Strong Chiral Coupling of a Molecule in a Two-Mode Cavity — •Lara Marie Tomasch, Fabian Spallek, and Stefan Yoshi Buhmann — Institut für Physik, Universität Kassel, Heinrich-Plett Str. 40, 34132 Kassel

We examine the effects of chirality on the interaction of a two-level quantum system with a single mode of the quantised electromagnetic field inside a cavity. We develop a generalised Jaynes-Cummings model and study the modified coupling constants, Rabi oscillations and eigenenergies of the system.

We generalise this system by having two chiral standing modes of opposite handedness present inside the cavity and determine their coupling to the chiral molecule. These two modes are in general detuned and may exhibit distinct coupling strengths as determined by the molecular dipole moments. We further examine the emergence of chiral-induced quantum phenomena and chiral forces acting on the molecule with potential applications in chiral sensing.
