Automatic code generator for higher order integrators
Asif Mushtaq, Kåre Olaussen
Some explicit algorithms for higher order symplectic integration of a large class of Hamilton's equations have recently been discussed by Mushtaq \emph{et. al}. Here we present a P…
Quantum loop expansion to high orders, extended Borel summation, and comparison with exact results
Amna Noreen, Kåre Olaussen
We compare predictions of the quantum loop expansion to (essentially) infinite orders with (essentially) exact results in a simple quantum mechanical model.We find that there are e…
High precision series solution of differential equations: Ordinary and regular singular point of second order ODEs
Amna Noreen, Kåre Olaussen
A subroutine for very-high-precision numerical solution of a class of ordinary differential equations is provided. For given evaluation point and equation parameters the memory req…
Very-high-precision solutions of a class of Schr{ö}dinger equations
Asif Mushtaq, Amna Noreen, Kåre Olaussen +1
We investigate a method to solve a class of Schr{ö}dinger equation eigenvalue problems numerically to very high precision (from thousands to a million of decimals). The memory…
Symmetry and Mass Degeneration in Multi-Higgs-Doublet Models
K. Olaussen, P. Osland, M. Aa. Solberg
We investigate possible symmetry properties of the scalar sector of Multi-Higgs-Doublet Models, and, to some extent, the generalization of such models to gauge groups other than $S…
Resolution of an apparent inconsistency in the electromagnetic Casimir effect
H. Alnes, K. Olaussen, F. Ravndal +1
The vacuum expectation value of the electromagnetic energy-momentum tensor between two parallel plates in spacetime dimensions D > 4 is calculated in the axial gauge. While the pre…
