TL;DR: In this paper, an analytic theory for the static structure factor of the one-component classical plasma at strong couplings is presented, which combines the hard core model of Gillan for short-range correlations in the Coulomb fluid with a semi-empirical representation of intermediate-range correlation, through which the requirement of thermodynamic consistency on the ''compressibility'' and the known equation of state of the system are satisfied.
Abstract: An analytic theory is presented for the static structure factor of the one-component classical plasma at strong couplings. The theory combines the hard-core model of Gillan for short-range correlations in the Coulomb fluid with a semi-empirical representation of intermediate-range correlations, through which the requirement of thermodynamic consistency on the «compressibility» and the known equation of state of the system are satisfied. Excellent agreement is found with the available computer simulation data on the structure of the fluid. The approach becomes inapplicable at intermediate and weak couplings in which effects of penetration in the Coulomb hole of each particle become important.

TL;DR: In this paper, exact solutions of the IO(4, 2) covariant spinor field equation Γ a ϖξ ( η )/ ϖ η a = 0 are given which originate in Minkowski space two massive Dirac equations for a pair of conformal semispinors or for a doublet of coupled Dirac spinors both with canonical dimensions.

TL;DR: An analysis of the deep HEAO-2 survey has led to predict that QSOs up to mB=20 should emit Lx 2 Lo if radio-quiet, as compared with 07 Lo resulting for catalogued radio-loud; they contribute 20% of the X-ray background at 2 keV as discussed by the authors.

TL;DR: In this paper, the Hartree-Fock-Bogolubov theory with approximate projection of the particle number is applied to the rotational bands in nuclei and the results show that the speed with which the alignment occurs has an important effect on the appearance of anomalies at high angular momenta.
Abstract: Starting from the cranking model and applying the Hartree-Fock-Bogolubov theory with approximate projection of the particle number, one may give a satisfactory description of many properties of the rotational bands in nuclei. Calculations within the framework of this model show that the anomalies at high-spin states are caused by two effects: the Coriolis antipairing which reduces the energy gap with increasing angular momentum, on the one hand, and the alignment of the neutrons of positive parity along the axis of rotation, on the other hand. Moreover, the results show that the speed with which the alignment occurs has an important effect on the appearance of anomalies at high angular momenta.
