Theoretical Description of Coherent Doublon Creation via Lattice Modulation Spectroscopy
arXiv:1304.7802 · doi:10.1103/PhysRevA.89.021602
Abstract
Using a recently developed strong-coupling method, we present a comprehensive theory for doublon production processes in modulation spectroscopy of a three-dimensional system of ultracold fermionic atoms in an optical lattice with a trap. The theoretical predictions compare well to the experimental time traces of doublon production. For experimentally feasible conditions, we provide a quantitative prediction for the presence of a nonlinear "two-photon" excitation at strong modulation amplitudes.
