Dimensional reduction for optical beams with thermal nonlocal nonlinearity
Francesco Lorenzi, Luca Salasnich
Nonlocal optical nonlinearities arising from the thermorefractive effect provide a long-range material response determined by heat diffusion and absorption. In graded-index media,…

Variational approach to multimode nonlinear optical fibers
Francesco Lorenzi, Luca Salasnich
We analyze the spatiotemporal solitary waves of a graded-index multimode optical fiber with a parabolic transverse index profile. Using the nonpolynomial Schrödinger equation appro…

Two routes to the one-dimensional discrete nonpolynomial Schrödinger equation
G. Gligoric, A. Maluckov, L. Salasnich +2
The Bose-Einstein condensate (BEC), confined in a combination of the cigar-shaped trap and axial optical lattice, is studied in the framework of two models described by two version…
