Theory of high-energy correlated multiphoton x-ray diffraction for synchrotron radiation sources
Arunangshu Debnath, Robin Santra
We present a theoretical formulation for the multiphoton diffraction phenomenology in the nonrelativistic limit, suitable for interpreting high-energy x-ray diffraction measurement…
Multiple-core-hole resonance spectroscopy with ultraintense X-ray pulses
Aljoscha Rörig, Sang-Kil Son, Tommaso Mazza +14
Understanding the interaction of intense, femtosecond X-ray pulses with heavy atoms is crucial for gaining insights into the structure and dynamics of matter. One key aspect of non…
Theoretical investigation of orbital alignment of x-ray-ionized atoms in exotic electronic configurations
Laura Budewig, Sang-Kil Son, Robin Santra
We theoretically study orbital alignment in x-ray-ionized atoms and ions, based on improved electronic-structure calculations starting from the Hartree-Fock-Slater model. We employ…
State-resolved ionization dynamics of neon atom induced by x-ray free-electron-laser pulses
Laura Budewig, Sang-Kil Son, Robin Santra
We present a theoretical framework to describe state-resolved ionization dynamics of neon atoms driven by ultraintense x-ray free-electron-laser pulses. In general, x-ray multiphot…
Resonance-enhanced multiphoton ionization in the x-ray regime
Aaron C. LaForge, Sang-Kil Son, Debadarshini Mishra +16
Here, we report on the nonlinear ionization of argon atoms in the short wavelength regime using ultraintense x rays from the European XFEL. After sequential multiphoton ionization,…
Transient ionization potential depression in nonthermal dense plasmas at high x-ray intensity
Rui Jin, Malik Muhammad Abdullah, Zoltan Jurek +2
The advent of x-ray free-electron lasers (XFELs), which provide intense ultrashort x-ray pulses, has brought a new way of creating and analyzing hot and warm dense plasmas in the l…
