Hydrodynamic Calculations

The validity of hydrodynamic approximations for non-equilibrium plasmas is examined, with emphasis on applications to laser-driven fusion pellets. Typical density–temperature trajectories of such pellets, as predicted by hydrodynamic calculations in the published literature, are shown to lie sometimes outside the region of validity of hydrodynamic theory, which is an unsatisfactory situation. In view of this, we discuss certain criteria which can be easily used to test the self- consistent validity of any hydrodynamic result. Finally, it is noted that in the low-density, low-temperature plasma region, hydrodynamics initially breaks down because of a breakdown in conventional microscopic linear response theory. A modified microscopic theory is proposed which continues to be valid in this region. This may correspondingly extend the validity of hydrodynamics to plasmas of somewhat lower temperatures and densities.

Self Consistent Field

The correlative unsymmetrized self-consistent field method developed in preceding works is used to study the structural, dynamical, and thermodynamic properties of the (110) and (111) faces of the anharmonic BCC crystal. The character of the lattice relaxation near the (110) surface is similar to that near the (001) face investigated in Part I. There is strong anisotropy in the atomic vibrations near the (110) surface and in its thermodynamic functions. Near the (111) face the lattice relaxation decreases gradually, with oscillations occurring in the interplanar distances. It should be emphasized that such results are obtained when the nearest-neighbour interactions are taken into account. Unlike the (001) face, the surface tensions of the faces considered are negative. The effect of the long-range interactions are studied. In the preceding papers1–7 the correlative unsymmetrized self-consistent field method (CUSF) has been developed to investigate the structural, dynamical, and thermodynamic surface properties of anharharmonic crystals. In the first part of this work7 (to be referred to as I), the (001) faces of BCC crystals have been studied taking into account the nearest-neighbour interactions. Here we shall calculate the properties of other singular surfaces of such crystals.

We briefly review the observable signature and computational efforts of growth and merging phenomena of astrophysical black holes. We examine the meaning, and assess the validity of such properties within theoretical framework of the long-standing phenomenological model of black holes (PMBHs), being a peculiar repercussion of general relativity. We provide a discussion of some key objectives with the analysis aimed at clarifying the current situation of the subject. It is argued that such exotic hypothetical behaviors seem nowhere near true if one applies the PMBH. Refining our conviction that a complete, self-consistent gravitation theory will smear out singularities at huge energies, and give the solution known deep within the BH, we employ the microscopic theory of black hole (MTBH), which has explored the most important novel aspects expected from considerable change of properties of space-time continuum at spontaneous breaking of gravitation gauge symmetry far above nuclear density. It may shed further light upon the growth and merging phenomena of astrophysical BHs.
