Gauge fields and topological states with cold atoms (C05)

• Subject Area: Optics, Quantum Optics and Physics of Atoms, Molecules and Plasmas
• Term: since 2016
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 277625399

Quantum Hall physics is at the heart of research on matter with non-trivial topological order. Atoms are electrically neutral, but in such systems synthetic magnetic fields can be created by phase imprinting from Raman manipulation. This project studies strong synthetic magnetic fields for a quantum gas of bosonic erbium atoms. The used rare earth atomic system allows for state-dependent Raman manipulation with long coherence times, and the imprinting of strong synthetic magnetic fields. We will observe fractional quantum Hall physics in a well controlled cold atomic gas system.
