Abstract

This paper compared the results of Gaussian, Shannon, and Tsallis entropies in the study of the decoherence of magnetopolaron in nanostructures in the presence of an electric field. The unitary transformation and linear combination method are used to derive the energy spectrum of the magnetopolaron in Gaussian and asymmetric quantum dot. Results suggest that Shannon entropy is suitable for the faster transmission of information about the system. With the increase in the strength of electric field and cyclotron frequency, the collapse revival in entropy is observed. With the asymmetric quantum dot, one realizes that the amount of information indicated by Shannon entropy is efficient than with other entropies. With the enhancement of the electric field strength, the entropies evolve as a wave envelop, and the information is transmitted as a wave bundle.
