Identifying quantum phase transitions via geometric measures of nonclassicality

10 Mar 2020 Tan Kok Chuan

In this article, we provide theoretical support for the use of geometric measures of nonclassicality as a general tool to identify quantum phase transitions. We argue that divergences in the susceptibility of any geometric measure of nonclassicality are sufficient conditions to identify phase transitions at arbitrary temperature... (read more)
