Photonic quantum technologies represent a promising platform for several applications,
ranging from long-distance communications to the simulation of complex phenomena …

The physics of a photonic structure is commonly described in terms of its apparent geometric
dimensionality. On the other hand, with the concept of synthetic dimension, it is in fact …

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 …

The advent of visible-infrared laser pulses carrying a substantial fraction of their energy in a
single field oscillation cycle has opened a new era in the experimental investigation of …

We study the generation of high-harmonic radiation by Bloch electrons in a model
transparent solid driven by a strong midinfrared laser field. We solve the single-electron time …

Over the last few years arrays of evanescently coupled waveguides have been brought into
focus as a particular representation of functionalized optical materials, in which the …

Bloch oscillations in complex lattices with PT symmetry are theoretically investigated with
specific reference to optical Bloch oscillations in photonic lattices with gain or loss regions …

We review both theoretical and experimental advances in the recently emerged field of
modulated photonic lattices. These artificial periodic dielectric structures provide a powerful …

Non-Bloch-band theory describes bulk energy spectra and topological invariants in non-
Hermitian crystals with open boundaries, where the bulk eigenstates are squeezed toward …

Microcavity polaritons are mixed light–matter quasiparticles with extraordinary nonlinear
properties, which can be easily accessed in photoluminescence experiments. Thanks to the …
