Resetting photons

Abstract Starting from a frequency diffusion process for tagged photon which simulates relaxation to the Planck law, we introduce resetting where photons lower their at random times. We consider two versions, one low is independent of existing and second case reduction in scales with original frequency. The result nonlinear Markov stationary distribution modifies law by abundance low-frequency occupation. physical relevance such processes can be found explorations nonequilibrium effects, e.g., via expansions confined plasma or gas strongly inelastic scattering matter.
