Vibronic dephasing model for coherent-to-incoherent crossover in DNA

Crossover from incoherent to coherent phonon scattering in epitaxial oxide superlattices.

Elementary particles such as electrons or photons are frequent subjects of wave-nature-driven investigations, unlike collective excitations such as phonons. The demonstration of wave-particle crossover, in terms of macroscopic properties, is crucial to the understanding and application of the wave behaviour of matter. We present an unambiguous demonstration of the theoretically predicted crosso...

Intermittency for Coherent and Incoherent Current Ensemble Model

We investigate the origin of intermittency for multiparticle distribution in momentum space, following the idea that there is a kind of power law distribution of the space-time region of hadron emission. Using the formalism of current ensamble model to describe boson sources we discuss intermittency exponents for the coherent and incoherent ( chaotic) particle production scheme. PACS numbers:13...

Coherent detection of electron dephasing.

We show that an Aharonov-Bohm ring with asymmetric electron injection can act as a coherent detector of electron dephasing. The presence of a dephasing source in one of the two arms of a moderately-to-highly asymmetric ring changes the response of the system from total reflection to complete transmission while preserving the coherence of the electrons propagating from the ring, even for strong ...

Coherent and Incoherent Contributions to Multisoliton Complexes

We analyze multisoliton complexes and their dynamics in Kerr-like nonlinear media. The field in each of M incoherently interacting components is calculated using an integrable set of coupled nonlinear Schrödinger equations. We obtain a general N-soliton solution describing propagation of multisoliton complexes and their collisions. The evolution of such higher-order soliton beams is determined ...
