Field-induced ferromagnetism in one-dimensional tight-binding lattices
Giuseppe Della Valle, Stefano Longhi
We theoretically show the possibility to induce magnetic ordering in non-magnetic one-dimensional systems of strongly interacting electrons hopping on a tight-binding lattice. Our…
Low-energy doublons in the ac-driven two-species Hubbard model
S. Longhi, G. Della Valle
The hopping dynamics of two fermionic species with different effective masses in the one-dimensional Hubbard model driven by an external field is theoretically investigated. A mult…
Tamm-Hubbard surface states in the continuum
S. Longhi, G. Della Valle
In the framework of the Bose-Hubbard model, we show that two-particle surface bound states embedded in the continuum (BIC) can be sustained at the edge of a semi-infinite one-dimen…
Classical realization of two-site Fermi-Hubbard systems
S. Longhi, G. Della Valle, V. Foglietti
A classical wave optics realization of the two-site Hubbard model, describing the dynamics of interacting fermions in a double-well potential, is proposed based on light transport…
Classical simulation of the Hubbard-Holstein dynamics with optical waveguide lattices
Stefano Longhi, Giuseppe Della Valle
A classical analog simulator of the two-site Hubbard-Holstein model, describing the dynamics of two correlated electrons coupled with local phonons, is proposed based on light tran…
