Dynamical representations of constrained multicomponent nonlinear Schrödinger equations in arbitrary dimensions
M Gulliksson, M Ogren
We present new approaches for solving constrained multicomponent nonlinear Schrödinger equations in arbitrary dimensions. The idea is to introduce an artificial time and solve an e…
A numerical damped oscillator approach to constrained Schrödinger equations
M. Ogren, M. Gulliksson
This article explains and illustrates the use of a set of coupled dynamical equations, second order in a fictitious time, which converges to solutions of stationary Schrödinger equ…
Numerical simulations of NMR relaxation in chalk using local Robin boundary conditions
M. Ogren, D. Jha, S. Dobberschutz +5
The interpretation of nuclear magnetic resonance (NMR) data is of interest in a number of fields. In Ögren [Eur. Phys. J. B (2014) 87: 255] local boundary conditions for random wal…
Damped second order flow applied to image denoising
George Baravdish, Olof Svensson, Mårten Gulliksson +1
In this paper, we introduce a new image denoising model: the damped flow (DF), which is a second order nonlinear evolution equation associated with a class of energy functionals of…
