Effects of turbulent transfer on the critical behaviour
Effects of turbulent transfer critical behaviour
2010/12/28
Critical behaviour of two systems, subjected to the turbulent mixing,is studied by means of the field theoretic renormalization group. The first system,described by the equilibrium model A, correspond...
Interaction anisotropy and random impurities effects on the critical behaviour of ferromagnets
Interaction anisotropy random impurities effects critical behaviour of ferromagnets
2010/11/23
The theory of phase transitions is based on the consideration of "idealized" models, such as the Ising model: a system of magnetic moments living on a cubic lattice and having only two accessible stat...
Competition, coexistence, and critical behaviour in a lattice tumor-growth model
Competition coexistence critical behaviour lattice tumor-growth model

In the present paper we study a lattice tumor-growth model. Monte Carlo simulations for $d=$1, 2, and 3 show that when nutrients are easily available, normal and tumor cells coexist. However, when the...
