Contribution

It explores the effects of Podolsky's second-order, gauge-invariant extension on fundamental electromagnetic phenomena at finite temperature and spatial confinement.

Findings

Podolsky modification alters the Stefan-Boltzmann law.

Podolsky theory impacts the Casimir effect under confinement.

Thermo Field Dynamics effectively models these effects.

Abstract

In this work, Podolsky theory, a second-order, Lorentz- and gauge-invariant extension of classical electrodynamics, is considered. The effects of Podolsky's modification on fundamental phenomena such as the Stefan-Boltzmann law and the Casimir effect for the electromagnetic field are investigated. The Thermo Field Dynamics (TFD) formalism is employed to describe quantum fields at finite temperature and under spatial confinement through its topological structure.
