In this note we give a new upper bound for the Laplacian eigenvalues of an unweighted graph. Let $G$ be a simple graph on $n$ vertices. Let $d_{m}(G)$ and $\lambda_{m+1}(G)$ be the $m$-th smallest degree of $G$ and the $m+1$-th smallest... more

We present self-accelerating self-trapped beams in self-focusing and self-defocusing Kerr and saturable media. Such beams are stable under self-defocusing and weak self-focusing, whereas for strong self focusing they off-shoot solitons... more
ABSTRACT In 1958, a revolutionary paper by Aharonov and Bohm predicted a phase difference between two parts of an electron wavefunction even when being confined to a regime with no EM field. The Aharonov-Bohm effect was groundbreaking:... more

ABSTRACT We present a new approach for optimizing a 3D non-paraxial volume for multiphoton florescence microscopy. Our optimized solutions demonstrate volume reduction of up to 6.5, compared to the best current design for three-photon... more
