Circular RABBITT goes under threshold
Vladislav V. Serov, Jia-Bao Ji, Meng Han +3
We introduce circular under-threshold RABBITT (cuRABBITT) as a new interferometric method to probe discrete electronic excitations in atoms with attosecond resolution. By combining…
Attosecond X-ray Core-level Chronoscopy of Aromatic Molecules
Jia-Bao Ji, Zhaoheng Guo, Taran Driver +32
Attosecond photoemission or photoionization delays are a unique probe of the structure and the electronic dynamics of matter. However, spectral congestion and spatial delocalizatio…
Photoionization time delays probe electron correlations
Mingxuan Li, Huiyong Wang, Rezvan Tahouri +16
The photoelectric effect, explained by Einstein in 1905, is often regarded as a one-electron phenomenon. However, in multi-electron systems, the interaction of the escaping electro…
Analytical Expression for Continuum-continuum Transition Amplitude of Hydrogen-like Atoms with Angular-momentum Dependence
Jia-Bao Ji, Kiyoshi Ueda, Meng Han +1
Attosecond chronoscopy typically utilises interfering two-photon transitions to access the phase information. Simulating these two-photon transitions is challenging due to the cont…
