Matter-Wave Phase Operators for Quantum Atom Optics: on the Possibility of Experimental Verification

EasyChair Preprint no. 5029

Abstract

In early 90’s Mandel and coworkers performed an experiment [1] to examine the significance of quantum phase operators by measuring the phase between two optical fields. We show that this type of quantum mechanical phase measurement is possible for matter-waves of ultracold atoms in a double well. In the limit of low number of atoms quantum and classical phases are drastically different. However, in the large particle number limit, they are quite similar. We assert that the matter-wave counterpart of the experiment [1] is realizable with the evolving technology of atom optics.

Keyphrases: Double well, matter-wave interferometry, Phase operators
