Time-resolved Electron Momentum Spectroscopy with Ultrashort Electron Pulses: Confined Probing and Effects of Vacuum Dispersion
Pieter Hessel Harkema, Lars Bojer Madsen
Previous theoretical studies have shown that attosecond electron dynamics can, in principle, be captured in electron momentum spectroscopy (EMS) using ultrashort electron pulses. B…

Hilbert space fragmentation from lattice geometry
Pieter H. Harkema, Michael Iversen, Anne E. B. Nielsen
The eigenstate thermalization hypothesis describes how isolated many-body quantum systems reach thermal equilibrium. However, quantum many-body scars and Hilbert space fragmentatio…
