Abstract

Description

We propose a new method for detecting paired states in either bosonic or fermionic systems using interference experiments with independent or weakly coupled low dimensional systems. We demonstrate that our method can be used to detect both the FFLO and the d-wave paired states of fermions, as well as quasicondensates of singlet pairs for polar F=1 atoms in two dimensional systems. We discuss how this method can be used to perform phase-sensitive determination of the symmetry of the pairing amplitude.
