A magnon is a quasiparticle, a collective excitation of the spin structure of an electron in a crystal lattice. In the equivalent wave picture of quantum mechanics, a magnon can be viewed as a quantized spin wave. Magnons carry a fixed amount of energy and lattice momentum, and are spin-1, indicating they obey boson behavior. WebJul 31, 2024 · The traditional view of Bloch oscillations is that they rely on the translational symmetry of crystals. These oscillations occur with a fundamental period ${T}_{B}$, the time it takes a semiclassical wave packet to travel across the Brillouin zone. We introduce a new type of Bloch oscillation whose period equals an integer multiple of ${T}_{B}$.
