Parent-bilinear Sea-boson Correspondence with Spin

Abstract

This is a sort of tutorial where we present many of the tedious details involved in deriving the correspondence between the number conserving product of two fermi/bose fields with spin and the corresponding sea/condensate displacements also with spin. This time we include finite temperature effects differently by coupling the sea-bosons to an inhomogeneous chemical potential. It is shown that many of the salient features of the free theory are reproduced properly by this approach. An attempt is made to be as detailed as possible, this includes providing formulas for the sea-bosons as well as computing the finite temperature Fermi correlators.
