Description
I will discuss a novel platform for compact, continuously-trapped atom interferometry using lithium Bose condensates in the Floquet-Bloch bands of an amplitude-modulated optical lattice. In analogy to the magic wavelengths employed by optical lattice clocks, we theoretically identify and experimentally realize magic band structures for which the interferometric phase is insensitive to noise in the trapping lattice intensity. Time permitting, I will also touch on related experiments in driven quantum matter, probing phenomena ranging from kicked quasicrystals to quantum chaos and interactive dynamics.
