Reduced density matrix description of high-harmonic generation in multi-electron atoms: exploring sub-cycle correlation effects
Katharina Buczolich, Takeshi Sato, Kenichi L. Ishikawa +3
High-harmonic generation (HHG) is one of the fundamental processes at the heart of attosecond physics. Traditionally viewed as an effective single-particle effect, recent advances…
Semiclassical strong-field theory of phase delays in above-threshold ionization
Diego G. Arbó, Sebastián D. López, Joachim Burgdörfer
Phase and time delays of atomic above-threshold ionization were recently experimentally explored in an setting [Zipp et al, Optica 1, 361 (2014)]. The phases of wavepackets…
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…
Circular holographic ionization-phase meter
Stefan Donsa, Nicolas Douguet, Joachim Burgdörfer +2
We propose an attosecond XUV-pump IR-probe photoionization protocol that employs pairs of counter-rotating consecutive harmonics and angularly resolved photoelectron detection, the…
Polarization tagging of two-photon double ionization by elliptically polarized XUVs
Stefan Donsa, Iva Brezinova, Hongcheng Ni +2
We explore the influence of elliptical polarization on the (non)sequential two-photon double ionization of atomic helium with ultrashort extreme ultraviolet (XUV) light fields usin…
Rydberg-Blockade Effects in Autler-Townes Spectra of Ultracold Strontium
B. J. DeSalvo, J. A. Aman, C. Gaul +6
We present a combined experimental and theoretical study of the effects of Rydberg interactions on Autler-Townes spectra of ultracold gases of atomic strontium. Realizing two-photo…
