Bandos-Lechner-Sorokin-Townsend电动力学中的黑体辐射
Blackbody radiation in Bandos-Lechner-Sorokin-Townsend electrodynamics
摘要
Abstract
Bandos-Lechner-Sorokin-Townsend electrodynamics is a two-parameter extension of Maxwell electrodynamics.It unifies Born-Infeld and ModMax theories and satisfies electromagnetic duality.In this new electrodynamic theory,the dispersion relation of electromagnetic waves is examined in the presence of a strong magnetic background field.Based on this,thermodynamic quantities,such as the energy density and pressure of the photon gas,are calculated.It is discovered that the BLST theory provides a modification to the blackbody radiation spectrum,particularly to Stefan-Boltzmann law.As the dispersion relations are dependent on the direction of the background magnetic field,the blackbody radiation power is a function of the angle between the area element direction and background magnetic field direction.关键词
