Infinite bound states and energy spectrum induced by a Coulomb-like potential of type III in a flat band system
Yi-Cai Zhang
In this work, we investigate the bound states in a one-dimensional spin-1 flat band system with a Coulomb-like potential of type III, which has a unique non-vanishing matrix elemen…
Infinite bound states and hydrogen atom-like energy spectrum induced by a flat band
Yi-Cai Zhang, Guo-Bao Guo
In this work, we investigate the bound state problem in one dimensional spin-1 Dirac Hamiltonian with a flat band. It is found that, the flat band has significant effects on the bo…
Lyapunov exponent, mobility edges, and critical region in the generalized Aubry-Andre model with an unbounded quasiperiodic potential
Yi-Cai Zhang, Yan-Yang Zhang
In this work, we investigate the Anderson localization problems of the generalized Aubry-André model (Ganeshan-Pixley-Das Sarma's model) with an unbounded quasi-periodic potential…
Collective excitations in two-dimensional SU() Fermi gases with tunable spin
Chengdong He, Zejian Ren, Bo Song +5
We measure collective excitations of a harmonically trapped two-dimensional (2D) SU() Fermi gas of Yb confined to a stack of layers formed by a one-dimensional optical l…
Two-fluid theory for superfluid system with anisotropic effective masses
Yi-Cai Zhang, Chao-Fei Liu, Bao Xu +2
In this work, we generalize the two-fluid theory to a superfluid system with anisotropic effective masses along different principal axis directions. As a specific example, such a t…
