Abstract
A new master equation performing isotropic phase number squeezing is s uggested. The phase properties of coherent superpositions are analysed when the state evolves in the presence of a bath with fluctuations sq ueezed in this isotropic way. We find that such a reservoir greatly im proves the persistence of coherence with respect to either a customary thermal bath, or to an anisotropically squeezed phase-sensitive bath.
