Pinned solitons are a special class of nonlinear solutions created by supersonically moving object in fluid. They move with the same velocity as and thereby remain pinned to object. A well known hydrodynamical phenomenon, they have been shown exist numerical simulation studies but date not observed experimentally plasma. In this paper we report first experimental excitation dusty (complex) plas...

Spatial self-imaging, consisting of the periodic replication optical transverse beam profile along propagation direction, can be achieved in guided wave systems when all excited modes interfere phase. We exploited material defects photoluminescence for directly visualizing self-imaging a few-mode, nominal singlemode SMF-28 fiber. Visible luminescence was by intense femtosecond infrared pulses v...

Statistical spin dynamics plays a key role to understand the working principle for novel optical Ising machines. Here we propose gauge transformations spatial photonic machine, where single phase modulator simultaneously encodes configurations and programs interaction strengths. Thanks transformation, experimentally evaluate diagram of high-dimensional spin-glass equilibrium system with $100$ f...

In the last few decades, topological phase1–11 has emerged as a new classification of matter states beyond Ginzburg–Landau symmetry-breaking paradigm. The underlying global invariant is usually well characterized by integers, such Chern numbers or winding numbers—the Abelian charges12–15. Very recently, researchers proposed notion non-Abelian charges16–19, which possess non-commutative and frui...

We reveal unconventional edge states in a one-dimensional Stub lattice of coupled waveguides with staggered hoppings. The appear for the same values hoppings as topological Su-Schrieffer-Heeger model. They have different energies depending on termination and present remarkable robustness against certain types disorder. evidence experimentally phase transition at which these appear, opening door...
