Complex and Heterogeneous Biophysical Systems Studied with 2DIR

When
-

Abstract: I will present three projects. In the first two, we used two-dimensional infrared (2DIR) spectroscopy to study properties of some complex peptide and protein assemblies 1: Proline-arginine (PR) dipeptide repeats are an example of a growing number of intrinsically disordered proteins (IDPs) known to assemble into membrane-less organelles by liquid-liquid phase separation (LLPS), and has also been implicated in the disease mechanism of Amyotrophic lateral sclerosis (ALS).

Heralded Spectroscopy - a new probe for nanocrystal multiexciton photophysics

When
-

Abstract:

Emitters of quantum light are at the core of quantum optic science and a key resource for emerging classical and quantum technologies. Yet, to date, the tools available to study multiple-photon quantum light sources, specifically temporally and spectrally in parallel, have been limited. A prominent example is multiply-excited semiconductor quantum dots - an intriguing system that features rich physics and technological potential but lacks direct observation techniques. 

Condensed Phase Isomerization through Tunneling Gateways

When
-

Abstract: Superconducting nanowire single-photon detectors (SNSPDs) provide sufficient sensitivity to enable laser induced fluorescence (LIF) experiments in the mid-infrared, an exciting technical development for studying molecule-surface interactions. In this talk, I will present results of experiments on the vibrational dynamics of monolayers and multilayers of solid CO adsorbed at the surface of a NaCl crystal that provide observations of quantum state resolved dynamics.
