Abstract

The exact solution to the master equation of a nonlinear oscillator, subject to damping or amplification, is presented. The effect of such incoherent processes on the quantum-coherence properties and recurrences is obtained. It is shown that amplification destroys quantum coherence more rapidly than does attenuation.

Solution of the Master Equation for an Attenuated or Amplified Nonlinear Oscillator with an Arbitrary Initial Condition

S. Chaturvedi, Venkatraman Srinivasan

Using the thermo-field dynamics notation, an elegant solution of the master equation for an attenuated or amplified nonlinear oscillator is presented. It is found that, in this notation, the solution of the master equation under consideration amounts to a simple modification of that for the linear oscillator.

Markovian master equation for nonlinear systems

O de los Santos-Sánchez, J. Récamier, Rocío Jáuregui

Within the f -deformed oscillator formalism, we derive a Markovian master equation for the description of the damped dynamics of nonlinear systems that interact with their environment. The applicability of this treatment to the particular case of a Morse-like oscillator interacting with a thermal field is illustrated, and the decay of quantum coherence in such a system is analyzed in terms of the evolution on phase space of its nonlinear coherent states via the Wigner function.

Crossover from coherent to incoherent dynamics in damped quantum systems

Reinhold Egger, Hermann Grabert, Ulrich Weiß

The destruction of quantum coherence by environmental influences is investigated by taking the damped harmonic oscillator and the dissipative two-state system as prototypical examples. It is shown that the location of the coherent-incoherent transition depends to a large degree on the dynamical quantity under consideration.

SOLVING THE MASTER EQUATION FOR AN ATTENUATED OR AMPLIFIED NONLINEAR OSCILLATOR VIA A SUPEROPERATOR METHOD

Huai-Xin Lu, Zeng‐Bing Chen, YONG-DE ZHANG

Using the decomposition theorm of superoperators, an explicit solution of the master equation for an attenuated or amplified nonlinear oscillator is presented. It is found that the time evolution of the density operator can be easily obtained from an arbitary initial state using this method.

Nonlinear thermodynamic quantum master equation: Properties and examples

Hans Christian Öttinger

The quantum master equation obtained from two different thermodynamic arguments is seriously nonlinear. We argue that, for quantum systems, nonlinearity occurs naturally in the step from reversible to irreversible equations and we analyze the nature and consequences of the nonlinear contribution. The thermodynamic nonlinearity naturally leads to canonical equilibrium solutions and extends the range of validity to lower temperatures. We discuss the Markovian character of the thermodynamic quantum master equation and introduce a solution strategy based on coupled evolution equations for the eigenstates and eigenvalues of the density matrix. The general ideas are illustrated for the two-level system and for the damped harmonic oscillator. Several conceptual implications of the nonlinearity of the thermodynamic quantum master equation are pointed out, including the absence of a Heisenberg picture and the resulting difficulties with defining multitime correlations.

Dissipative Quantum and Classical Liouville Mechanics of the Anharmonic Oscillator

Gerard J Milburn, Catherine A. Holmes

We present a solution for the dynamics of an anharmonic oscillator coupled to a zero-temperature heat bath. Comparison of observable properties in a classical and quantum description uses true joint phase-space probability densities. The time evolution of the density in the quantum case is rapidly "reduced" to that given in the classical description. The rate of reduction is proportional to the product of the damping rate and the oscillator's initial energy. Quite rapidly, typical quantum recurrence effects are destroyed and the classical "whorl" structure restored. We point out the close similarity with rapid destruction of quantum coherence through dissipation.
