Current work focuses on realizing how the interaction between binding energy(BE) and noise influences the magnetic susceptibility(χ) of doped GaAs quantum dot (QD). The system is exposed to Gaussian white noise and the dopant is also characterized by a Gaussian function. The work also highlights the role of the pathway via which noise may operate in the system. We have found that it is the multiplicative noise that alters the χ profile significantly from that of a noise-free atmosphere. However, additive noise does not change the χ profile from that under noise-free state to any meaningful size. Often multiplicative noise induces paramagnetism in the system which otherwise shows diamagnetism. And the noise-BE interplay prominently determines the extent of diamagnetism displayed by the system.
