X-ray diffraction from chiral molecules with twisted beams
Akilesh Venkatesh, Phay J. Ho, Jérémy R. Rouxel
Structured x-rays carrying an orbital angular momentum break spatial inversion symmetry and have been proposed as probes of chirality. We theoretically investigate twisted non-reso…
Quantum Interference in Two-Atom Resonant X-ray Scattering of an Intense Attosecond Pulse
Akilesh Venkatesh, Phay J. Ho
We theoretically investigate resonant x-ray scattering from two non-interacting Ne+ ions driven by an intense attosecond pulse using a non-relativistic, QED-based time-dependent fr…
Effect of Rabi dynamics in resonant x-ray scattering of intense attosecond pulses
Akilesh Venkatesh, Phay J. Ho
We theoretically study the effects of Rabi oscillations on resonant x-ray scattering in Ne using intense attosecond and few-femtosecond pulses. The total photon yield strongly…
Theory of resonant x-ray scattering with ultrafast intense pulses
Akilesh Venkatesh, Phay J. Ho
We present a time-dependent Schrödinger equation (TDSE) approach within a non-relativistic quantum electrodynamics (QED) framework to investigate resonant x-ray scattering under in…
Simulations for x-ray imaging of wave-packet dynamics
Akilesh Venkatesh, F. Robicheaux
Previous work on imaging wave packet dynamics with x-ray scattering revealed that the scattering patterns deviate substantially from the notion of instantaneous momentum density of…
Interference in nonlinear Compton scattering using a Schrödinger's equation approach
Akilesh Venkatesh, F. Robicheaux
The interference between Compton scattering and nonlinear Compton scattering from a two-color field in the X-ray regime is theoretically examined for bound electrons. The underlyin…
The effect of orientation of Rydberg atoms on their collisional ionization cross section
Akilesh Venkatesh, Francis Robicheaux
Collisional ionization between two Rydberg atoms in relative motion is examined. A classical trajectory Monte Carlo method is used to determine the cross sections associated with P…
Simulation of nonlinear Compton scattering from bound electrons
Akilesh Venkatesh, Francis Robicheaux
Recent investigations by Fuchs et al. [Nat. Phys. 11, 964 (2015)] revealed an anomalous frequency shift in non-linear Compton scattering of high-intensity X-rays by electrons in so…
