Refined empirical stability criterion for nonlinear Schrödinger solitons under spatiotemporal forcing
(2011-08-25)
We investigate the dynamics of traveling oscillating solitons of the cubic nonlinear Schrödinger (NLS) equation under an external spatiotemporal forcing of the form f(x,t)=aexp[iK(t)x]. For the case of time-independent ...

Growth of nanocolumnar porous TiO2 thin films by magnetron sputtering using particle collimators
(Elsevier, 2018)
The selective incorporation of deposition species with preferential directionality is analyzed during the growth of TiO2 thin films by magnetron sputtering. Using wisely-designed collimators, tilted nanocolumnar morphol- ogies ...

Nonlinear localized modes in two-dimensional electrical lattices
(2013)
We report the observation of spontaneous localization of energy in two spatial dimensions in the context of nonlinear electrical lattices. Both stationary and moving self-localized modes were generated experimentally and ...

Soliton dynamics in optical fibers using the generalized traveling-wave method
(American Physical Society, 2016-04-21)
The generalized traveling wave method (GTWM) is applied to the nonlinear Schrödinger (NLS) equation with general perturbations in order to obtain the equations of motion for an ansatz with six collective coordinates, namely ...
