Compressed Sensing of Field-resolved Molecular Fingerprints Beyond the Nyquist Frequency
Kilian Scheffter, Jonathan Will, Claudius Riek +4
Ultrashort time-domain spectroscopy and field-resolved spectroscopy of molecular fingerprints are gold standards for detecting samples' constituents and internal dynamics. However,…
Application of FPGA based Lock-in amplifier for ultrasound propagation measurements using the pulse-echo technique
Stanislaw Galeski, Rafał Wawrzyńczak, Claudius Riek +1
We describe application of a state-of-the art digital FPGA based Lock-In amplifier to measurements of ultrasound propagation and attenuation at fixed frequency in low temperatures…
Subcycle Quantum Electrodynamics
Claudius Riek, Philipp Sulzer, Maximilian Seeger +4
Besides their stunning physical properties which are unmatched in a classical world, squeezed states of electromagnetic radiation bear advanced application potentials in quantum in…
Paraxial Theory of Direct Electro-Optic Sampling of the Quantum Vacuum
Andrey S. Moskalenko, Claudius Riek, Denis V. Seletskiy +2
Direct detection of vacuum fluctuations and analysis of sub-cycle quantum properties of the electric field are explored by a paraxial quantum theory of ultrafast electro-optic samp…
