Geometric phases of mixed quantum states: A comparative study of interferometric and Uhlmann phases
Xu-Yang Hou, Xin Wang, Zheng Zhou +2
Two geometric phases of mixed quantum states, known as the interferometric phase and Uhlmann phase, are generalizations of the Berry phase of pure states. After reviewing the two g…
Uhlmann phase of coherent states and the Uhlmann-Berry correspondence
Xin Wang, Xu-Yang Hou, Zheng Zhou +2
We first compare the geometric frameworks behind the Uhlmann and Berry phases in a fiber-bundle language and then evaluate the Uhlmann phases of bosonic and fermionic coherent stat…
Generalizations of Berry phase and differentiation of purified state and thermal vacuum of mixed states
Xu-Yang Hou, Zi-Wen Huang, Zheng Zhou +3
Two representations of mixed states by state-vectors, known as purified state and thermal vacuum, have been realized on quantum computers. While the two representations look simila…
Machine learning of XY model on a spherical Fibonacci lattice
Chen-Hui Song, Qu-Cheng Gao, Xu-Yang Hou +5
We study the XY model on a spherical surface inspired by recently realized spherically confined atomic gases. Instead of a traditional latitude-longitude lattice, we introduce a mu…
