Electronic Strong Coupling of Gas-Phase Molecular Iodine
Jane C. Nelson, Trevor H. Wright, Neo Lin +2
Molecular polaritons, hybrid light-matter states formed from the strong coupling of molecular transitions and discrete photonic modes, are a compelling platform for optical control…
Tracking water vapor homogeneous nucleation and droplet growth with spectroscopy and holography in a free expansion cloud chamber
Cole R. Sagan, Gwenore F. Pokrifka, Samuel M. Koblensky +5
We use a newly commissioned rapid expansion aerosol chamber (REACh) facility to study the homogeneous nucleation of water vapor to form liquid droplets. We perform high-speed measu…
Nonlinear signal enhancement of strongly-coupled molecules in pump-probe experiments
Alexander M. McKillop, Marissa L. Weichman
Nonlinear spectroscopy is widely used to study the transient dynamics of molecules under strong light-matter coupling, though it remains unclear to what extent uncoupled intracavit…
Long-wave mid-infrared cavity-enhanced frequency comb spectroscopy of cold, complex molecules
Negar Baradaran, Dominik Charczun, Tanay Nambiar +4
We report the development of a new instrument for cavity-enhanced absorption spectroscopy of the fundamental rovibrational transitions of molecules in the long-wave mid-infrared (L…
Direct readout of excited state lifetimes in chlorin chromophores under electronic strong coupling
Alexander M. McKillop, Liying Chen, Ashley P. Fidler +1
The mechanisms governing molecular photophysics under electronic strong coupling (ESC) remain elusive to date. Here, we use ultrafast pump-probe spectroscopy to study the nonradiat…
Ultrafast optical modulation of vibrational strong coupling in ReCl(CO)(2,2-bipyridine)
Liying Chen, Alexander M. McKillop, Ashley P. Fidler +1
Polaritons - hybrid light-matter states formed from the strong coupling of a bright molecular transition with a confined photonic mode - may offer new opportunities for optical con…
