Effective and asymptotic criticality of structurally disordered magnets
Maxym Dudka, Mariana Krasnytska, Juan J. Ruiz-Lorenzo +1
Changes in magnetic critical behaviour of quenched structurally-disordered magnets are usually exemplified in experiments and in MC simulations by diluted systems consisting of mag…

This paper continues our previous study on spreading processes in inhomogeneous populations consisting of susceptible and immune individuals [V. Blavatska, Yu. Holovatch, Physica A…
Critical Behavior of the Three-Dimensional Random Anisotropy Heisenberg Model
J. J. Ruiz-Lorenzo, M. Dudka, Yu. Holovatch
We have studied the critical properties of the three-dimensional random anisotropy Heisenberg model by means of numerical simulations using the Parallel Tempering method. We have s…
Spreading processes in "post-epidemic" environments
V. Blavatska, Yu. Holovatch
We analyze infection spreading processes in a system where only a fraction of individuals can be affected by disease, while remaining individuals are immune. Such a pictu…

The critical dynamics of model C in the presence of disorder is considered. It is known that in the asymptotics a conserved secondary density decouples from the nonconserved order…
