Choice of the uncritical manifold for dilute polymer solutions
Andrea Ostendorf, Johannes S. Hager
We discuss the dependence of the results of renormalized perturbation theory for dilute polymer solutions on the choice of the uncritical manifold where the perturbation series are…
Scaling of demixing curves and crossover from critical to tricritical behavior in polymer solutions
J. S. Hager, M. A. Anisimov, J. V. Sengers +1
In this paper we show that the virial expansion up to third order for the osmotic pressure of a dilute polymer solution, including first-order perturbative corrections to the viria…
2D Crystal Shapes, Droplet Condensation and Exponential Slowing Down in Simulations of First-Order Phase Transitions
Thomas Neuhaus, Johannes S. Hager
Multicanonical ensemble simulations for the simulation of first-order phase transitions suffer from exponential slowing down. Monte Carlo autocorrelation times diverge exponentiall…
Fluctuations of steps on crystal surfaces
W. Selke, F. Szalma, J. S. Hager
Fluctuations of isolated and pairs of ascending steps of monoatomic height are studied in the framework of SOS models, using mainly Monte Carlo techniques. Below the roughening tra…
Theta-point behavior of diluted polymer solutions: Can one observe the universal logarithmic corrections predicted by field theory?
Johannes Hager, Lothar Sch"afer
In recent large scale Monte-Carlo simulations of various models of Theta-point polymers in three dimensions Grassberger and Hegger found logarithmic corrections to mean field theor…
Relaxation of Surface Profiles by Evaporation Dynamics
Johannes Hager
We present simulations of the relaxation towards equilibrium of one dimensional steps and sinusoidal grooves imprinted on a surface below its roughening transition. We use a genera…
