all the basis vectors, then setting up th…
Nonlinear dynamics of a cigar-shaped Bose-Einstein condensate coupled with a single cavity mode
J. M. Zhang, F. C. Cui, D. L. Zhou +1
We investigate the nonlinear dynamics of a combined system which is composed of a cigar-shaped Bose-Einstein condensate and an optical cavity. The two sides couple dispersively. Th…
