Effect of interactions in the interference pattern of Bose Einstein condensates
PHYSICAL REVIEW A(2020)
摘要
Understanding the effect of interactions in the phase evolution of expanding
atomic Bose Einstein condensates is fundamental to describe the basic
phenomenon of matter wave interference. Many theoretical and experimental works
tackled this problem, always with the implicit assumption that the mutual
interaction between two expanding condensates rigidly modifies the phase
evolution through an effective force. In this paper, we present a combined
experimental and theoretical investigation of the interference profile of
expanding ^87Rb condensates, with a specific focus on the effect of
interactions. We come to the different conclusion that the mutual interaction
produces local modifications of the condensate phase only in the region where
the wavepackets overlap.
