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…
Many-Exciton Quantum Dynamics in a Ruddlesden-Popper Tin Iodide
Esteban Rojas Gatjens, Hao Li, Alejandro Vega Flick +5
We present a study on the many-body exciton interactions in a prototype Ruddlesden-Popper metal halide (RPMH), namely \ce{(PEA)2SnI4} (PEA = phenylethylammine), using coherent two-…
Multidimensional coherent spectroscopy of excitons in -conjugated polymers
Elizabeth Gutiérrez-Meza, Alejandro Vega-Flick, Eric R. Bittner +1
The photophysics of -conjugated polymers has been of considerable interest over the last three decades because of their organic semiconductor properties. Primary photoexcitation…
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…
