The coherent motion of few correlated particles in Hubbard models shows rather distinctive dynamical features that go beyond the predictions of mean-field (NLSE) models. In this contribution we will discuss the dynamical properties of strongly correlated particles forming a bound particle state (doublons) driven by external forces, including the existence of fractional Bloch oscillations, the coherent destruction of particle correlation, super-Bloch and anyonic Bloch oscillations, Klein tunneling of correlated particles and low-excitation bound states in ac-driven two-species Hubbard models. Photonic simulations of fractional Bloch oscillations in a waveguide-based optical setting will be also presented.

Abstract
The coherent motion of few correlated particles in Hubbard models shows rather distinctive dynamical features that go beyond the predictions of mean-field (NLSE) models. In this contribution we will discuss the dynamical properties of strongly correlated particles forming a bound particle state (doublons) driven by external forces, including the existence of fractional Bloch oscillations, the coherent destruction of particle correlation, super-Bloch and anyonic Bloch oscillations, Klein tunneling of correlated particles and low-excitation bound states in ac-driven two-species Hubbard models. Photonic simulations of fractional Bloch oscillations in a waveguide-based optical setting will be also presented.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
