چکیده
A mathematically rigorous realization of Feynman integrals is given. The construction works for quadratic actions (there is only a restriction to certain time intervals). These techniques enable the calculation of the semi-classical approximation for a given Feynman prop-agator. Finally, delta sequences in Gaussian analysis are presented and their connection to semi-classical approximation is discussed.

Quadratic Actions, Semi-classical Approximation, and Delta Sequences in Gaussian Analysis
A mathematically rigorous realization of Feynman integrals is given. The construction works for quadratic actions (there is only a restriction to certain time intervals). These techniques enable the calculation of the semi-classical approximation for a given Feynman propagator. Finally, delta sequences in Gaussian analysis are presented and their connection to semi-classical approximation is di...
متن کاملThe Quadratic Zeeman Effect in Hydrogen: an Example of Semi-classical Quantization of a Strongly Non-separable but Almost Integrable System
Semi-classical quantization of multidimensional systems is discussed both in terms of the Einstein-Brillouin-Keller quantization on invariant tori, and in terms of infinite families of periodic orbits. The notions of separability, integrability, and non-integrability of classical systems are introduced. An approximate integrability is used to quantize the quadratic Zeeman problem, via analytic ...
متن کاملContinuous Discrete Variable Optimization of Structures Using Approximation Methods
Optimum design of structures is achieved while the design variables are continuous and discrete. To reduce the computational work involved in the optimization process, all the functions that are expensive to evaluate, are approximated. To approximate these functions, a semi quadratic function is employed. Only the diagonal terms of the Hessian matrix are used and these elements are estimated fr...
متن کاملThe two limits of the Schrödinger equation in the semi-classical approximation: discerned and non-discerned particles in classical mechanics
We study, in the semi-classical approximation, the convergence of the quantum density and the quantum action, solutions to the Madelung equations, when the Planck constant h tends to 0. We find two different solutions which depend to the initial density . In the first case where the initial quantum density is a classical density ρ0(x), the quantum density and the quantum action converge to a cl...
متن کاملQUADRATIC STARK CONSTANTS OF NEUTRAL COPPER SPECTRAL LINES IN THE COULOMB APPROXIMATION
Quadratic Stark constants of neutral copper spectral lines for all s,p, and d levels are calculated using the Coulomb approximation. These results are compared with existing data and, generally, good agreement is observed
