QuDPy: A Python-Based Tool For Computing Ultrafast Non-linear Optical Responses
S. A. Shah, Hao Li, Eric R. Bittner +2
Nonlinear Optical Spectroscopy is a well-developed field with theoretical and experimental advances that have aided multiple fields including chemistry, biology and physics. Howeve…
The Optical Signatures of Stochastic Processes in Many-Body Exciton Scattering
Hao Li, S. A. Shah, Ajay Ram Srimath Kandada +3
We review our recent quantum stochastic model for spectroscopic lineshapes in the presence of a co-evolving and non-stationary background population of excitations. Starting from a…
Stochastic exciton-scattering theory of optical lineshapes: Renormalized many-body contributions
Hao Li, S. A. Shah, Eric R. Bittner +2
Spectral line-shapes provide a window into the local environment coupled to a quantum transition in the condensed phase. In this paper, we build upon a stochastic model to account…
Correlating exciton coherence length, localization, and its optical lineshape. I. a finite temperature solution of the Davydov soliton model
Eric R. Bittner, Carlos Silva, S. A. Shah +1
The lineshape of spectroscopic transitions offer windows into the local environment of a system. Here, we present a novel approach for connecting the lineshape of a molecular excit…
