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.

Webthe system Bloch oscillates. Owing to the Zener tunneling the system tends to go the upper energy band and stay there. A single electron tunneling through the junction #1 to the base recovers the system to the lower energy band and the system starts to Bloch oscillate again.

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 ...
