We design tailored artificial optical gauge fields with ordinary dielectric birefringent materials. Using this method, we realize a wide range of phenomena: Quantum Hall effect, Haldane Topological-Insulators, Rashba effect and more.
We observe non-diffracting beam channels propagating in liquid soap membranes and study this phenomenon experimentally. The channel's width is determined by the power of the beam and the thickness of the membrane.
We show that, counterintuitive, it is possible to control the properties of photonic topological insulators by tailoring defects. In the extreme case, a lattice of defects inside a topological insulator creates a totally new topological insulator.
We propose a new class of photonic topological insulators, for which we use synthetic dimensions to induce topologically-protected photonic propagation in the bulk of the lattice instead of around the edge.
We show that non-Hermitian bipartite optical lattices display a spontaneous phase transition from a regime of entirely real spectrum to a complex one. This work broadens the scope of non-Hermitian optics beyond PT-symmetry.
The general relativity effect of frame-dragging: the precession of test particles in the spacetime surrounding spinning masses, is demonstrated by solitons rotating the space around them via nonlocal nonlinearities, transferring angular momentum to probe beams.
We introduce non-diffracting accelerating beams propagating on spherical surfaces. We find close form-solutions to the wave equation, and demonstrate their non-geodesic propagation dynamics in experiments.
We present topological photonics in curved space. We use 1D waveguide lattices on curved surfaces, and show that the curvature of the surface induces topological phase transfer dynamics, Thouless pumping, localization and delocalization of waves.
We present the first topological laser: topologically-protected lasing in photonic honeycomb lattices. We show that the lasing modes are unidirectional and robust to defects.
We show that it is possible to have topological transport in photonic quasicrytals, and therefore this lattices have one-way extended edgestates that are topologically protected against backscattering as they pass through defects or around corners.
We review the recent progress on the first experimental demonstration of photonic topological insulators, along with a variety of new ideas associated with it.
We show that a Lieb photonic lattice of helical waveguides (without any external field) has one-way edge states that are topologically protected against backscattering as they pass through defects or around corners.
We present electromagnetic three-dimensional spatially accelerating waves whose transverse profiles propagate along semicircular trajectories while approximately preserving their shape. Our results allow the generation of accelerating waves with novel transverse distributions, broadening their application even further.
We study various methods for computing the one-loop correction to the energy of classical solutions to type IIA string theory in AdS4 × CP3. This involves computing the spectrum of fluctuations and then adding up the fluctuation frequencies. We focus on two classical solutions with support in CP3: a rotating point-particle and a circular spinning string with two angular momenta equal to J. For...
