Accurate determination of spectra in discrete-time quantum mechanics

Carl M. Bender, Matthew L. Green

Published Nov 15, 1986• 10 citations
Publisher

Abstract

Various approximation schemes have been proposed which discretize the operator Heisenberg equations of motion. In this paper we demonstrate a simple and accurate method for obtaining the energy spectrum of the theory directly from the discrete-time equations of motion.

Quantum Tunneling Using Discrete-Time Operator Difference Equations

Canonical discrete-time operator difference equations are introduced as an alternative approach to the numerical solution of a quantum field theory. We apply these techniques to the solution of the operator Heisenberg equations of motion describing the problem of quantum-mechanical tunneling. Our numerical solutions accurately depict the time evolution of $〈{q}^{n}〉$ and of a local probability measure.

Unified theory of annihilation-creation operators for solvable (“discrete”) quantum mechanics

Satoru Odake, Ryu Sasaki B

The annihilation-creation operators a(±) are defined as the positive/negative frequency parts of the exact Heisenberg operator solution for the “sinusoidal coordinate”. Thus a(±) are hermitian conjugate to each other and the relative weights of various terms in them are solely determined by the energy spectrum. This unified method applies to most of the solvable quantum mechanics of single degree of freedom including those belonging to the “discrete” quantum mechanics.

Canonical discrete-time operator difference equations are introduced as an alternative approach to the numerical solution of a quantum field theory. We apply these techniques to the solution of the operator Heisenberg equations of motion describing the problem of quantum-mechanical tunneling. Our numerical solutions accurately depict the time evolution of 〈qn〉〈{q}^{n}〉〈qn〉 and of a local probability measure.
