Description
We study the finite temperature effects on the soft graviton theorem and the gravitational memory effect using the thermofield dynamics formalism. The soft factor depends on the nature of the scatterers at finite temperatures. Thus, the universal behaviour of the soft factor is lost. However, the universality in the scattering cross-section of the soft processes is observed at low temperatures. Further, we obtain the gravitational memory operator and its action on the asymptotic out-state using the soft graviton theorem. We observed that the memory effect depends on the nature of the particles responsible for the gravitational radiation at finite temperatures. The soft graviton theorem and the gravitational memory effect at finite temperatures are consistent with their zero-temperature counterparts.
