Artificial Gauge Fields with Ultracold Atoms in Optical Lattices
Cham : Springer International Publishing : Imprint: Springer, 2016
Abstract/Sommario:
This work reports on the generation of artificial magnetic fields with ultracold atoms in optical lattices using laser-assisted tunneling, as well as on the first Chern-number measurement in a non-electronic system. It starts with an introduction to the Hofstadter model, which describes the dynamics of charged particles on a square lattice subjected to strong magnetic fields. This model exhibits energy bands with non-zero topological invariants called Chern numbers, a property that is ...; [leggi tutto]
