Abstract

The phase resolution limit of a Mach-Zehnder atom interferometer whose input consists of degenerate quantum gases of either bosons or fermions is analyzed. It is indicated that for degenerate gases, the number of atoms within one de Broglie wavelength is larger than unity, so that atom-atom interactions and quantum statistics are no longer negligible. It is shown that for equal atom numbers, the phase resolution achievable with fermions is noticeably better than for interacting bosons.
