Abstract:We define the characteristic temperature T C of a material by using the behaviour of the specific heat in the vicinity of this temperature: C p,N ðT Þ ¼ fð1 À ðT=T C Þ, p, N Þ for T 5 T C and C p,N ðT Þ ¼ gððT=T C Þ À 1, p, N Þ for T 4 T C where p is the external pressure and N is the number of particles. The characteristic temperature T C ¼ T C ( p, N ) can e.g. be identified with the transition temperature in the case of continuous phase transitions or with one of the two characteristic temperatures T ð1Þ C … 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.
