Nonsmooth and level-resolved dynamics illustrated with the tight binding model
J. M. Zhang, Masudul Haque
We point out that in the first order time-dependent perturbation theory, the transition probability may behave nonsmoothly in time and have kinks periodically. Moreover, the detail…

Integrability and weak diffraction in a two-particle Bose-Hubbard model
Daniel Braak, J. M. Zhang, Marcus Kollar
A recently introduced one-dimensional two-particle Bose-Hubbard model with a single impurity is studied on finite lattices. The model possesses a discrete reflection symmetry and w…
