Bloch oscillate
WebnanoHUB WebWe find that a dark-state polariton, which is formed by an atomic ensemble dressed by the photon can display a typical quantum interference effect (i.e., the quasiparticle Bloch oscillation). The dark-state polariton is subjected to a washboard configuration potential with a spatially uniform force and a periodic potential provided by the ...
Bloch oscillate
Did you know?
Bloch oscillation is a phenomenon from solid state physics. It describes the oscillation of a particle (e.g. an electron) confined in a periodic potential when a constant force is acting on it. It was first pointed out by Felix Bloch and Clarence Zener while studying the electrical properties of crystals. In … See more Bloch oscillations were predicted by Nobel laureate Felix Bloch in 1929. However, they were not experimentally observed for a long time, because in natural solid-state bodies, $${\displaystyle \omega _{B}}$$ is (even with very … See more • Super Bloch oscillations See more Web% This code is meant to simulate bloch oscillations in a slowly modulated band % structure: close all; clear all; doSave = 1; filename = ' BO.gif '; %% experiment parameters % Specify fundamental constants and other fixed parameters: amu = 1.66E-27; % atomic mass unit in kg: mLi = 7 * amu; % mass of lithium in kg

WebBloch oscillations in a tilted ladder lattice are studied in the presence of artificial magnetic flux. The oscillations exhibit chiral characteristics which may be used to distinguish the Meissner phase and the vortex phase. By incorporating the diagonal hopping into the ladder, the dynamical evolution reveals a phase transition as the diagonal ...
WebOptical lattices have developed into successful model systems for effects known or predicted in solid state physics 5 .Bloch oscillations, in which an atom subject to a force performs an oscillatory rather than a uniformly accelerated motion, are one of the most striking quantum transport property arising from the periodic potential 6 .In other works, … reagents是什么意思WebBloch oscillations, arising when electrons are driven through a perfect crystal lattice by an electric eld, are an iconic example of a coherent dynamics in quantum many-body systems[1, 2].
