Real-space imaging of a topological protected edge state with ultracold atoms in an amplitude-chirped optical lattice
Martin Leder, Christopher Grossert, Lukas Sitta +3
Topological states of matter, as quantum Hall systems or topological insulators, cannot be distinguished from ordinary matter by local measurements in the bulk of the material. Ins…

The Floquet-Boltzmann equation
Maximilian Genske, Achim Rosch
Periodically driven quantum systems can be used to realize quantum pumps, ratchets, artificial gauge fields and novel topological states of matter. Starting from the Keldysh approa…
