Exact cascading nonlinearity in quasi-phase-matched quadratic media [PDF]

open access: yes, 2014
The evolution of light pulses and beams in a quasi-phase-matched (QPM) quadratic medium is usually described by considering only the spatial harmonic of the QPM grating that minimizes the residual phase-mismatch.

Intermediary LEO propagation including higher order zonal harmonics

open access: yes, 2016
Two new intermediary orbits of the artificial satellite problem are proposed. The analytical solutions include higher order effects of the Geopotential, and are obtained by means of a torsion transformation applied to the quasi-Keplerian system resulting

Multipole solution of hydrodynamics and higher order harmonics [PDF]

open access: yes, 2014
The time evolution of the medium created in heavy ion collisions can be described by hydrodynamical models. After expansion and cooling, the hadrons are created in a freeze-out. Their distribution describes the final state of this medium.
