A swept-source dual-comb spectrometer on a chip
Johannes Fuchsberger, Theodore P. Letsou, Paul Chevalier +4
Dual-comb spectroscopy (DCS) enables high-speed, high-resolution spectroscopy by down-converting optical spectra to the radio-frequency (RF) domain through the interference of two…

When Do Concepts Become Functionally Sufficient During Language-Model Training?
Raphael Bernas, Paul G. Chevalier, Fanny Jourdan +1
Understanding a model and its learning mechanisms in depth requires identifying when its internal structures become useful, rather than simply looking at the final state. We study…

A scalable platform for nanometer-scale quantum confinement
Christina M. Spaegele, Mehdi Rezaee, Thomas Werkmeister +8
Overcoming the limitations of current nanofabrication techniques to achieve nanoscale feature sizes is essential for achieving new regimes of light-matter interactions at extreme f…
