Dual-temperature acceleration radiation

TL;DR

This paper introduces an analytical model for a system emitting acceleration radiation at two distinct temperatures, revealing equilibrium states with both thermal and non-thermal characteristics, useful for studying vacuum acceleration phenomena.

Contribution

It provides a simple, solvable model for dual-temperature acceleration radiation with explicit spectral solutions, advancing understanding of non-thermal vacuum radiation in complex states.

Findings

Equilibrium states follow Planck distributions asymptotically.

Transition between thermal and non-thermal radiation is characterized.

Analytical solutions for the radiation spectrum are obtained.

Abstract

We solve for a system that emits acceleration radiation at two different temperatures. The equilibrium states occur asymptotically in Planck distributions and transition non-thermally. The model is simple enough to obtain a global solution for the radiation spectrum analytically. We present it as a potentially useful model for investigation of non-thermal vacuum acceleration radiation in the presence of final(initial) asymptotic thermodynamic horizon(less) states in equilibrium.
