Determination of the nearest-neighbor interaction in VO via fractal dimension analysis
Jacob Holder, Daniel Kazenwadel, Peter Nielaba +1
The Ising model is one of the simplest and most well-established concepts to simulate phase transformations in complex materials. However, its most central constant, the interactio…
Phase transitions in two-dimensional model colloids in a one-dimensional external potential
Florian Bürzle, Peter Nielaba
Two-dimensional melting transitions for model colloids in presence of a one-dimensional external periodic potential are investigated using Monte Carlo simulation and Finite Size Sc…
Phase Transitions of Soft Disks in External Periodic Potentials: A Monte Carlo Study
W. Strepp, S. Sengupta, P. Nielaba
The nature of freezing and melting transitions for a system of model colloids interacting by a DLVO potential in a spatially periodic external potential is studied using extensive…
Phase Transitions of Hard Disks in External Periodic Potentials: A Monte Carlo Study
W. Strepp, S. Sengupta, P. Nielaba
The nature of freezing and melting transitions for a system of hard disks in a spatially periodic external potential is studied using extensive Monte Carlo simulations. Detailed fi…
Path integral Monte Carlo simulations of silicates
Chr. Rickwardt, P. Nielaba, M. H. Müser +1
We investigate the thermal expansion of crystalline SiO in the -- cristobalite and the -quartz structure with path integral Monte Carlo (PIMC) techniques. This simulation…
Defect fugacity, Spinwave Stiffness and T_c of the 2-d Planar Rotor Model
S. Sengupta, P. Nielaba, K. Binder
We obtain precise values for the fugacities of vortices in the 2-d planar rotor model from Monte Carlo simulations in the sector with {\em no} vortices. The bare spinwave stiffness…
