    Research

    Granular matter

    Granular Gases are dilute systems of particles which collide inelastically. 
    Being rather simple by their nature, Granular Gases reveal very rich 
    behaviour: Cluster and vortex formation, characteristic shock waves 
    and non-Maxwellian velocity distribution may be mentioned as some 
    representative examples.

    Inelastic collisions

    The  theory of a collision of elastic particles was developed by H. Hertz in 1885. 
    We generalized Hertz's theory for dissipative collisions, using the simplest model 
    of viscoelastic particles. The generalized collision law allows to derive the main 
    characteristics of dissipative collisions - the restitution coefficient. It occurs, that 
    this quantity is not a material parameter, as was assumed previously, but rather 
    complicated function of elastic and dissipative material constants and of the 
    impact velocity at a collision.

    Rolling friction

    Up to our knowledge there was no first-principle theory which relates the 
    coefficient of rolling friction to material properties and a size of a rolling body 
    without any model parameters. We have developed a simple theory 
    of a rolling of a soft sphere on a hard plane.  We observe that rolling motion 
    may be treated as a "continuing collision". For a simple model of a soft plane 
    we developed a theory of a rolling of a hard cylinder on a soft plane.

    Complex fluids

    Polyelectrolytes and colloids

    Many important biological macromolecules, such as e.g. DNA,  are Polyelectrolytes.  Solutions of Polyelectrolytes and of Charged Colloidal paricles exhibit very interesting phase behavior: Phase transitions may be accompanied by a sudden change of  a gyration radius of a polymer chain,  of an average charge of a macromolecule, etc. We developed a theory of electrostatically driven  chain collapse in dilute polyelectrolyte solutions,  which occurs as a first-order phase transition (PRL 81, 1998).  Later this phase  transition has been detected in experiments (Mel'nikov  et al, JACS, 121  (1999) 1130).  We also developed a theory of phase transitions in colloidal solutions of particles with variable  surface charges.

    Hydrodynamics and brownian motion

    Particles in Complex Fluids, such as solutions of Polyelectrolyte or Colloids,  often carry a considerable charge. Hence, the local properties of the solvent, such as e.g. viscosity,  around the particles may be altered by the strong electric field. The other effect which is called the dielectric friction may also  significantly influence the Brownian motion of particles in Complex Fluids.  The molecular motion in these systems may be analyzed using the hydrodynamics of fluids with the internal degrees of freedom. For the case of polar solvents such hydrodynamic equations are called Hubbard-Onsager equations. Solving the these hydrodynamic 
    equations we obtain the generalization of Stokes-Einstein and Stokes-Einstein-Debye relations for translational and rotational Brownian motion.

    Phase transitions and critical behavior

    The critical behavior of simple fluids as well as of other fluids with a short-range interaction 
    potential corresponds to that of the Ising universality class. This follows from experiments, 
    computer simulations and theoretical reasonings.  For the  Coulombic Fluids however, it is still not completely clear to which universality class do these fluids belong. The most direct analysis of the critical properties of the system may be performed using the Landau-Ginzburg-Wilson (LGW) form of the system Hamiltonian. We develop a method which allows a rigorous mapping of the fluid Hamiltonian onto the effective field-theoretical LGW Hamiltonian,  which coefficients may be calculated analytically.  Using this approach we derive some relations between critical parameters, which have been confirmed in numerical experiments (Camp P.J., Patey G.N.,  J. Chem.Phys. 114 (2001) 399) and analyze the  coulombic criticality.

    Coulombic fluids

    Fluids  with long-range coulombic interactions, such as ionic solutions, plasma, etc. 
    are called coulombic fluids. The problem of critical behavior of  such fluids, i.e. of the 
    coulombic criticality, is still under discussion, since some the ionic fluids demonstrate 
    Ising criticality, while other - the classical one. Using the effective LGW Hamiltonian
    and nonperturbative RG approach, we show that very long crossover from the classical 
    to Ising critical behavior may be observed. For the simplest model of the coulombic fluid, 
    for the model of One Component Plasma we derived the equation of state (EOS) which is 
    very accurate for all values of plasma parameter, from the Debye-Huckel limit up to the 
    Wigner crystallization point.  To derive this EOS we propose the Restricted Random Phase 
    Approximation.

    Molecular Models of Diseases Kinetics

    It is generally acknowledged that transmittable spongiform encephaloathies diseases (TSE), such as scrapie, kuru and kind of Creutzfeld-Jacob disease are related to formation of misfolded fibril-like prion proteins.  Using a molecular model of the aggregation kinetics we describe the kinetics of the prion growth and derived the size distribution of the fibril aggregates.

    Brownian motion of biomolecules

    Biological functions of biomolecules in nature are intrinsically related to their mobility, i.e. to 
    the properties of the Brownian motion of these particles. Usually they are strongly  charged or have a large electrical dipolar moment.  The intensive electrostatic interactions between the charged and/or dipolar biomolecules or between the macromolecules and the polar solvent influence significantly their Brownian Motion .
