Photonics: Manipulating light with artificial fields Artificial gauge fields are a technique to engineer the potential landscape such that neutral particles mimic the dynamics of charged particles driven by external fields. Researchers in Israel and

We introduce topological phases in photonic space-time crystals, which have gaps in both momentum and frequency. We show that edge states waves refracted and reflected from spatial and temporal interfaces are governed by topological invariants.

We find superluminal solitons residing in the momentum gap of nonlinear photonic time-crystals and explore their faster-than-light pulse propagation in view of Einstein’s causality, the instantaneous response of time-varying permittivity, and signa

We study nonlinear effects in synthetic space photonic topological insulators. This nonlinearity is nonlocal in the synthetic dimensions. We study time-periodic solitons making a cyclotron-like motion in the synthetic space bulk.

We show that non-local nonlinearity can induce a preferred direction for the flow of random photonic wavepackets even in periodic structures. The phenomenon is nonlinear hence the directional transport depends on the optical power.

Synthetic-space topological insulators are topological systems with at least one spatial dimension replaced by a periodic arrangement of modes, in the form of a ladder of energy levels, cavity modes, or some other sequence of modes. Such systems can

We present topologically-protected propagation of unidirectional edge states at the interface between two dynamically-invariant systems with opposite effective magnetic field in synthetic dimensions.

Artificial gauge fields enable extending the control over dynamics of uncharged particles, by engineering the potential landscape such that the particles behave as if effective external fields are acting on them. Recent years have witnessed a growing
