Bound-like State in a 1D Self-Similar Delta-Barrier Array
Jia-Chen Tang, Xu-Yang Hou, Yan He +1
We investigate a one-dimensional quantum system with a self-similar arrangement of delta-function potential barriers, exhibiting discrete scale invariance. The singular potential i…

Mixed-state geometric phases of coherent and squeezed spin states
Xin Wang, Jia-Chen Tang, Xu-Yang Hou +2
Two mixed-state geometric phases, known as the Uhlmann phase and interferometric geometric phase (IGP), of spin coherent states (CSSs) and spin squeezed states (SSSs) are analyzed.…
