All-optical logic gates for extreme ultraviolet switching via attosecond four-wave mixing
Patrick Rupprecht, Daniel M. Neumark, Stephen R. Leone
All-optical logic-gate-based switching is a prerequisite for photonic computing. This article introduces a logic-gate protocol for noncollinear four-wave mixing (FWM) of one attose…
Versatile, open-source program for simulating high-harmonic generation
Christian A. Schröder, Reinhard Kienberger, Stephen R. Leone
Light sources based on high-harmonic generation (HHG) underpin ultrafast spectroscopy experiments across a large range of photon energies, spanning from the extreme-ultraviolet to…
Tracing long-lived atomic coherences generated via molecular conical intersections
Patrick Rupprecht, Francesco Montorsi, Lei Xu +7
Accessing coherences is key to fully understand and control ultrafast dynamics of complex quantum systems like molecules. Most photochemical processes are mediated by conical inter…
Extracting doubly-excited state lifetimes in helium directly in the time domain with attosecond noncollinear four-wave-mixing spectroscopy
Patrick Rupprecht, Nicolette G. Puskar, Daniel M. Neumark +1
The helium atom, with one nucleus and two electrons, is a prototypical system to study quantum many-body dynamics. Doubly-excited states, or quantum states in which both electrons…
Attosecond transient grating spectroscopy with near-infrared grating pulses and an extreme ultraviolet diffracted probe
Rafael Quintero-Bermudez, Lorenz Drescher, Vincent Eggers +2
Transient grating spectroscopy has become a mainstay among metal and semiconductor characterization techniques. Here we extend the technique towards the shortest achievable timesca…
Initial electron thermalization in metals measured by attosecond transient absorption spectroscopy
Bethany R. de Roulet, Lorenz Drescher, Shunsuke A. Sato +1
Understanding initial electron thermalization has relevance to both fundamental scientific knowledge and application to the construction of novel devices. In this study, attosecond…
