αxx, αyy, αxy andαyx), first nonlinear (βxxx, βyyy, βxyy andβyxx), and second nonlinear (γxxxx, γyyyy, γxxyyandγyyxx)
polarizabilities of quantum dots under the influence of external pulsed field.
Simultaneous presence of additive white noise has also been considered. The
quantum dot contains dopant described by a Gaussian potential. The numbers of
pulse and the dopant location have been found to fabricate the said profiles
jointly. The β components display greater complexity in their
profiles in comparison with the α and γ counterparts. The presence of noise
prominently enhances the influence of dopant coordinate on the polarizability
profiles, particularly for α and γ components. However,
for β components, the said influence becomes quite
evident both in the presence and absence of additive noise. The study reveals
some means of achieving stable, enhanced, and often maximized output of
noise-driven linear and nonlinear polarizabilities.
