Sharp Transition for Single Polarons in the One-Dimensional Su-Schrieffer-Heeger Model
Model of polaron ground-state energy smooth transition coupling electron phonon coupling phonon coupling dynamics
2014/12/18
We study a single polaron in the Su-Schrieffer-Heeger (SSH) model using four different techniques (three numerical and one analytical). Polarons show a smooth crossover from weak to strong coupling, a...
The Kondo crossover in shot noise of a single quantum dot with orbital degeneracy
Kondo crossover orbital degeneracy
2010/11/19
We investigate out of equilibrium transport through an orbital Kondo system realized in a single quantum dot, described by the multiorbital impurity Anderson model. Shot noise and current are calculat...
Quantum Fluctuations Contribution to the Random Walk of a Single Molecule and New Estimate of the Planck Constant
Quantum Fluctuations Random Walk Planck Constant
2010/3/10
It is shown, by considering the case of the harmonic oscillator, that quantum fluctuations may be the most significant contribution to the random walk of a single molecule. From this point, the contro...
At the Institute in Physical–Technical Problems experiments on sonoluminescence was
started by our group at the beginning of this year. Our study was focused at properties of
the single bubble mode ...
