Quantum modified inertia: an application to galaxy rotation curves
Jonathan Gillot
This work explores modified inertia in the context of galactic dynamics by investigating the consequences of introducing bounds on acceleration. Building on earlier ideas related t…
Sub-kelvin measurement of silicon thermal expansion with a Fabry-Pérot cavity stabilized laser
Pierre Roset, Yara Hariri, Rémi Meyer +5
In this letter, we report the measurement of the coefficient of thermal expansion (CTE) of single-crystal silicon from 655 mK to 16 K using an ultra-stable laser based on a single-…
Development of a laser stabilized on an ultra-stable silicon cryogenic Fabry-Perot cavity for dark matter detection
Yara Hariri, Jacques Millo, Clément Lacroûte +3
Astrophysical observations suggest the existence of an unknown kind of matter in the Universe, in the frame of the CDM model. The research field of dark matter covers an energy…
Influence of a magnetic field on the frequency of a laser stabilized to molecular iodine
Jonathan Gillot, Joannes Barbarat, Charles Philippe +3
We report on the effect of a weak magnetic field applied on an iodine cell used to frequency stabilize a laser. A 1.5m laser is frequency tripled in order to excite the molecu…
Guidelines for designs for ultrastable laser with fractional frequency instability
Joannès Barbarat, Erik Benkler, Marcin Bober +46
Lasers with long coherence time and narrow linewidth are an essential tool for quantum sensors and clocks. Ultrastable cavities and laser systems are now commercially available wit…
