Born-Oppenheimer approximation in optical cavities: from success to breakdown
Csaba Fábri, Gábor J. Halász, Lorenz S. Cederbaum +1
The coupling of a molecule and a cavity induces non-adiabaticity in the molecule which makes the description of its dynamics complicated. For polyatomic molecules, reduced-dimensio…
Striking light-induced nonadiabatic fingerprint in the low-energy vibronic spectra of polyatomic molecules
Csaba Fábri, Benjamin Lasorne, Gábor J. Halász +2
Nonadiabaticity, i.e., the effect of mixing electronic states by nuclear motion, is a central phenomenon in molecular science. The strongest nonadiabatic effects arise due to the p…
Three-player polaritons: nonadiabatic fingerprints in an entangled atom-molecule-photon system
Tamás Szidarovszky, Gábor J. Halász, Ágnes Vibók
A quantum system composed of a molecule and an atomic ensemble, confined in a microscopic cavity, is investigated theoretically. The indirect coupling between atoms and the molecul…
Control of photodissociation with dynamic Stark effect induced by Thz pulses
A. Tóth, A. Csehi, G. J. Halász +1
We demonstrate how dynamic Stark control (DSC) can be achieved on molecular photodissociation in the dipole limit, using single-cycle (FWHM) laser pulses in the terahertz (THz) reg…
Rovibronic spectra of molecules dressed by light fields
Tamás Szidarovszky, Attila G. Császár, Gábor J. Halász +1
The theory of rovibronic spectroscopy of light-dressed molecules is presented within the framework of quantum mechanically treated molecules interacting with classical light fields…
Quantum Control with Quantum Light of Molecular Nonadiabaticity
András Csehi, Gábor J. Halász, Ágnes Vibók +1
Coherent control experiments in molecules are often done with shaped laser fields. The electric field is described classically and control over the time evolution of the system is…
