Dynamical modulation of Optical lattices studied by a numerical investigation on response theory

ORAL

Abstract

The response to the dynamical modulation of optical lattice potentials is studied by Determinantal Quantum Monte Carlo combined with the Maximum Entropy method. We simulate three and two-dimensional repulsive fermionic Hubbard models within the strong coupling regime and near half-filling for a wide range of temperatures. We discuss the relation between the first and second order response \% to the dynamical modulation and the dynamical generated double occupancy and the relevance of bond order excitations near half-filling.
