SUMMARY:CCB Seminar: Hsing-ta [Theta] Chen (Notre Dame)
LOCATION:Baker Lab 119\, 259 East Ave\, Ithaca\, NY 14850\, USA
DESCRIPTION:"Navigating Various Disorders and Dynamics in Strongly Coupled
  Light-Matter Systems"\n\nAbstract:\nStrong light-matter interactions hol
 d great promise for modulating molecular and material properties\, includ
 ing chemical reactivity\, energy transfer\, and charge conductivity\, via
  polaritonic states. In realistic chemical and material systems\, disorde
 r arising from thermal fluctuations and structural defects is inevitable 
 and has a significant impact on the polaritonic state. However\, disorder
  is often considered a perturbative effect and is usually omitted from mo
 dels of\nlight-matter dynamics and spectroscopy. In this talk\, I aim to 
 explore dynamical simulations of strongly coupled systems under various f
 orms of disorder\, including random dipole orientations\, electromagnetic
  field fluctuations\, and electron-phonon coupling. Contrary to the intui
 tion that disorder inherently hinders exciton transport and suppresses st
 rong coupling phenomena\, our findings suggest that disorder can actually
  facilitate access to hidden degrees of freedom\, specifically optical da
 rk states. We demonstrate how these states can be leveraged to modulate e
 xciton transport properties and introduce unique spectroscopic signatures
