The role of super-spreaders in modeling of SARS-CoV-2
F Rousse, M Carlsson, M Ogren +1
In stochastic modeling of infectious diseases, it has been established that variations in infectivity affect the probability of a major outbreak, but not the shape of the curves du…
Stationary states of Bose-Einstein condensed atoms rotating in an asymmetric ring potential
M. Ögren, Giannis Drougakis, Giorgos Vasilakis +2
We consider a Bose-Einstein condensate, which is confined in a very tight toroidal/annular trap, in the presence of a potential, which breaks the axial symmetry of the Hamiltonian.…
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…
Matter waves in atomic-molecular condensates with Feshbach resonance management
F Kh Abdullaev, M Ogren, J S Yuldashev
The dynamics of matter waves in the atomic to molecular condensate transition with a time-modulated atomic scattering length is investigated. Both the cases of rapid and slow modul…
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…
