In this review article we describe spin-dependent transport in materials with spin–orbit
interaction of Rashba type. We mainly focus on semiconductor heterostructures, however we …

On a large class of lattices (such as the sawtooth chain, the kagome and the pyrochlore
lattices), the quantum Heisenberg and the repulsive Hubbard models may host a completely …

Exotic phases of matter can emerge from the interplay between strong electron interactions
and non-trivial topology. Materials that have non-dispersing bands in their electronic band …

Aharonov-Bohm (AB) caging, a special flat-band localization mechanism, has spurred great
interest in different areas of physics. AB caging can be harnessed to explore the rich and …

The induction of synthetic magnetic fields on lattice structures allows an effective control of
their localization and transport properties. In this Letter, we generate effective π magnetic …

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 …

Macroscopically degenerate flat bands (FB) in periodic lattices host compact localized states
which appear due to destructive interference and local symmetry. Interference provides a …

We experimentally demonstrate the photonic realization of a dispersionless flat band in a
quasi-one-dimensional photonic lattice fabricated by ultrafast laser inscription. In the nearest …

Lattices with dispersionless, or flat, energy bands have attracted substantial interest in part
due to the strong dependence of particle dynamics on interactions. Using superconducting …

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 …
