Item Бозе-эйнштейновский конденсат экситонов и связанные фонон-ротонны х моды [Articol](CEP USM, 2022-11-10) Клюканов, Александр; Ника, Денис; Варзарь, Александру; Baтаву, CepджиуItem Люминесценция в CdTe и многоквантовые фонон- плазмонные переходы связанных электронов [Articol](Editura USM, 2024) Варзарь, АлександруIn this article, the problem of radiative band-impurity transitions in CdTe with a large number of phonon – plasmon replicas was resolved within the framework of the Green’s function method and the Fluctuation-Dissipation Theorem taking into account the interaction with phonon-plasmon coupling. During the analysis of the correlation function (causal Green’s function) in the Random Phase Approximation and Debye-Waller Approximation using second quantization the form-function of the impurity luminescence spectrum with a multiquantum equidistant structure was obtained.Item Численный анализ энергетического спектра экситона в CdTe [Articol](CEP USM, 2021) Варзарь, АлександруIn this article, the energy spectrum of an exciton in CdTe is calculated using a numerical minimization method. For this, the Schrödinger equation is solved in the impulse representation with the potential deduced in [1]. The relevance of the problem is that this potential is solved numerically for the first time. The importance of the problem is that this potential makes it possible to find the energy spectrum of the exciton for different materials (in this case, it is CdTe).Item Экситонный переход мотта в кристалла X CdTe [Articol](CEP USM, 2022-11-10) Клюканов, Александр; Ника, Денис; Варзарь, Александру; Baтаву, Серджиу
