Description

We develop a Heat-kernel based formalism to compute the one-loop thermal effective action relevant for dimensionally reduced 3D Thermal EFT matching. Using this framework, we derive the effective operator basis up to dimension six for the Abelian Higgs model, incorporating the non-perturbative effects of the Polyakov loop, which plays a crucial role in shaping the thermal potential. We discuss the broader implications of these thermal effective operators for physical processes, including the nature of cosmological phase transitions and the resulting gravitational wave spectrum.
