“…9,10 The energy utilization in modern solar cell photovoltaics and optoelectronic devices based on the excitonic energy transfer establishes distinct differences with the traditional charge carrier transfer. [10][11][12][13] Recently, the excitonic physics has emerged also in quantum information science. 14,15 Being the neutral particles, the excitons cannot move under the influence of the electric field potential; meanwhile, the controlling of excitons could open new perspectives for the replacement of traditional transistors and enable a new way of data communication and processing within especially designed quantum circuit.…”

We have studied the electron–electron interactions in the system composed of two metallic one-dimensional point contact and zero-sized wires, in the applied electric field and exposed to the influence of the external Zeeman magnetic field. The interactions between the electrons within wires have been taken into account within the usual Hubbard model. We have considered different limits of particle-filling on the atomic lattice site positions. We show the existence of the excitonic pairing in this one-dimensional system in different limits of the electron–electron interactions, magnetic field, and temperature. We demonstrate that the usual Hubbard-U interaction leads to strong electron localization, which enhances the local antiferromagnetic order in the system.

In the present study, the impurity binding energy (IBE) and the normalized IBE (NIBE) of GaAs quantum dot (QD) are meticulously scrutinized. The QD contains Gaussian impurity as dopant. Gaussian white noise, applied via two different routes (additive and multiplicative), also becomes part of the QD confinement potential. The IBE and NIBE exhibit (depending on presence/absence of noise, mode of entrance of noise and the given physical parameter undergoing change) steady growth, steady fall, and maximization. Over the whole study, the NIBE plots efficiently manifest some intricate features which IBE plots fail to do and establish their greater efficacy over the IBE plots in unveiling the influences of various physical parameters. The findings of the study appear to be quite pertinent in realizing the optical properties of low‐dimensional nanostructures containing impurity and under the aegis of noise.
