Attosecond screening dynamics mediated by electron-localization
M. Volkov, S. A. Sato, F. Schlaepfer +6
Transition metals with their densely confined and strongly coupled valence electrons are key constituents of many materials with unconventional properties, such as high-Tc supercon…
Role of intra-band transitions in photo-carrier generation
Shunsuke A. Sato, Matteo Lucchini, Mikhail Volkov +4
We theoretically investigate the role of intra-band transitions in laser-induced carrier-generation for different photon energy regimes: (i) strongly off-resonant, (ii) multi-photo…
Ptychographic reconstruction of attosecond pulses
M. Lucchini, M. H. Brügmann, A. Ludwig +3
We demonstrate a new attosecond pulse reconstruction modality which uses an algorithm that is derived from ptychography. In contrast to other methods, energy and delay sampling are…
Time delay anisotropy in photoelectron emission from the isotropic ground state of helium
Sebastian Heuser, Álvaro Jiménez Galán, Claudio Cirelli +11
Time delays of electrons emitted from an isotropic initial state and leaving behind an isotropic ion are assumed to be angle-independent. Using an interferometric method involving…
Resonance effects in photoemission time delays
M. Sabbar, S. Heuser, R. Boge +6
We present measurements of single-photon ionization time delays between valence electrons of argon and neon using a coincidence detection technique that allows for the simultaneous…
Multiphoton transitions for delay-zero calibration in attosecond spectroscopy
Jens Herrmann, Matteo Lucchini, Shaohao Chen +7
The exact delay-zero calibration in an attosecond pump-probe experiment is important for the correct interpretation of experimental data. In attosecond transient absorption spectro…
