Magnetization Profile in the d=2 Semi-Infinite Ising Model and Crossover between Ordinary and Normal Transition
P. Czerner, U. Ritschel
We theoretically investigate the spatial dependence of the order parameter of the two-dimensional semi-infinite Ising model with a free surface at or above the bulk critical temper…
Universal Short-Time Dynamics in the Kosterlitz-Thouless Phase
P. Czerner, U. Ritschel
We study the short-time dynamics of systems that develop ``quasi long-range order'' after a quench to the Kosterlitz-Thouless phase. With the working hypothesis that the ``universa…
Casimir Forces between Spherical Particles in a Critical Fluid and Conformal Invariance
E. Eisenriegler, U. Ritschel
Mesoscopic particles immersed in a critical fluid experience long-range Casimir forces due to critical fluctuations. Using field theoretical methods, we investigate the Casimir int…
Universal Short-Time Behavior in Critical Dynamics near Surfaces
U. Ritschel, P. Czerner
We study the time evolution of classical spin systems with purely relaxational dynamics, quenched from T >> T_c to the critical point, in the semi-infinite geometry. Shortly after…
Long-time traces of the initial condition in relaxation phenomena near criticality
U. Ritschel, H. W. Diehl
The time evolution of systems relaxing towards thermal equilibrium is examined near the critical temperature , with special attention paid to the role of the initial value $m_…
