Effects of phase fluctuation on a mixture of rotating superfluids

  • 19 Accesses

Abstract

It is shown that if the root-mean-square of the gradient of the phase fluctuation of either of the components exceeds the corresponding inverse of the coherence length or if the chemical potential exceeds\(\bar W\) ρ 1 0 or\(\bar W\) ρ 2 0 , where\(\bar W\) is the volume integrals of the interaction function between the components, and ρ 1 0 , ρ 2 0 are the densities of the two components, the mixture of two rotating superfluids has an instability.
