We present the results of theoretical study of a new scenario of condensation phase transitions in ensemble of particles in ferrofluids. In this scenario the phase transition begins with the formation of linear chainlike clusters which collapse into dense globules when a number of particles in...

The free energy of the Ginzburg–Landau theory satisfies a nonlinear functional differential equation which is turned into a recursion relation. The latter is solved graphically order by order in the loop expansion to find all connected vacuum diagrams, and their corresponding weights. In this...

Using a model-potential introduced in a previous paper, properties of bismuth under shock loading at high pressure are studied here theoretically. In addition to the usual hydrodynamic behaviour for compact and porous material, our investigation extends to dynamical temperature determination, a...

We study an intrinsic curvature model defined on fixed-connectivity triangulated lattices enclosing a spherical core by using the canonical Monte Carlo simulation technique. We find that the model undergoes a discontinuous transition of shape transformation between the smooth state and a...

Polyelectrolytes are of great importance in different branches of chemistry and biology. DNA is a very good example of a polyelectrolyte of biological relevance. In this paper, we describe DNA solutions in the presence of multivalent salts and amphiphiles. After thermodynamic equilibrium is...

Clan concept has been introduced in multiparticle dynamics in order to interpret the wide occurrence of negative binomial (NB) regularity in n-charged particle multiplicity distributions (MDs) in various high energy collisions.

A short introduction on topological properties of (regular and random) geometrical sets is presented along with some recent results concerning the behaviour of the Euler–Poincaré characteristic with respect to the (Fortuin–Kasteleyn) random cluster measure.

Daily records of international crude oil prices are studied by means of a Zipf-type analysis. By using simple up-down information on price fluctuations, we have observed phase transitions between symmetric states, where occurrence of up and down fluctuations are almost equal, to anti-symmetric...
