Entangled photon pair excitation and time-frequency-filtered multidimensional photon correlation spectroscopy as a probe for dissipative exciton kinetics
Arunangshu Debnath, Shaul Mukamel
The paper proposes using entangled photon pairs for narrowband excitation of two‑exciton states and time‑frequency‑filtered two‑photon coincidence detection to resolve dissipative…
Photon entanglement-enhanced multidimensional spectroscopy of exciton correlations in photosynthetic aggregates
Arunangshu Debnath, Shaul Mukamel
Nonlinear spectroscopic techniques using entangled photon pairs can provide an opportunity to exploit non-classical correlations encoded in two-photon wavefunctions to manipulate t…
Tracing long-lived atomic coherences generated via molecular conical intersections
Patrick Rupprecht, Francesco Montorsi, Lei Xu +7
Accessing coherences is key to fully understand and control ultrafast dynamics of complex quantum systems like molecules. Most photochemical processes are mediated by conical inter…
Pump-intensity-scaling of Two-Photon-Absorption and Photon Statistics of Entangled-Photon Fields
Deependra Jadoun, Upendra Harbola, Vladimir Y. Chernyak +1
We use a non-perturbative theoretical approach to the parametric down-conversion (PDC) process, which generates entangled-photon field for an arbitrarily strong pump-pulse. This ap…
Two-dimensional spectroscopy of open quantum systems
Haoran Sun, Upendra Harbola, Shaul Mukamel +1
Two-dimensional spectroscopy is discussed for open quantum systems with multiple simultaneously measurable fluxes. In particular, we discuss a junction where optical measurements o…
Nonlinear optical spectroscopy of open quantum systems
Haoran Sun, Upendra Harbola, Shaul Mukamel +1
Development of experimental techniques at nanoscale resulted in ability to perform spectroscopic measurements on single-molecule current carrying junctions. These experiments are n…
