abstract
In this paper, we investigate the effects of spatial curvature on blackbody radiation. By employing an analog model of general relativity, we replace the conventional straight-line harmonic oscillators used to model blackbody radiation with oscillators on a circle. This innovative approach provides an effective framework for describing blackbody radiation influenced by spatial curvature. We derive the curvature-dependent Planck energy distribution and find that moving from flat to curved space results in a reduction in both the height and width of the Planck function. Moreover, increasing the curvature leads to a pronounced redshift in the peak frequency. We also analyze the influence of spatial curvature on the Stefan-Boltzmann law, Rayleigh-Jeans law, and Wien law.

Curvature-Induced Nonclassicality in a Generalized Jaynes-Cummings Model
Replacing flat-space cavity operators with circle-oscillator operators, the paper shows that increased curvature shortens revival times and suppresses nonclassicality in a generalized Jaynes-Cummings model.
