Expérimental et théorique
Optical lattice clocks have reached such a resolution that they can now be controlled at the 18 digits level. This makes them able to detect a change of height of 1 cm, via a general relativity effect called gravitational time dilation. At SYRTE, Observatoire de Paris, we are building a transportable Ytterbium lattice clock, targeting ultrahigh stability, in order to participate to the cartography of the geopotential in the future. The M2 student will work on the construction of the so-called 'magic' optical lattice, and on the loading techniques to catch atoms efficiently in this trap.
