LISA forecasts for quadratically coupled ultralight dark matter show competitive or superior sensitivity to terrestrial and astrophysical probes in selected mass windows, free of screening.
Demonstration of record conversion efficiency for a 148 nm VUV frequency comb using 16th-harmonic generation in a bulk-grown QPM crystal.
Ultralight dark matter induces oscillating CKM elements that can be probed at NA62 through direct counting of meson decay events, which avoids sensitivity loss from unknown particle flux.
Nuclear DFT calculations determine the B(M1) transition strength between the 3/2+ ground and 5/2+ isomeric states in 229Th and report favorable agreement with experiment without parameter adjustment.
A review of 229Th isomer spectroscopy, clock platforms, nuclear-structure models, and fundamental-physics applications, with an additional mean-field check of the octupole minimum.
Colloquium overview of Th-229 nuclear clock development, covering its nuclear physics basis, recent direct laser excitation, clock design and systematics in traps and solids, and sensitivity to fundamental constant variations.
