Topologically protected midgap states in complex photonic lattices.
One of the principal goals in the design of photonic crystals is the engineering of band gaps and defect states. Here I describe the formation of topologically protected localized midgap states in systems with spatially distributed gain and loss. These states can be selectively amplified, which finds applications in the beam dynamics along a photonic lattice and in the lasing of quasi-one-dimen...
متن کاملObservation of Bloch oscillations in complex PT-symmetric photonic lattices
Light propagation in periodic environments is often associated with a number of interesting and potentially useful processes. If a crystalline optical potential is also linearly ramped, light can undergo periodic Bloch oscillations, a direct outcome of localized Wannier-Stark states and their equidistant eigenvalue spectrum. Even though these effects have been extensively explored in conservati...
متن کاملEffects of Long-Range Coupling on Aggregation
It has been recently shown that screening, due to free charges, strongly diversifies the pattern that grow in electrostatic fields [1, 2] (see also [3]). By solving the Poisson equation, a transition from dense to multibranched growth has been found which depends on the potentials and ' at two boundaries, the distance between them, L — l, and an inverse screening length 1. In this note we il...
متن کاملLong-range neural coupling through synchronization with attention.
In a crowded visual scene, we typically employ attention to select stimuli that are behaviorally relevant. Two likely cortical sources of top-down attentional feedback to cortical visual areas are the prefrontal (PFC) and posterior parietal (PPC) cortices. Recent neurophysiological studies show that areas in PFC and PPC process signals about the locus of attention earlier than in extrastriate v...
متن کاملLong-Range Electron Transport Donor-Acceptor in Nonlinear Lattices
We study here several simple models of the electron transfer (ET) in a one-dimensional nonlinear lattice between a donor and an acceptor and propose a new fast mechanism of electron surfing on soliton-like excitations along the lattice. The nonlinear lattice is modeled as a classical one-dimensional Morse chain and the dynamics of the electrons are considered in the tight-binding approximation....
