Nonlinear reversal of photo-excitation on the attosecond time scale improves ultrafast x-ray diffraction images
Anatoli Ulmer, Phay J. Ho, Bruno Langbehn +28
The advent of isolated and intense sub-femtosecond X-ray pulses enables tracking of quantummechanical motion of electrons in molecules and solids. The combination of X-ray spectros…
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…
X-ray induced electron and ion fragmentation dynamics in IBr
Phay J. Ho, Dipanwita Ray, Stefan Lehmann +9
Characterization of the inner-shell decay processes in molecules containing heavy elements is key to understanding x-ray damage of molecules and materials and for medical applicati…
Resonant Double-Core Excitations with Ultrafast, Intense Pulses
Adam E. A. Fouda, Dimitris Koulentianos, Linda Young +2
Intense few-to-sub-femtosecond soft x-ray pulses can produce neutral, two-site excited double-core-hole states by promoting two core electrons to the same unoccupied molecular orbi…
