Abstract:We employ a dressed state approach to perform a study on the behavior of the
uncertainty principle for a system in a heated cavity. We find, in a small
cavity for a given temperature, an oscillatory behavior of the
momentum--coordinate product, $(\Delta\,p)\,(\Delta\,q)$, which attains
periodically finite absolute minimum (maximum) values, no matter large is the
elapsed time. This behavior is in a sharp contrast with what happens in free
space, in which case, the product $(\Delta\,p)\,(\Delta\,q)$ tends
asympt… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
