Optimally driving multi-photon transitions in the perturbative single-mode regime

Frieder Lindel, Stefan Yoshi Buhmann, Andreas Buchleitner +1

The rate of -photon transitions in matter, induced by an incident light field, depends on the field's th order coherence function. Consequently, the coherence properties of t…

Time-periodic driving of a bath-coupled open quantum gas of light

Andris Erglis, Alexander Sazhin, Frank Vewinger +3

We study the frequency-resolved density response of a photon Bose-Einstein condensate coupled to a bath of dye molecules by time-periodic driving. By monitoring the photon number d…

Photoelectron circular dichroism of a chiral molecule induced by resonant interatomic Coulombic decay from an antenna atom

Stefan Yoshi Buhmann, Andreas Hans, Janine C. Franz +1

We show that a nonchiral atom can act as an antenna to induce a photoelectron circular dichroism in a nearby chiral molecule in a three-step process: The donor atom (antenna) is in…

Experimentally separating vacuum fluctuations from source radiation

Alexa Herter, Frieder Lindel, Laura Gabriel +2

The unique distinction between vacuum-field and source-radiation induced effects in processes such as the Lamb shift, Casimir forces or spontaneous emission, remains unresolved eve…

Strong coupling of a chiral molecule with circularly polarised modes inside a cavity

Lara Marie Tomasch, Fabian Spallek, Guido W. Fuchs +2

We consider the discriminatory interaction of a chiral molecule with circularly polarised modes inside a cavity. Starting from a generalised Jaynes--Cummings model that includes bo…
