Dimensional crossover in trapped photon gases (B06)

• Subject Area: Optics, Quantum Optics and Physics of Atoms, Molecules and Plasmas
• Term: since 2020
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 277625399

With a new experimental approach, the properties of trapped photon gases are investigated within the crossover between one and two spatial dimensions. Here it is of special interest to achieve the first one-dimensional photon gas by using a strongly asymmetric box-like potential. The technological base for the envisioned investigations is the possibility to imprint tailored potential landscapes by a particular coating of the cavity mirrors with photonic structures. The experimental implementation of the new setup will be accompanied by a theoretical modelling, with a special emphasize on the superfluid properties of the driven-dissipative photon gas.
