WebJun 20, 2024 · For atoms in the ground band of the lattice, the evolution in the combined potential takes the form of Bloch oscillations [ 32 – 36 ]. Relativistic dynamics are initiated after a variable hold time by amplitude modulation of the lattice beam intensity which resonantly excites a fraction of the atoms to the third band. 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.
