A thorium-229 optical nuclear clock with feedback loop

Abstract The laser-accessible nuclear transition in the thorium-229 isotope has been identified as a candidate for realizing an optical nuclear clock 1 that might outperform current optical clocks based on electron-shell transitions in atoms or ions 2 . It is expected to be more...

Strain rate effect on frictional behaviour of Hardox 450 steel

Abstract The influence of strain rate on the frictional behaviour of high-strength Hardox 450 steel have been investigated using both experimental and numerical approaches. The ring compression test method was employed to identify the friction coefficient across a wide range of s...

Qubit-parity interference despite unknown interaction phases

Abstract Quantum interference between interacting systems is fundamental to basic science and quantum technology, but it typically requires precise control of the interaction phases of lasers or microwave generators. Can interference be observed if those interaction phases are st...
