The critical Casimir force and its fluctuations in lattice spin models: exact and Monte Carlo results
Daniel Dantchev, Michael Krech
We present general arguments and construct a stress tensor operator for finite lattice spin models. The average value of this operator gives the Casimir force of the system close t…
Universality of the thermodynamic Casimir effect
Daniel Dantchev, Michael Krech, S. Dietrich
Recently a nonuniversal character of the leading spatial behavior of the thermodynamic Casimir force has been reported [X. S. Chen and V. Dohm, Phys. Rev. E {\bf 66}, 016102 (2002)…
Phase diagram of a model for 3He-4He mixtures in three dimensions
A. Maciolek, M. Krech, S. Dietrich
A lattice model of 3He - 4He mixtures which takes into account the continuous rotational symmetry O(2) of the superfluid degrees of freedom of 4He is studied in the molecular-field…
Dynamic surface critical behavior of isotropic Heisenberg ferromagnets: boundary conditions, renormalized field theory, and computer simulation results
H. W. Diehl, M. Krech, H. Karl
The dynamic critical behavior of isotropic Heisenberg ferromagnets with a planar free surface is investigated by means of field-theoretic renormalization group techniques and high-…
Dynamic surface scaling behavior of isotropic Heisenberg ferromagnets
M. Krech, H. Karl, H. W. Diehl
The effects of free surfaces on the dynamic critical behavior of isotropic Heisenberg ferromagnets are studied via phenomenological scaling theory, field-theoretic renormalization…
Surface scaling behavior of isotropic Heisenberg systems: Critical exponents, structure factor, and profiles
M. Krech
The surface scaling behavior of classical isotropic Heisenberg magnets is investigated by Monte - Carlo methods in d=3 dimensions for various values of the surface - to - bulk coup…
