On removing orders from amplitude equations
David Juhasz, Per Kristen Jakobsen
In this paper, we introduce a modified version of the renormalization group (RG) method and test its numerical accuracy. It has been tested on numerous scalar ODEs and systems of O…
On the numerical accuracy of the method of multiple scales for nonlinear dispersive wave equations
David Juhasz, Per Kristen Jakobsen
In this paper we study dispersive wave equation using the method of multiple scales (MMS) and perform several numerical tests to investigate its accuracy. The key feature of our MM…
Constructing a partially transparent computational boundary for UPPE using leaky modes
David Juhasz, Per Kristen Jakobsen
In this paper we introduce a method for creating a transparent computational boundary for the simulation of unidirectional propagation of optical beams and pulses using leaky modes…
Convergence and completeness for square-well Stark resonant state expansions
David Juhasz, Miroslav Kolesik, Per K. Jakobsen
In this paper we investigate the completeness of the Stark resonant eigenstates for a particle in a square-well potential. We find that the resonant state expansions for target fun…
