Correlated noise enhances coherence and fidelity in coupled qubits
Eric R Bittner, Hao Li, Syad A. Shah +2
It is generally assumed that environmental noise arising from thermal fluctuations is detrimental to preserving coherence and entanglement in a quantum system. In the simplest sens…
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…
Identifying incoherent mixing effects in the coherent two-dimensional photocurrent excitation spectra of semiconductors
Ilaria Bargigia, Elizabeth Gutiérrez-Meza, David A. Valverde-Chávez +3
We have previously demonstrated that in the context of two-dimensional (2D) coherent electronic spectroscopy measured by phase modulation and phase-sensitive detection, an \emph{in…
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…
Concerning the stability of hybrid biexcitons in organic polymer aggregates
Eric R. Bittner, Carlos Silva-Acuna
Frenkel excitons are the primary photoexcitations in organic semiconductors and are ultimately responsible for the optical properties of such materials. They are also predicted to…
