Caustics and catastrophes in strong-field physics -- Picard--Lefschetz theory as a universal approach to saddle-point methods in attosecond science
Anne Weber
Ultrashort laser pulses on the attosecond timescale are typically achieved via high-order harmonic generation (HHG), a nonlinear process in which atoms interact with intense light…
2D quantum-path interference in high-harmonic generation driven by highly-bichromatic fields
Xiaozhou Zou, Lucie JurkoviÄová, Anne Weber +12
We experimentally observe a new type of quantum-path interference, in two-dimensions (2D-QPI), in high-harmonic generation (HHG) driven by an orthogonally-polarised highly-bichroma…
A universal approach to saddle-point methods in attosecond science
Anne Weber, Job Feldbrugge, Emilio Pisanty
Light-matter interactions within the strong-field regime, where intense laser fields can ionise a target via tunnelling, give rise to fascinating phenomena such as the generation o…
Quantum tunnelling without a barrier
Anne Weber, Margarita Khokhlova, Emilio Pisanty
Tunneling is an iconic concept that captures the peculiarity of quantum dynamics but, despite its ubiquity, questions remain. We focus on strong-field tunneling, which is vital to…
