چکیده

Stochastic fluctuations of coherent and incoherent components of the resonance fluorescence intensity induced by Wiener-Levy laser phase noise are investigated. Statistical properties of the atomic dipole moment and stochastic Mollow spectra of atomic dipole fluctuations for different values of the laser linewidth and Rabi frequency are calculated. It is shown that these spectra exhibit a triplet structure which is purely classical and entirely laser-noise dependent.

Constructive effects of noise in homoclinic chaotic systems.

Many chaotic oscillators have coherent phase dynamics but strong fluctuations in the amplitudes. At variance with such a behavior, homoclinic chaos is characterized by quite regular spikes but strong fluctuation in their time intervals due to the chaotic recurrence to a saddle point. We study influences of noise on homoclinic chaos. We demonstrate both numerically and experimentally on a CO2 la...

Stochastic Phase Dynamics in Neuron Models and Spike Time Reliability

The present thesis is concerned with the stochastic phase dynamics of neuron models and spike time reliability. It is well known that noise exists in all natural systems, and some beneficial effects of noise, such as coherence resonance and noise-induced synchrony, have been observed. However, it is usually difficult to separate the effect of the nonlinear system itself from the effect of noise...

Stochastic and coherence resonance in lasers: homoclinic chaos and polarization bistability

We report Stochastic Resonance and Coherence Resonance phenomena in experiments using CO2 lasers. First, we consider a polarized laser with feedback; for suitable feedback parameters, the laser intensity undergoes homoclinic chaos consisting in the return to a saddle focus, where noise controls the permanence time around the saddle. Second, we discuss a quasi-isotropic laser where noise induces...

Noise Induced Phase Transition in a Two-dimensional Coupled Map Lattice

The phase transition with respect to the intensity of a d-correlated noise source has been studied in a coupled map lattice that simulates the excitability of field-type neural tissues [7]. The entropy of lattice states versus this control parameter undergoes a qualitative change at the phase transition point. Its behavior is linear on one side of this point and it transforms to a cubic-root fo...

The Effects of Sine-Squared Pulse Modulation Correlated Noises on Stochastic Resonance in Single-Mode Laser

Z. Naturforsch. 66a, 411 – 416 (2011); received October 11, 2010 / revised January 8, 2011 By means of the linear approximation method, the output intensity power and signal-to-noise ratio (SNR) of a single-mode laser driven by sine-squared pulse modulation correlated noise are calculated. The effects of amplitude B, period T , and width τ on the resonance curves of SNR to the pump noise intens...
