Curvature-Induced Nonclassicality in a Generalized Jaynes-Cummings Model
Somayeh Kourkinejat, Ali Mahdifar, Ehsan Amooghorban
In this paper, we investigate the influence of spatial curvature on the Jaynes-Cummings model. We employ an analog model of general relativity, representing the field inside a cavi…

Effects of Spatial Curvature on Blackbody Radiation: Modifications to Energy Distribution and Fundamental Laws
Somayeh Kourkinejat, Ali Mahdifar, Ehsan Amooghorban
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…

Impact of spatial curvature on quantum Otto engines
S. Kourkinejat, A. Mahdifar, E. Amooghorban
In this paper, we consider a quantum Otto cycle with a quantum harmonic oscillator on a circle as its working substance. Since the eigen-energies of this oscillator depend on the c…
