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,…
Attosecond Coherent Electron Motion in Auger-Meitner Decay
Siqi Li, Taran Driver, Philipp Rosenberger +38
In quantum systems, coherent superpositions of electronic states evolve on ultrafast timescales (few femtosecond to attosecond, 1 as = 0.001 fs = 10^{-18} s), leading to a time dep…
