УРАВНЕНИЕ ПАУЛИ ДЛЯ ЧАСТИЦЫ СО СПИНОМ 1 В СФЕРИЧЕСКОМ ПРОСТРАНСТВЕ РИМАНА, ТОЧНЫЕ РЕШЕНИЯ

Abstract

The system of nonrelativistic Pauli equations for a spin 1 particle is solved in the case of the Riemann space of constant positive curvature. The system of three interrelated radial equations is divided into two subsystems with the use of a space reflection operator: one and two equations, respectively. The first is solved in hypergeometric functions straightforwardly. The second subsystem gives two 4-order ordinary differential equations; they are solved with the use of the factorization method: energy spectra and wave functions are found.

Spin 1/2 particle with anomalous magnetic moment and polarizability in the external magnetic field

Ивашкевич, А.В., Саченок, П.О., Овсиюк, Е.М. +5 more

Уравнение для частицы со спином 1/2 и двумя дополнительными характеристиками – аномальным магнитным моментом и поляризуемостью – исследовано при наличии внешнего однородного магнитного поля. После разделения переменных получена система четырех дифференциальных уравнений в полярной координате. Для решения системы применяется метод Федорова – Гронского, основанный на использовании проективных операторов. Согласно этому подходу, четыре полярные компоненты выражаются через две различные функции, последние сводятся к вырожденному гипергеометрическому уравнению; при этом возникает правило квантования. Построены два типа волновых функций, соответствующие энергетические спектры найдены в аналитическом виде и исследованы численно. = In the present paper, we examine the equation for a spin 1/2 particle with two additional characteristics, anomalous magnetic moment and polarizability in presence of external uniform magnetic field. After separating the variables, we derive the system of four differential equations in the polar coordinate. To resolve the system of equations, we apply the method by Fedorov – Gronskiy, which is based on the use of projective operators. According to this approach, four polar components are expressed through only two different functions, the last reduce to the confluent hypergeometric equation; moreover there arises a definite quantization rule. We have constructed two types of the wave functions, the corresponding energy spectra are found in analytical form. The energy spectra are studied numerically as well.

КВАНТОВАЯ МЕХАНИКА ЧАСТИЦЫ СО СПИНОМ 1 И АНОМАЛЬНЫМ МАГНИТНЫМ МОМЕНТОМ В МАГНИТНОМ ПОЛЕ

The generalized Duffin–Kemmer equation for a spin 1 particle with the anomalous magnetic moment in the external uniform magnetic field is investigated. The separation of variables in the wave equation is performed on the basis of projective operator techniques. The problem is reduced to a system of differential equations for three independent functions that have been solved in terms of the confluent hypergeometric functions. Three series of the energy levels are found. To assign them the physical sense at all values of the main quantum number n = 0,1, 2, , special restrictions on anomalous magnetic moment values must be imposed – they are formulated in explicit form. Otherwise, only some part of the energy levels corresponds to the bound states. The neutral spin 1 particle is considered as well. In this case, no bound states exist in the systems. The main qualitative manifestation of the anomalous magnetic moment is the space scaling of the arguments of the wave functions in comparison with a particle without such a moment.

The Dirac equation for spin 1/2 particle with anomalous magnetic moment is solved in presence of the external uniform magnetic field. After separation of the variables, the problem is reduced to a 4-order ordinary differential equation, which is solved exactly with the use of the factorization method. A generalized formulas for Landau energy levels are found. Solutions are expressed in terms of confluent hypergeometric functions.

Analytical study and exact solutions of the spin equation

Mario Cesar Baldiotti

O presente trabalho se destina a um estudo detalhado da chamada equação de spin, a qual pode ser utilizada para descrever o comportamento de sistemas de dois níveis. Para campos externos dados por funções reais, esta equação pode ser identificada com uma redução da equação de Pauli para o caso 0+1 dimensional. Inicialmente, demonstraremos a relação entre esta equação de spin e várias outras equações relacionadas com diversos problemas em física. Com estas relações, podemos construir novas soluções da equação de spin a partir do conhecimento de soluções exatas destes outros problemas e, por outro lado, estender a aplicação das soluções obtidas. Em seguida, descrevemos a forma geral da solução desta equação, construímos o operador de evolução e resolvemos o problema inverso, i.e., a determinação do campo externo supondo o conhecimento de uma solução. Finalizando, para o importante caso de campos externos reais, desenvolvemos um método de construção de novas soluções a partir de uma solução previamente conhecida, utilizando a chamada transformação de Darboux. Em particular, demonstramos a existência de operadores de entrelaçamento de Darboux, que não violam a estrutura específica dos sistemas de dois níveis, e permitem construir novos campos externos também dados por funções reais. Como resultado destes desenvolvimentos, apresentamos uma série de novas soluções exatas para a equação de spin.
