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…
Entangled photon pair excitation and time-frequency-filtered multidimensional photon correlation spectroscopy as a probe for dissipative exciton kinetics
Arunangshu Debnath, Shaul Mukamel
In quantum aggregates, delocalized exciton states across energy manifolds interact with phonon modes, making state-resolved spectroscopic monitoring of dynamics challenging. We pro…
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…
Stimulated X-ray Raman scattering for selective preparation of dark states bypassing optical selection rules
Francesco Montorsi, Shaul Mukamel, Filippo Tamassia +3
We present an X-ray based stimulated Raman approach to control the preparation of optically dark electronic states in generic molecular systems. Leveraging on the unique properties…
Ultrafast photochemistry and electron-diffraction spectra in n->(3s) Rydberg excited cyclobutanone resolved at the multireference perturbative level
V. K. Jaiswal, F. Montorsi, F. Aleotti +6
We study the ultrafast time evolution of cyclobutanone excited to singlet n-->Rydberg state through XMS-CASPT2 nonadiabatic surface-hopping simulations. These dynamics predict rela…
Probing chirality fluctuations in molecules by nonlinear optical spectroscopy
N. Mann, P. Nalbach, S. Mukamel +1
Symmetry breaking caused by geometric fluctuations can enable processes that are otherwise forbidden. An example is a perylene bisimide dyad whose dipole moments are perpendicular…
Reconstruction of the wavefunctions of coupled nanoscopic emitters using a coherent optical technique
M. Richter, F. Schlosser, M. Schoth +4
We show that using coherent, spatially resolved spectroscopy, complex hybrid wave functions can be disentangled into the individual wave functions of the individual emitters. This…
Many-body Green's function approach to attosecond nonlinear X-ray spectroscopy
U. Harbola, S. Mukamel
Closed expressions are derived for resonant multidimensional X-ray spectroscopy using the quasiparticle nonlinear exciton representation of optical response. This formalism is appl…
