In the framework of the Hubbard model, it is shown that approximate dynamic localization for strongly correlated electrons hopping on a one-dimensional lattice and driven by a high-frequency sinusoidal field can be realized provided that periodic pi phase slips are impressed into the sinusoidal field. A possible experimental demonstration of the proposed driving scheme is presented for a photonic model system of the two-particle Hubbard model, based on light transport in a square waveguide lattice with a sinusoidally curved optical axis.

Abstract
In the framework of the Hubbard model, it is shown that approximate dynamic localization for strongly correlated electrons hopping on a one-dimensional lattice and driven by a high-frequency sinusoidal field can be realized provided that periodic pi phase slips are impressed into the sinusoidal field. A possible experimental demonstration of the proposed driving scheme is presented for a photonic model system of the two-particle Hubbard model, based on light transport in a square waveguide lattice with a sinusoidally curved optical axis.File in questo prodotto:
