• Abstract: We introduce an effective modes formalism to describe how the quasi-continuum of photonic modes in an optical cavity effectively behaves in the strong light-matter coupling regime of cavity quantum electrodynamics. By expressing these effective modes, we are able to show that the mode volumes of these effective modes are independent of the physical area of the Fabry-P\'erot cavity mirrors. Further, our theoretical framework shows that the photonic density of state for a Fabry-P\'erot exhibits a sharp peak at the normal incidence and is quality factor dependent. These results provide a possible explanation for the recently discovered experimental phenomenon in vibrational polaritons, where chemical reactivities can only be modified if the molecules are coupled in resonance to the normal-incidence mode in a Fabry-P\'erot cavity.

The dependence of the spectral function on the time after the pump pulse reveals collective interactions among spinons.

A thorough study of the mode-splitting and its tuning across the stop-band leads to a quantitative understanding of the mechanism behind the results.

This allows us to explore the full range of subdiffusive behaviors, ranging from anomalous Anderson localization to normal diffusion.

  We study the dynamical Casimir effect of the optomechanical cavity interacting with one-dimensional photonic crystal. The quantum vacuum fluctuation of the intra-cavity mode is parametrically amplified by a periodic motion of the mirror boundary. We have found that the nonlocal stationary eigenmode appears when the mixing between the cavity mode and the photonic band is caused by the indirect virtual transition.

  We show that as more photon modes are accounted for, physico-chemical phenomena can dramatically change. As the number of cavity photon modes increases, the increasing deviation of these surfaces from the cavity-free Born-Oppenheimer surfaces, together with the interplay between photon emission and absorption inside the widening bands of these surfaces, leads to enhanced suppression.
