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 WebThe concept of Bloch oscillations is of prime significance for transport in all crys-tal structures.
