Artificial Gauge Fields with Ultracold Atoms in Optical by Monika Aidelsburger

By Monika Aidelsburger

This paintings reviews at the new release of synthetic magnetic fields with ultracold atoms in optical lattices utilizing laser-assisted tunneling, in addition to at the first Chern-number size in a non-electronic system.

It begins with an advent to the Hofstadter version, which describes the dynamics of charged debris on a sq. lattice subjected to powerful magnetic fields. This version shows strength bands with non-zero topological invariants known as Chern numbers, a estate that's on the foundation of the quantum corridor influence. the most a part of the paintings discusses the belief of analog platforms with ultracold impartial atoms utilizing laser-assisted-tunneling ideas either from a theoretical and experimental perspective. Staggered, homogeneous and spin-dependent flux distributions are generated and characterised utilizing two-dimensional optical super-lattice potentials. also their topological houses are studied through the remark of bulk topological currents.

The experimental ideas awarded the following provide a distinct surroundings for learning topologically non-trivial platforms with ultracold atoms.
