Dynamical quasi-condensation in the weakly interacting Fermi-Hubbard model
Iva Březinová, Markus Stimpfle, Stefan Donsa +1
We study dynamical (quasi)-condensation in the Fermi-Hubbard model starting from a completely uncorrelated initial state of adjacent doubly occupied sites. We show that upon expans…
Non-equilibrium correlation dynamics in the one-dimensional Fermi-Hubbard model: A testbed for the two-particle reduced density matrix theory
Stefan Donsa, Fabian Lackner, Joachim Burgdörfer +4
We explore the non-equilibrium dynamics of a one-dimensional Fermi-Hubbard system as a sensitive testbed for the capabilities of the time-dependent two-particle reduced density mat…
Zeptosecond Angular Streak Camera
Hongcheng Ni, Stefan Donsa, Xiaochun Gong +3
Time-resolved electronic processes on the attosecond scale have recently become experimentally accessible through the development of laser-based pump-probe interrogation techniques…
Phase delays in above-threshold ionization
S. D. López, S. Donsa, S. Nagele +2
Relative phases of atomic above-threshold ionization wavepackets have been investigated in a recent experiment [L. J. Zipp, A. Natan, and P. H. Bucksbaum, Optica \textbf{1}, 361-36…
Canonical density matrices from eigenstates of mixed systems
Mahdi Kourehpaz, Stefan Donsa, Fabian Lackner +2
One key issue of the foundation of statistical mechanics is the emergence of equilibrium ensembles in isolated and closed quantum systems. Recently, it was predicted that in the th…
Towards the complete phase profiling of attosecond wave packets
Jaco Fuchs, Nicolas Douguet, Stefan Donsa +5
Realistic attosecond wave packets have complex profiles that, in dispersive conditions, rapidly broaden or split into multiple components. Such behaviors are encoded in sharp featu…
