Photoemission spectroscopy with high-intensity short-wavelength lasers
Song Bin Zhang, Nina Rohringer
We theoretically study the process of photoelectron emission of the Helium atom by a high-intensity short-wavelength laser at a resonance condition of the residual singly charged i…
Spin-Orbit Effects in Atomic High-Harmonic Generation
Stefan Pabst, Robin Santra
Spin-orbit interactions lead to small energy gaps between the outer-most and shells of noble gas atoms. Strong-field pulses tunnel-ionize an electron out of eit…
Introducing many-body physics using atomic spectroscopy
Dietrich Krebs, Stefan Pabst, Robin Santra
Atoms constitute relatively simple many-body systems, making them suitable objects for developing an understanding of basic aspects of many-body physics. Photoabsorption spectrosco…
Time delay in the recoiling valence-photoemission of Ar endohedrally confined in C
Gopal Dixit, Himadri S. Chakraborty, Mohamed El-Amine Madjet
Effects of confinement and electron correlations on the relative time delay between the 3s and 3p photoemissions of Ar confined endohedrally in C are investigated using the…
Strong-Field Many-Body Physics and the Giant Enhancement in the High-Harmonic Spectrum of Xenon
Stefan Pabst, Robin Santra
We resolve an open question about the origin of the giant enhancement in the high-harmonic generation (HHG) spectrum of atomic xenon around 100 eV. By solving the many-body time-de…
Recombination Amplitude Calculations of Noble Gases, in Length and Acceleration Forms, beyond Strong Field Approximation
Siddharth Bhardwaj, Sang-Kil Son, Kyung-Han Hong +3
Transition of an electron from a free to a bound state is critical in determining the qualitative shape of the spectrum in high-order harmonic generation (HHG), and in tomographic…
