Quantum synchronization
Using the methods of quantum trajectories we study numerically the phenomenon of quantum synchronization in a quantum dissipative system with periodic driving. Our results show that at small values of Planck constant ~ the classical devil’s staircase remains robust with respect to quantum fluctuations while at large ~ values synchronization plateaus are destroyed. Quantum synchronization in our...
متن کاملPhase Synchronization
Assume that the processes communicate through shared variables; contentions for access (read or write) to a shared variable by different processes are resolved arbitrarily but fairly (i.e., any process attempting to read/write a shared variable will do so eventually). Nothing may be assumed about the initial values of the shared variables. In the absence of this requirement, the following simpl...
متن کاملQuantum stochastic synchronization.
We study, within the spin-boson dynamics, the synchronization of a quantum tunneling system with an external, time-periodic driving signal. As a main result, we find that at a sufficiently large system-bath coupling strength (i.e., for a friction strength alpha > 1) the thermal noise plays a constructive role in yielding forced synchronization. This noise-induced synchronization can occur when ...
متن کاملIrrational phase synchronization.
We study the occurrence of physically observable phase locked states between chaotic oscillators and rotors in which the frequencies of the coupled systems are irrationally related. For two chaotic oscillators, the phenomenon occurs as a result of a coupling term which breaks the 2 pi invariance in the phase equations. In the case of rotors, a coupling term in the angular velocities results in ...
متن کاملTesting for phase synchronization
Phase synchronization analysis is frequently applied to data originating for example from Physics and Life Sciences. Statistical properties for quantities measuring phase synchronization have not been revealed. We derive an analytic significance level for a frequently used phase synchronization measure. Its performance is demonstrated for a system of coupled oscillators. 2007 Elsevier B.V. Al...
