Description

A Dyson boson realization for two-quasiparticle operators at finite temperature is derived by using the thermo field dynamic formalism. The operators of the finite temperature random phase approximation (FT-RPA) are constructed from the zero temperature two-quasiparticle operators. The conditions are found under which these thermal RPA quadrupole operators close the SU(6) algebra. The fulfillment of the SU(6) enforcing conditions at finite temperature is discussed. (orig.)
