Response of perturbed spherium to external fields
We study the spectra and response of two electrons moving on a surface of a sphere and interacting via harmonic potential, to external static and laser fields. The spectrum of such system law is analysed in the light of varying coupling strength. In addition, the expectation value of cosine of the angle between external field and the system for first and second order have been evaluated and analysed.
