A topological charge selection rule for phase singularities
M. Zacares, M. A. Garcia-March, J. Vijande +2
We present an study of the dynamics and decay pattern of phase singularities due to the action of a system with a discrete rotational symmetry of finite order. A topological charge…
Symmetry, winding number and topological charge of vortex solitons in discrete-symmetry media
Miguel-Ángel García-March, Albert Ferrando, Mario Zacarés +2
We determine the functional behavior near the discrete rotational symmetry axis of discrete vortices of the nonlinear Schrödinger equation. We show that these solutions present a c…
Supersolid behavior of nonlinear light
Albert Ferrando, Miguel Ángel García-March, Mario Zacarés
We present a formal demonstration that light can simultaneously exhibit a superfluid behavior and spatial long-range order when propagating in a photonic crystal with self-focussin…
Angular Pseudomomentum Theory for the Generalized Nonlinear Schrödinger Equation in Discrete Rotational Symmetry Media
M. -Á. García-March, A. Ferrando, M. Zacarés +2
We develop a complete mathematical theory for the symmetrical solutions of the generalized nonlinear Schrödinger equation based on the new concept of angular pseudomomentum. We con…
