Width of Rough Interfaces on Asymmetric Lattices
K. Pinn
I present a calculation of the interfacial width within the capillary wave (Gaussian) approximation. The calculation is done on rectangular lattices of size L_1 times L_2, with per…
A Chaotic Cousin Of Conway's Recursive Sequence
K. Pinn
I study the recurrence D(n)= D(D(n-1))+D(n-1-D(n-2)), D(1)=D(2)=1. Its definition has some similarity to that of Conway's sequence defined through a(n)= a(a(n-1))+a(n-a(n-1)), a(1)…
Monte Carlo Algorithms For the Fully Frustrated XY Model
S. Grosse Pawig, K. Pinn
We investigate local update algorithms for the fully frustrated XY model on a square lattice. In addition to the standard updating procedures like the Metropolis or heat bath algor…
3D Ising Model with Improved Scaling Behaviour
M. Hasenbusch, K. Pinn, S. Vinti
We present results from the simulation of a two-coupling spin-1 model with states 0,+1,-1 and nearest neighbour interaction. By a suitable choice of couplings we are able to drasti…
The Solid-on-Solid Surface Width Around the Roughening Transition
H. G. Evertz, M. Hasenbusch, M. Marcu +1
We investigate the surface width of solid-on-solid surfaces in the vicinity of the roughening temperature . Above , is expected to diverge with the system size…
