Measuring the eccentricity of the Earth orbit with a nail and a piece of plywood
Thierry Lahaye
I describe how to obtain a rather good experimental determination of the eccentricity of the Earth orbit, as well as the obliquity of the Earth rotation axis, by measuring, over th…
Matter wave scattering on an amplitude-modulated optical lattice
Pierrick Cheiney, Charlotte Fabre, François Vermersch +4
We experimentally study the scattering of guided matter waves on an amplitude-modulated optical lattice. We observe different types of frequency-dependent dips in the asymptotic ou…
Fizeau's "aether-drag" experiment in the undergraduate laboratory
Thierry Lahaye, Pierre Labastie, Renaud Mathevet
We describe a simple realization of Fizeau's "aether-drag" experiment. Using an inexpensive setup, we measure the phase shift induced by moving water in a laser interferometer and…
