Projective phase measurements in one-dimensional Bose gases

Abstract:

We consider time-of-flight measurements in split one-dimensional Bose gases. It is well known that the low-energy sector of such systems can be described in terms of two compact phase fields ^ϕa,s(x). Building on existing results in the literature we discuss how a single projective measurement of the particle density after trap release is in a certain limit related to the eigenvalues of the vertex operator ei^ϕa(x). We emphasize the theoretical assumptions underlying the analysis of "single-s...
