Critical Adsorption in Systems with Weak Surface Field: The Renormalization-Group Approach
A. Ciach, U. Ritschel
We study the surface critical behavior of semi-infinite systems belonging to the bulk universality class of the Ising model. Special attention is paid to the local behavior of expe…
Comment on ``Generalized Dynamic Scaling for Critical Relaxation" [Phys. Rev. Lett. 77, 679 (1996), cond-mat/9607013]
U. Ritschel, P. Czerner
We point out that in nonequilibrium relaxational processes the magnetic field of the initial state (instead of the initial magnetization) has to be considered as the additional sca…
Near-Surface Long-Range Order at the Ordinary Transition: Scaling Analysis and Monte Carlo Results
P. Czerner, U. Ritschel
Motivated by recent experimental activities on surface critical phenomena, we present a detailed theoretical study of the near-surface behavior of the local order parameter m(z) in…
Microscopic Non-Universality versus Macroscopic Universality in Algorithms for Critical Dynamics
U. Ritschel, P. Czerner
We study relaxation processes in spin systems near criticality after a quench from a high-temperature initial state. Special attention is paid to the stage where universal behavior…
Near-Surface Long-Range Order at the Ordinary Transition
Uwe Ritschel, Peter Czerner
We study the spatial dependence of the order parameter near surfaces belonging to the universality class of the ordinary transition. Special attention is paid to the influence of a…
