THE NORMALIZED EMISSION SPECTRUM OF THE EFFECTIVE ATOM-PHOTON-MAGNON SYSTEM

ABSTRACT
This paper explores the behaviour of the normalized emission spectrum within the confines of the atom-photon-magnon regime at its dispersive limit, with a focus on its dependency on various parameters and initial conditions. The investigation reveals several significant findings. Firstly, regarding the mixing angle and detuning, minimal variation in the spectrum is observed with small detuning values, although the influence of the mixing angle becomes more pronounced for the initial squeezed coherent and initial binomial states, particularly notable in the case of the squeezed coherent state. Secondly, concerning the initial state strength, an increase in strength results in a gradual decrease in the spectrum across all states except the binomial state, which finally experiences an increase. However, the squeezed coherent state displays a gradual decay without reaching zero, whereas the thermal state decays completely. Lastly, concerning magnoncavity coupling, stronger coupling between magnon-and cavity causes a shift in the spectrum towards higher positive detuning, with a more pronounced shift observed in the squeezed coherent state compared to other states.
