Crossover from coherent to incoherent dynamics in damped quantum systems

Reinhold Egger, Hermann Grabert, Ulrich Weiß

Published Apr 1, 1997• 51 citations
arXivHTMLPDF

Abstract

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.

Oscillatory Dynamics and Non-Markovian Memory in Dissipative Quantum Systems

Dante Marvin Kennes, Oleksiy Kashuba, Mikhail Pletyukhov +2 more

The nonequilibrium dynamics of a small quantum system coupled to a dissipative environment is studied. We show that (i) the oscillatory dynamics close to a coherent-to-incoherent transition is significantly different from the one of the classical damped harmonic oscillator and that (ii) non-Markovian memory plays a prominent role in the time evolution after a quantum quench.

Dynamical regimes of dissipative quantum systems

Dante Marvin Kennes, Oleksiy Kashuba, V. Meden

We reveal several distinct regimes of the relaxation dynamics of a small quantum system coupled to an environment within the plane of the dissipation strength and the reservoir temperature. This is achieved by discriminating between coherent dynamics with damped oscillatory behavior on all time scales, partially coherent behavior being nonmonotonic at intermediate times but monotonic at large ones, and purely monotonic incoherent decay. Surprisingly, elevated temperature can render the system ``more coherent'' by inducing a transition from the partially coherent to the coherent regime. This provides a refined view on the relaxation dynamics of open quantum systems.

Quantum dynamics of damped and driven anharmonic oscillators

Michael J. Schrapp, Elena del Valle, Jonathan James Finley +1 more

Abstract We study various techniques to characterize the quantum states of a strongly dissipative system, namely, the an‐harmonic oscillator. One cannot directly access the quantum states themselves but only transitions between them. Various methods bring various advantages and inconvenients. We compare several observables under coherent and incoherent excitation. Incoherent excitation leads to huge broadening while coherent excitation quickly dresses the system at the energies required to access the excited states. Less perturbative methods such as four wave mixing appear to be superior but are, by construction, only usable for the lowest rungs. (© 2012 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

Crossover from coherent to incoherent quantum dynamics due to sub-Ohmic dephasing

P. Nalbach, Michael Thorwart

We report exact results for the influence of purely sub-Ohmic dephasing on the dynamics of a quantum two-level system. From response functions, we determine a crossover coupling strength between oscillatory coherent and overdamped dynamics. Surprisingly, we find no overdamping even at arbitrary large dephasing for spectra with spectral exponent $s<{s}_{c}$. For ${s}_{c}<s\ensuremath{\le}1$ we observe a crossover to overdamped dynamics but a reemergence of oscillatory behavior at very large couplings. Thus experimentally tuning the character of fluctuations from relaxational to dephasing should allow us to suppress the dephasing character of sub-Ohmic and thus $1/f$ noise.

Nonlinear response of a periodically driven damped two-state system

Milena Grifoni, Maura Sassetti, Jürgen T. Stockburger +1 more

We study the nonlinear response of a periodically driven dissipative two-state system. The exact formal solution in the form of a series in the number of system transitions is derived. The series is summed in analytic form in the parameter region where incoherent transitions prevail. We also present the exact solution for the time evolution of the system in the entire region of temperatures and driving strength for a special value of the Ohmic viscosity. The destruction of quantum coherence by incoherent processes which are induced by the fluctuating and the driving forces is discussed on the basis of these solutions.

Destruction of quantum coherence in a nonlinear oscillator via attenuation and amplification

D. J. Daniel, Gerard J Milburn

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.
