This review focuses on the studies and computations of few-body systems of electrons and
holes in condensed matter physics. We analyze and illustrate the application of a variety of …

We develop the theoretical formalism and study the formation of valley trions in two-
dimensional monolayers within the framework of a nonrelativistic potential model using the …

In this study, a detailed investigation of the nonlinear optical properties such as optical
absorption and refractive index change associated with intersubband transitions in a three …

We develop the theoretical formalism and study the formation of valley trions in transition
metal dichalcogenide (TMDC) monolayers within the framework of a non-relativistic potential …

We consider the Hamiltonian of a three-electron quantum dot composed of quadratic plus
Coulomb terms and calculate the system's spectra. We next apply the hyperradius to reduce …

The Schrödinger equation is solved for a particle confined within the ellipsoidal potential
well using the perturbation theory and the Hamiltonian diagonalization method. The explicit …

Three electrons confined by a parabolic well in a two-dimensional quantum dot and
interacting via a logarithmic potential in a magnetic field are treated in the framework of the …

We consider a restricted three-body problem, where two interacted particles are located in a
two-dimensional (2D) plane and interact with the third one located in the parallel spatially …

A system of three identical charged particles in a two-dimensional harmonic well produced
by an external potential and a transverse magnetic field is treated in the framework of the …

We consider the Hamiltonian of a three-electron-quantum dot composed of parabolic
confinement plus Coulomb terms. Instead of using the Jacobi coordinates, we apply a …
