Thanks.
Great to be here.
Okay.
Yes, so um it's a very special atom interferometer.
So maybe I should start by explaining what an atom interferometer is.
So um well uh a regular interferometer you have a a photon and you pass it through what we call a BIM splitter, uh which lets the photon uh go through one trajectory and then
Another it's reflected by some mirrors and then in another beam splitter which is cr a crystal that um um allows the
the two paths to interfere and then at the output of the interferometer you see uh interference fringes and uh with a certain um contrast and and so on.
So uh black and white interference uh uh fringes typical from a wave uh propagation in the interferometer.
So another
Interferometer is kind of the same thing, but instead of using photons, is using atoms.
And well one of the things that I find really beautiful about light and matter interactions is that if you have the um atoms being uh
Interfered, but it's not a good thing.
Instead of one uses like a crystal to interfere with
phot photons you use laser fields so light field to make like the to play the role of the beam splitter for the atoms and so on.
So a regular uh atom interferometer you would have atoms arriving to the laser that splits the atom.
So the atom goes
itself in a superposition of two different trajectories.
It gets reflected again instead of mirrors there are fields that uh reflected back so that they can interfere again at another
um laser and then you can detect the the output uh and so on.
