The Mott-insulating phase of the two-dimensional (2D) Bose-Hubbard model is expected to
be characterized by a nonlocal brane parity order. Parity order captures the presence of …

We study the orbital susceptibility of multiband systems with a pair of Dirac points
interpolating between honeycomb and dice lattices. Despite having the same zero-field …

We report on the experimental realization of a uniform synthetic magnetic flux and the
observation of Aharonov-Bohm cages in photonic lattices. Considering a rhombic array of …

We propose an experimental setup for the observation of quasirelativistic massless
fermions. It is based on a T 3 optical lattice, realized by three pairs of counterpropagating …

In a flat Bloch band, the kinetic energy is quenched and single particles cannot propagate
since they are localized due to destructive interference. Whether this remains true in the …

We investigate topological characteristics of the photon-dressed band structure of the α-T 3
lattice on being driven by off-resonant circularly polarized radiation. We obtain exact …

We have laid out the results of a rigorous theoretical investigation into the response of
electron dressed states, ie, interacting Floquet states arising from the off-resonant coupling …

The electron states of gapped pseudospin-1 fermions of the α− T 3 lattice in the Coulomb
field of a charged impurity are studied. The free α− T 3 model has three dispersive bands …

We consider an α-T 3 lattice illuminated by intense circularly polarized radiation in the
terahertz regime. We present the quasienergy band structure, time-averaged energy …

A vison is an excitation of the Kitaev spin liquid which carries a Z 2 gauge flux. While
immobile in the pure Kitaev model, it becomes a dynamical degree of freedom in the …
