Tunable anisotropic magnetism in trapped two-component Bose gases

, 2011
We theoretically address magnetic ordering at zero and finite temperature in both homogeneous and trapped Bose-Bose mixtures in optical lattices. By using Bosonic Dynamical Mean-Field Theory, we obtain the phase diagram of the homogeneous two-component ...

Spin-1 Bose-Hubbard model with two- and three-body interactions

, 2018
We investigated the ground state of spin-1 bosons interacting under local two- and three-body interactions in one dimension by means of the density matrix renormalization group method.

Dirac Point and Edge States in a Microwave Realization of Tight-Binding Graphene-like Structures

, 2010
We present a microwave realization of finite tight-binding graphene-like structures. The structures are realized using discs with a high index of refraction.

Spin-orbit coupling and optical spin Hall effect in photonic graphene

, 2014
We study the spin-orbit coupling induced by the splitting between TE and TM optical modes in a photonic honeycomb lattice. Using a tight-binding approach, we calculate analytically the band structure.

Phase diagram of spin-1/2 bosons in one-dimensional optical lattice

, 2010
Systems of two coupled bosonic species are studied using Mean Field Theory and Quantum Monte Carlo. The phase diagram is characterized both based on the mobility of the particles (Mott insulating or superfluid) and whether or not the system is magnetic ...

Phase diagram of the Bose Kondo-Hubbard model

, 2011
We study a bosonic version of the Kondo lattice model with an on-site repulsion in the conduction band, implemented with alkali atoms in two bands of an optical lattice.

Quantum relaxation and metastability of lattice bosons with cavity-induced long-range interactions

, 2018
The coupling of cold atoms to the radiation field within a high-finesse optical resonator, an optical cavity, induces long-range interactions which can compete with an underlying optical lattice.

Spiral spin textures of bosonic Mott insulator with SU(3) spin-orbit coupling

, 2014
We study the Mott phase of three-component bosons, with one particle per site, in an optical lattice by mapping it onto an SU(3) spin model. In the simplest case of full SU(3) symmetry, one obtains a ferromagnetic Heisenberg model.
