Inducing Transport in a Dissipation-Free Lattice with Super Bloch Oscillations
Inducing Transport in a Dissipation-Free Lattice with Super Bloch Oscillations
Particles in a perfect lattice potential perform Bloch oscillations when subject to a constant force, leading to localization and preventing conductivity. For a weakly-interacting Bose-Einstein condensate (BEC) of Cs atoms, we observe giant center-of-mass oscillations in position space with a displacement across hundreds of lattice sites when we add a …
