Equilibrium thermodynamical characteristics of ferrosmectics are estimated under conditions when both magnetic and steric interparticle interactions are taken into account. Deformation and condensation phase transitions in ferrosmectics are studied.

We demonstrate that there is an intimate relationship between the magnetic properties of Derrida’s random energy model (REM) of spin glasses and the problem of joint source–channel coding in Information Theory. In particular, typical patterns of erroneously decoded messages in the coding...

The spin-1/2 Ising model on a square lattice, with fluctuating bond interactions between nearest neighbors and in the presence of a random magnetic field, is investigated within the framework of the effective field theory based on the use of the differential operator relation. The random field...
