On the numerical evaluation of real-time path integrals: Double exponential integration and the Maslov correction
R. Rosenfelder
Ooura's double exponential integration formula for Fourier transforms is applied to the oscillatory integrals occuring in the path-integral description of real-time Quantum Mechani…
Scattering Theory with Path Integrals
R. Rosenfelder
Starting from well-known expressions for the -matrix and its derivative in standard nonrelativistic potential scattering I rederive recent path-integral formulations due to Efim…
Path Integrals in Quantum Physics
R. Rosenfelder
These lectures are intended for graduate students who want to acquire a working knowledge of path integral methods in a wide variety of fields in physics. In general the presentati…
A New Path-Integral Representation of the -Matrix in Potential Scattering
J. Carron, R. Rosenfelder
We employ the method used by Barbashov and collaborators in Quantum Field Theory to derive a path-integral representation of the -matrix in nonrelativistic potential scattering…
Exact Path-Integral Representations for the -Matrix in Nonrelativistic Potential Scattering
R. Rosenfelder
Several path integral representations for the -matrix in nonrelativistic potential scattering are given which produce the complete Born series when expanded to all orders and th…
Variational Approximations in a Path-Integral Description of Potential Scattering
J. Carron, R. Rosenfelder
Using a recent path integral representation for the T-matrix in nonrelativistic potential scattering we investigate new variational approximations in this framework. By means of th…
