Variational method for finding periodic orbits in a general flow
Yueheng Lan, Predrag Cvitanovic
A variational principle for determining unstable periodic orbits of flows as well as unstable spatio-temporally periodic solutions of extended systems is proposed and implemented.…
Turbulent fields and their recurrences
Predrag Cvitanovic, Yueheng Lan
We introduce a new variational method for finding periodic orbits of flows and spatio-temporally periodic solutions of classical field theories, a generalization of the Newton meth…
A Perturbative Analysis of Modulated Amplitude Waves in Bose-Einstein Condensates
Mason A. Porter, Predrag Cvitanovic'
We apply Lindstedt's method and multiple scale perturbation theory to analyze spatio-temporal structures in nonlinear Schrödinger equations and thereby study the dynamics of quasi-…
Modulated Amplitude Waves in Bose-Einstein Condensates
Mason A. Porter, Predrag Cvitanovic
We analyze spatio-temporal structures in the Gross-Pitaevskii equation to study the dynamics of quasi-one-dimensional Bose-Einstein condensates (BECs) with mean-field interactions.…
