Phonon dressing
WebThrough phonon-dressing, a breakdown of Fermi’s golden rule can occur for certain photonic structures whose photon decay time becomes comparable to the longitudinal acoustic phonon decay times. We present a polaron master equation model to calculate the photoluminescence intensity from a coherently excited quantum dot coupled to a … WebTo further explore the competition between the phonon and dressing effects, we investigated intensity-noise correlation of spontaneous parametric four-wave mixing at 110 K. Our results demonstrate the dependency of YSO crystal on temperature, detuning, and power, which can be controlled by the competition between a phonon with single and …

Web— Gregory Mone, Discover Magazine, 16 July 2012 When a group of atomic nuclei vibrate, their collective excitation is instead called a phonon. — Daniel Garisto, Scientific American … WebEnergy shift, broadening, and complex intensity variation and oscillation at twice the phonon frequency for the valence bands are observed at time scales ranging from the femtosecond to the picosecond and beyond. The underlying physics is rich, including ponderomotive interaction, dressing of the electronic states, creation of coherent phonon ...
WebWe also found that the phonon dressing of the SG kink by the ac driver, χ(t) , was necessary for the occurrence of a directed energy current in the SG equation. We show in the case of the double sine-Gordon (DSG) equation that the excitation of the internal mode, R(t) (where R(t) is the separation of the two subkinks that make up the DSG ...
