QFARM Spotlight on Marsh
What first got you excited about science? Mostly science fiction, to be honest! I was a big star wars nerd growing up and my dad really liked watching shows about black holes and the universe. I always thought…

Pairing atoms in 1D with photons
New theory paper in PRL shows how to use photon-mediated interactions in a multimode optical cavity to induces a peierls transition in a 1D Bose or Fermi gas. The transition is to a paired state that creates a…
Dynamical Spin-Orbit Coupling
We demonstrated dynamical spin-orbit-coupling in a BEC for the first time using an optical cavity. The resulting state is a spinor-helix polarition condensate. Paper appeared in PRL.
