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…

Finite-temperature topological phase transitions of spin- systems in Uhlmann processes: General formalism and experimental protocols

Xu-Yang Hou, Hao Guo, Chih-Chun Chien

The Uhlmann process is built on the density matrix of a mixed quantum state and offers a way to characterize topological properties at finite temperatures. We analyze an ideal spin…
