Electron Correlation Enables Phase-Coherent One-Attosecond Pulse Trains
Andrés Marchisio, Isobel McSweeney, Paraskevas Tzallas +2
Attosecond synthesis is ultimately a phase problem: a broad spectrum produces an ultrashort waveform only if its harmonics remain phase-locked. We show theoretically that correlate…

Scalable Size- and Shape-Selective Purification of Colloidal Building Blocks via Excluded Volume Interactions
Thomas Kainz, Isobel McSweeney, Andrei-Micea Top +4
Excluded-volume interactions, arising solely from steric constraints, play a crucial role in determining the structure, dynamics, and phase behaviour of colloidal suspensions. This…

Two-Electron Effects Extend High-Harmonic Generation into the keV Regime
Isobel McSweeney, Andres Marchisio, Javier Rivera-Dean +4
Two-electron processes can generate high harmonics beyond the conventional single-active-electron cutoff. Motivated by recent experimental evidence of an extended secondary plateau…
