Complex branches of a generalised Lambert function arising from --binomial coefficients
Per Åhag, Rafał Czyż, Per-Håkan Lundow
The -function, which solves the equation for , has a natural connection to the renowned Lambert function and also physical relevance through its…
Revising the universality class of the four-dimensional Ising model
P. H. Lundow, K. Markström
The aim of this paper is to determine the behavior of the specific heat of the 4-dimensional Ising model at the critical temperature, and via that determine if the Ising model and…
The Ising universality class in dimension three: corrections to scaling
P. H. Lundow, I. A. Campbell
Simulation data are analyzed for four 3D spin- Ising models: on the FCC lattice, the BCC lattice, the SC lattice and the Diamond lattice. The observables studied are the susce…
An extended scaling analysis of the S=1/2 Ising ferromagnet on the simple cubic lattice
I. A. Campbell, P. H. Lundow
It is often assumed that for treating numerical (or experimental) data on continuous transitions the formal analysis derived from the Renormalization Group Theory can only be appli…
The 1-vertex transfer matrix and accurate estimation of channel capacity
Shmuel Friedland, Per Hakan Lundow, Klas Markstrom
The notion of a 1-vertex transfer matrix for multi-dimensional codes is introduced. It is shown that the capacity of such codes, or the topological entropy, can be expressed as the…
