Superfluid Quasicrystals
Azimuth 2020-02-01
Summary:
Condensed matter physics is so cool! Bounce 4 laser beams off mirrors to make an interference pattern with 8-fold symmetry. Put a Bose–Einstein condensate of potassium atoms into this “optical lattice” and you get a superfluid quasicrystal! You see, no periodic pattern in the plane can have 8-fold symmetry, so the interference pattern of the […]
