Explicit evaluation of a path integral with memory kernel

F. Brosens, J. T. Devreese

Published Jun 1, 1984• 11 citations

Abstract

An explicit expression is presented for the path integral of an harmonic oscillator interacting with itself in the past. The time dependence of the memory kernel is assumed to be exponential. The relation with the Feynman trial action for the variational calculation of the polaron ground state energy is discussed.

Path integration of the time-dependent forced oscillator with a two-time quadratic action

Tian Rong Zhang, Bin Kang Cheng

Using the prodistribution theory proposed by DeWitt-Morette [C. DeWitt-Morette, Commun. Math. Phys. 28, 47 (1972); C. DeWitt-Morette, A. Maheshwari, and B. Nelson, Phys. Rep. 50, 257 (1979)], the path integration of a time-dependent forced harmonic oscillator with a two-time quadratic action has been given in terms of the solutions of some integrodifferential equations. We then evaluate explicitly both the classical path and the propagator for the specific kernel introduced by Feynman in the polaron problem. Our results include the previous known results as special cases.

Path integration of a general two-time quadratic action by prodistribution approach

Dinkar C. Khandekar, Sunil Datta, S. V. Lawande

The theory of prodistributions is applied to path integrate a general two-time quadratic action characterizing memory effects. The resulting Feynman propagator is exact and is in the form of an exponential integral over a single variable. A case where the integral is explicitly evaluated, for an arbitrary memory kernel, is presented to highlight the closed analytical structure of the propagator obtained. All special cases treated in the literature follow from this general expression.

Harmonic Oscillator, Coherent States, and Feynman Path Integral yz

Dae-Yup Song

The Feynman path integral for the generalized harmonic oscillator is reviewed, and it is shown that the path integral can be used to nd a complete set of wave functions for the oscillator. Harmonic oscillators with dierent (time-dependent) parameters can be related through unitary transformations. The existence of generalized coherent states for a simple harmonic oscillator can then be interpreted as the result of a (formal) invariance under a unitary transformation which relates the same harmonic oscillator. In the path integral formalism, the invariance is reflected in that the kernels do not depend on the choice of classical solutions.

Harmonic Oscillator, Coherent States, and Feynman Path Integral

Dae-Yup Song

The Feynman path integral for the generalized harmonic oscillator is reviewed, and it is shown that the path integral can be used to find a complete set of wave functions for the oscillator. Harmonic oscillators with different (time-dependent) parameters can be related through unitary transformations. The existence of generalized coherent states for a simple harmonic oscillator can then be interpreted as the result of a (formal) {\em invariance} under a unitary transformation which relates the same harmonic oscillator. In the path integral formalism, the invariance is reflected in that the kernels do not depend on the choice of classical solutions.

Path Integral Evaluation of a Time-Dependent Oscillator in an External Field

A. N. Ikot, Eno E. Ituen, Ime. E. Essien +1 more

The Lagrangian of a system describing the dynamical behaviour of a time-dependent harmonic oscillator is modified and then used to evaluate the Feynman path integral of the oscillator. The path integral of the time-dependent oscillator is shown to reduce to the time-independent within certain limits.

Gaussian path integrals

Belal Ehsan Baaquie

Several path integrals are exactly evaluated here using Gaussian path integration. A few general ideas are illustrated using the advantage of being able to exactly evaluate Gaussian path integrals. Path integrals defined over a particular collection of allowed indeterminate paths can sometimes be represented by a Fourier expansion of the paths. This leads to two important techniques for performing path integrations: Expanding the action about the classical solution of the Lagrangian; Expanding the degree of freedom in a Fourier expansion of the allowed paths. Various cases are considered to illustrate the usage of classical solutions and Fourier expansions, and these also provide a set of relatively simple examples to familiarize oneself with the nuts and bolts of the path integral. The Lagrangian of the simple harmonic oscillator is used for all of the following examples; all the computations are carried out explicitly and exactly. The following different cases are considered: • Correlators of exponential functions of the degree of freedom are discussed in Section 12.1. • The generating functional for periodic paths is evaluated in Section 12.2. • The path integral required for evaluating the normalization constant for the oscillator evolution kernel is discussed in Section 12.3. The path integral entails summing over all paths that start from and return to the same fixed position. • Section 12.4 discusses the evolution kernel for a particle starting at an initial position x i and, after time τ, having a final position that is indeterminate.
