Heisenberg equation and constants of the motion for an anharmonic oscillator in the high-frequency limit

L DeFalco, R. Mignani, Roberto Scipioni

Published Jan 1, 1997• 1 citation

Abstract

Using the best approximation of the time evolution operator of a quartic oscillator in the high-frequency limit, we derive its equation of the motion in the Heisenberg picture and show that such an anharmonic oscillator admits a wider class of constants of the motion than the standard harmonic oscillator.

Quantum-Classical Correspondence in a Quartic Oscillator -- Corrections to Frequency and Bounds for Periodic Motion

Biswas, Mandas, Deb Shankar Ray

We take a qualitative comparative look at quantum and classical quartic anharmonic oscillators. It has been shown that the behavior of the quantum anharmonic oscillator mimics that of the classical anharmonic oscillators with the structurally same Hamiltonian in the coherent state basis of the harmonic oscillators. The associated equation of motion allows us to use Lindstet-Poincare perturbation method to compute the classical frequency of the oscillation order by order, by taking care of its dependence on amplitude and the quantum corrections. We also derive a bound for periodicity of such oscillations in both the classical and quantum cases.

Theory of a quantum anharmonic oscillator

Salvatore Carusotto

The time evolution of a quantum single-quartic anharmonic oscillator is considered. The study is carried on in operational form by use of the raising and lowering operators of the oscillator. The equation of motion is solved by application of a new integration method based on iteration techniques, and the rigorous solutions that describe the time development of the displacement and momentum operators of the oscillator are obtained. These operators are presented as a Laplace transform and a subsequent inverse Laplace transform of suitable functionals. Finally, the results are employed to describe the time evolution of a quasiclassical anharmonic oscillator.

Comment on: The Magnus expansion for the harmonically driven harmonic oscillator

Francisco Marcelo Fernández

The exponential time-evolution operator for the harmonically driven harmonic oscillator is exactly obtained from the equations of motion for the coordinate and momentum in the Heisenberg representation. The convergence of the Magnus expansion is discussed.

Exponential time-evolution operator for the time-dependent harmonic oscillator

Francisco Marcelo Fernández

The time-evolution operator for the time-dependent harmonic oscillator H= (1)/(2) {α(t)p2 +β(t)q2} is exactly obtained as the exponential of an anti-Hermitian operator. The method is based on the equations of motion for the coordinate and momentum operators in the Heisenberg representation. The problem is reduced to solving the classical equations of motion.

Relation between the solutions of Newton's and Heisenberg's equations of motion

Francis R. Halpern

For a class of problems it is shown that a solution to Newton's equation of motion may be interpreted as the generating function for the matrix elements of the coordinate operators in the Heisenberg representation. For three one-dimensional problems, the harmonic oscillator, the particle in a box, and the ${x}^{4}$ anharmonic oscillator, solutions to the quantum-mechanical problem are given in terms of the classical solution. A brief examination is made of a two-dimensional problem in which the angular momentum is conserved.

Exact solution to a quantum-forced anharmonic oscillator

Jialun Zhang, Raphaël Khan, Sheng Ding +1 more

The exact solution to a quantum forced anharmonic oscillator is derived. The equation of motion is solved by using the integral operators and iteration method. As a result, the time development of the displacement and momentum operators of the forced anharmonic oscillator is obtained. These operators are presented as a Laplace and a subsequent inverse Laplace transform of suitable functionals.
