In the present investigation, the Shannon entropy‐based magnetocaloric effect (MCE) of GaAs quantum dot (QD) is explored under the simultaneous influence of anharmonicity and Gaussian white noise (GWHN). The symmetry of the anharmonic potential (AHP), the manner of incorporation of GWHN, and the QD confinement interplay with great intricacy to tailor the MCE. AHP of odd (even) symmetry reduces (increases) the confinement of the system relative to the anharmonicity‐free system. Generally, the MCE profiles behave in diverse manner under additive white noise and multiplicative white noise and often show deviation from the noise‐free condition. It is also found that additive (multiplicative) noise lowers (raises) the magnitude of MCE in comparison with the noise‐free values.

Current inspection strives to perform a detailed elaboration of the Tsallis entropy‐based magnetocaloric effect (MCE) of GaAs quantum dot (QD) doped with Gaussian impurity and under applied Gaussian white noise. Noise takes additive and multiplicative pathways for its entry to the doped QD. MCE has been found to decrease following the enhancement of temperature. The enquiry manifests magnetic field‐induced confinement and consequent decline in the disorder of the system during the gradual variation of several physical parameters. However, harnessing the extent of above confinement involves extremely sensitive and delicate control over the resultant influence of the particular physical parameter undergoing change, its range of magnitude, application of noise and its mode of inclusion. Importantly, MCE has been found to maximize only during the change in the strength of the dopant potential under multiplicative noise. And, on most occasions, multiplicative noise profoundly raises the MCE over its value under the state devoid of noise and under additive noise.
