WebBloch oscillations are an intriguing concept of solid state physics. When an electron experiences the force of an electric field in a periodic potential, the resulting dynamics is … WebBloch oscillations are excited by linearly polar ized pump pulses. Changes of the internal electric field along the growth direction of the superlattice are detected with circularly polarized probe pulses by comparing the intensities of the two perpendicularly polarized parts of the beam.
WebBloch 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 … WebMay 23, 2024 · We encounter the surprising phenomenon of Bloch oscillation: when one adds a constant force to the one created by the periodic lattice, the particle oscillates in space, which is very different from the motion that occurs in the absence of the lattice.
