AbstractThe static properties of nematic liquid crystals are summarized. The mean field potential emerging from the static distribution function has been used to the hydrodynamic theory. Rotational viscosity coefficients have been investigated. The Parodi relation has been shown to be completely satisfied. Static and hydrodynamic properties have been predicted on the basis of one intermolecular potential

Surface tension of quark–gluon plasma (QGP) evolution with one-loop correction in the mean-field potential is studied. First, with the correction, the stable QGP droplet size decreases. Then, the value of surface tension is found to be improved and it approaches to the lattice value of surface tension [Formula: see text]. Moreover, the ratio of the surface tension to the cube of the critical temperature is found to increase the value in comparison to earlier studies without correction factor [R. Ramanathan, K. K. Gupta, A. K. Jha and S. S. Singh, Pram. J. Phys. 68, 757 (2007)].

Model Approach

In this paper, the ratio of the mass coefficients for the γ-vibrational and rotational motion for the well deformed axially symmetric nuclei is calculated. Calculations are performed based on the Cranking model approach. The results obtained show that the microscopic model based on the Woods–Saxon nuclear mean field potential and the pairing forces with a constant strength coefficient qualitatively explain the existing experimental data on the ratio of the mass coefficients. The important role of the blocking effect in the calculation of the mass coefficients is demonstrated.

Shell Energy

We have performed calculations of the nuclear potential energies in a 5-dimensional space of deformation parameters including α20, α22, α40, α42 and α44 multipole deformations by using the macroscopic-microscopic method. The energy expression contains the macroscopic term (in our case in the form of the Lublin Strasbourg Drop – LSD) and the microscopic terms of the Strutinsky shell energy and projected BCS pairing energy. The single-particle energies are obtained from the classical mean-field potential as well as from the correspondig Dirac relativistic realisation of the mean-field, both parametrised with the help of the deformed Woods-Saxon forms. Our resuls are compared to the selfconsistent Hartree Fock Bogolubov method with the D1S Gogny force.
