Localized States Emerging from Singular and Nonsingular Flat Bands in a Frustrated Fractal?Like Photonic Lattice
نویسندگان
چکیده
Singular and nonsingular flat bands in a Sierpinski fractal-like photonic lattice are reported. It is demonstrated that the lowest two bands, being isolated degenerate due to geometrical frustration, thus can be spanned by complete set of compact localized states. These states experimentally proven propagate diffractionless lattice. The results reveal interplay between single lattice, pave way spin liquid ground

Observation of a Localized Flat-Band State in a Photonic Lieb Lattice.
We demonstrate the first experimental realization of a dispersionless state, in a photonic Lieb lattice formed by an array of optical waveguides. This engineered lattice supports three energy bands, including a perfectly flat middle band with an infinite effective mass. We analyze, both experimentally and theoretically, the evolution of well-prepared flat-band states, and show their remarkable ...
متن کاملFlat bands and Wigner crystallization in the honeycomb optical lattice.
We study the ground states of cold atoms in the tight-binding bands built from p orbitals on a two dimensional honeycomb optical lattice. The band structure includes two completely flat bands. Exact many-body ground states with on-site repulsion can be found at low particle densities, for both fermions and bosons. We find crystalline order at n=1/6 with a sqrt[3] x sqrt[3] structure breaking a ...
متن کاملFlat photonic surface bands pinned between Dirac points.
We point out that 2D photonic crystals (PhCs) can support surface bands that are pinned to Dirac points. These bands can be made very flat by optimizing the parameters of the system. Surface modes are found at the interface of two different cladding materials: one is a PhC with Dirac linear dispersion for the TE mode, and the other is a PhC that has a broad TE gap at the Dirac frequency.
متن کاملSelf-localized states in photonic topological insulators.
We propose solitons in a photonic topological insulator: self-localized wave packets forming topological edge states residing in the bulk of a nonlinear photonic topological insulator. These self-forming entities exhibit, despite being in the bulk, the property of unidirectional transport, similar to the transport their linear counterparts display on the edge of a topological insulator. In the ...
