Abstract

In this work, we investigate the cumulative effects of laser and spin–orbit interaction (SOI) on the thermodynamic properties of a quantum pseudo-dot using the Tsallis formalism, through the evaluation of the energy to derive some thermodynamic properties at the accessible states. From the results obtained, we found that contrary to the SOI, a laser field is a suitable external field to reduce the rate of entropy (disorder) in a quantum system, and thus, this allows control on the spin alignment and increasing the number of accessible states hence stabilizing our system, simultaneously reducing the rate of entropy due to the great effect of the laser field. Therefore, the combined effects of laser field and SOI are an important parameter to enhance the thermodynamic quantities and more define the spin alignment of quantum system.
