The effect of a local anisotropy of random orientation on a ferromagnetic phase transition is studied. To this end, a model of a random anisotropy magnet is analysed by means of a field theoretical renormalization ...

Among the quantum liquids, the hydrogens cover an interesting position between liquid helium, where quantum exchange gives rise to the macroscopic phenomenon of superfluidity, and neon, where quantum effects are relatively ...

Based on the generalized kinetic equation for single and pair correlation distribution functions, analytical expressions for dynamic coefficients of shear and bulk viscosity and corresponding elastic modulus are ...

This book was published in 1997 in the series “Proceedings of the International School of Physics “Enrico Fermi” and contains the lectures and contributions presented at the CXXXIV Course of Enrico Fermi School held ...

In the present paper, the pressure-temperature phase diagram of a generalized Hubbard model with correlated hopping in a paramagnetic state at half-filling is determined by means of a generalized mean-field approximation in ...

The analytical solution of the Mean Spherical Approximation for a quite general class of interactions is always a function of a reduced set of scaling matrices Γχ. We extend this result to systems with multipolar ...

We present a theoretical study of the possibility of optical singularity birth in a wave front of a laser beam passing through a homeotropically aligned nematic liquid crystal (LC) cell. At intensities below some threshold ...

Short–wavelength asymptotics of time correlation functions (TCF) of simple classical fluids is considered in the framework of short time expansion. The explicit expressions for zeroth time moments up to the 8-th order ...

We present a statistical theory for diffusion-reaction processes of gaseous mixture in the system “metal-adsorbate-gas”. The theory is based on an equal consideration of electron-electron, electron-atom and atom-atom ...

In the limit of infinite spatial dimensions, a thermodynamically consistent theory, which is valid for arbitrary value of the Coulombic interaction ( U < ∞ ), is built for the Hubbard model when the total auxiliary ...
