- Abstract: We analytically tackle opto-vibronic interactions in molecular systems driven
by either classical or quantum light fields. In particular, we examine a simple
model of molecules with two relevant electronic levels, characterized by
potential landscapes with different positions of minima along the internuclear
coordinate and of varying curvatures. Such systems exhibit an electron-vibron
interaction, which can be comprised of linear and quadratic terms in the
vibrational displacement. By employing a combination of conditional
displacement and squeezing operators, we present analytical expressions based
on a quantum Langevin equations approach, to describe the emission and
absorption spectra of such nonlinear molecular systems. Furthermore, we examine
the imprint of the quadratic interactions onto the transmission properties of a
cavity-molecule system within the collective strong coupling regime of cavity
quantum electrodynamics.
