Matrix algorithm for solving Schroedinger equations with position-dependent mass or complex optical potentials
Johann Foerster, Alejandro Saenz, Ulli Wolff
We represent low dimensional quantum mechanical Hamiltonians by moderately sized finite matrices that reproduce the lowest O(10) boundstate energies and wave functions to machine p…
Finite size scaling and triviality of ϕ^4 theory on an antiperiodic torus
Matthijs Hogervorst, Ulli Wolff
Worm methods to simulate the Ising model in the Aizenman random current representation including a low noise estimator for the connected four point function are extended to allow f…
A factorization algorithm to compute Pfaffians
Jürgen Rubow, Ulli Wolff
We describe an explicit algorithm to factorize an even antisymmetric N^2 matrix into triangular and trivial factors. This allows for a straight forward computation of Pfaffians (in…
Performance of a worm algorithm in theory at finite quartic coupling
Tomasz Korzec, Ingmar Vierhaus, Ulli Wolff
Worm algorithms have been very successful with the simulation of sigma models with fixed length spins which result from scalar field theories in the limit of infinite quartic coupl…
