Unusual chemical bond and spectrum of beryllium dimer in ground state
A. V. Mitin, A. A. Gusev, O. Chuluunbaatar +3
This review outlines the main results which show the dual nature of the chemical bond in diatomic beryllium molecule in the ground state. It has been shown that the bery…
On generation of the Bargmann-Moshinsky basis of SU(3) group
S. Vinitsky, C. Burdik, A. Gusev +4
An efficient procedure of orthonormalisation of the Bargmann-Moshinsky (BM) basis is examined using analytical formulas of the overlap integrals of the BM basis. Calculations of co…
Symbolic-numerical Algorithm for Generating Cluster Eigenfunctions: Tunneling of Clusters Through Repulsive Barriers
Sergue Vinitsky, Alexander Gusev, Ochbadrakh Chuluunbaatar +4
A model for quantum tunnelling of a cluster comprising A identical particles, coupled by oscillator-type potential, through short-range repulsive potential barriers is introduced f…
Symbolic-numerical algorithm for generating cluster eigenfunctions: identical particles with pair oscillator interactions
Alexander Gusev, Sergue Vinitsky, Ochbadrakh Chuluunbaatar +5
The quantum model of a cluster, consisting of A identical particles, coupled by the internal pair interactions and affected by the external field of a target, is considered. A symb…
Analytical and numerical calculations of spectral and optical characteristics of spheroidal quantum dots
A. A. Gusev, L. L. Hai, S. I. Vinitsky +5
In the effective mass approximation for electronic (hole) states of a spheroidal quantum dot with and without external fields the perturbation theory schemes are constructed in the…
Adiabatic description of nonspherical quantum dot models
A. A. Gusev, O. Chuluunbaatar, S. I. Vinitsky +6
Within the effective mass approximation an adiabatic description of spheroidal and dumbbell quantum dot models in the regime of strong dimensional quantization is presented using t…
