THE PHYSICS GRADUATE PROGRAM invites everyone to the seminar:

Chemistry in optical microcavities: Spectral fluctuations and energy transport

Prof. Dr. Raphael Ribeiro

Department of Chemistry, Emory University – Atlanta, USA


Optical cavities and metallic nanoparticles confine electromagnetic fields and enable new pathways to control physicochemical processes via strong light-matter interactions. In fact, recent experiments have shown that photonic and plasmonic materials may induce significant and sometimes unexpected changes to physical properties and reactivity of molecular systems. In this talk, I will introduce and present the key results of our recent theoretical investigations on the effects of collective radiation-matter interactions on transport and spectral properties of disordered molecular ensembles hosted by a resonant 1D optical cavity (photonic wire). The main implications of our findings to future theoretical and experimental research will be discussed. I will show that widely employed minimal theoretical models fail to adequately describe photonic effects on the local properties of chemical systems and explain strategies to maximize the influence of optical cavities on molecular materials informed by our simulations.

Date: November 19, 2021 – (friday) – Time: 10:15 a.m.
