Taschenbuch. Condizione: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - El objetivo de esta monografía es presentar un nuevo método para resolver los problemas perturbados independientes del tiempo en la mecánica cuántica no relativista. En este método se desarrolla el operador de evolución de la ecuación de Schrödinger dependiente del tiempo en serie de Taylor, y se identifican los términos de dicha serie con los elementos de ciertas matrices triangulares. A partir de esta observación, se construye un conjunto fácilmente soluble de ecuaciones diferenciales para las matrices triangulares, y se encuentra de manera simultánea la corrección a la energía y la corrección a la función de onda. Dado que el método que resulta utiliza matrices, se le bautizó como 'Método matricial'. Presentamos también algunos ejemplos y aplicaciones a la óptica cuántica y a la ecuación maestra. El método matricial tiene las siguientes ventajas: i) el desarrollo es sistemático, la corrección de cualquier orden es obtenida en forma directa y general, ii) al tomar en cuenta todos los términos se obtiene la serie de Dyson, iii) las correcciones a la energía y a la función de onda son obtenidas en una sola operación de manera simultánea, y iv) pedagógicamente es más conveniente.…

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book provides an alternative approach to time-independent perturbation theory in non-relativistic quantum mechanics. It allows easy application to any initial condition because it is based on an approximation to the evolution operator and may also be used on unitary evolution operators for the unperturbed Hamiltonian in the case where the eigenvalues cannot be found. This flexibility sets it apart from conventional perturbation theory. The matrix perturbation method also gives new theoretical insights; for example, it provides corrections to the energy and wave function in one operation. Another notable highlight is the facility to readily derive a general expression for the normalization constant at m-th order, a significant difference between the approach within and those already in the literature. Another unique aspect of the matrix perturbation method is that it can be extended directly to the Lindblad master equation. The first and second-order corrections are obtained for this equation and the method is generalized for higher orders. An alternative form of the Dyson series, in matrix form instead of integral form, is also obtained. Throughout the book, several benchmark examples and practical applications underscore the potential, accuracy and good performance of this novel approach. Moreover, the method's applicability extends to some specific time-dependent Hamiltonians. This book represents a valuable addition to the literature on perturbation theory in quantum mechanics and is accessible to students and researchers alike. 190 pp. Englisch.…
