Superfluidity of Nuclear Matter
Physical Review Letters, 1959A criterion for the superfluidity of infinite nuclear matter was given in the form of a variational principle by Cooper, Mills, and Sessler, (Phys. Rev. 114, 1377 (1959)). Computations are reported which are an iraprovement over those in CMS in three respects: the effective mass approxirmtion was removed, more realistic two-body potentials were ...

Combustion of nuclear matter into strange matter
Physical Review D, 1994We study the properties of the combustion of pure neutron matter into strange matter in the framework of relativistic hydrodynamical theory of combustion. Because of the uncertainties in the actual properties of neutron matter, we employ the free neutron, Bethe-Johnson, Lattimer-Ravenhall, and Walecka equations of state and for strange matter we adopt ...

Physical Review Letters, 1960
Equations for explicit Hartree states of energy lower than that of conventional ground states for noninteracting Fermi gases are given for Fermi gases with attractive interactions. One-dimensional and three-dimensional cases are treated. Large static density waves are shown to exist in such Fermi gases, and the binding energy is derived therefrom.

Physical Review C, 1992
We use the toy model of baryon bag formation to study the changes in the structure of a nucleon when it is placed in nuclear matter. Several interesting qualitative results have been found. We find that ${\mathit{M}}^{\mathrm{*}}$, the nucleon mass in nuclear matter, does not scale with ${\mathit{F}}_{\mathrm{\ensuremath{\pi}}}^{\mathrm{*}}$, the ...

Physical Review, 1961
The methods of quantum statistics previously developed 0ry the author are applied to the determination of properties of the ground state of nuclear matter. An expansion in powers of the pair-function of quantum statistics is made and expressions are derlved for the momentum distribution, pair-correlation function, binding energy, and effective single ...

Nuclear reactions in nuclear matter
Nuclear Physics, 1966Abstract A number of topics in nuclear reaction theory are examined from the point of view of the liquid drop model. It is shown that, although the absolute value of the nucleon strength function at low energies has significance for high-energy experiments, it cannot be deduced from low-energy elastic scattering experiments, since the energy ...

Relativistic nuclear structure. I. Nuclear matter
Physical Review C, 1990The formalism for the Dirac-Brueckner approach to the nuclear many-body problem is described including its basis in relativistic two-nucleon scattering. A family of relativistic meson-exchange potentials is constructed which (apart from the usual coupling terms for heavy mesons) apply the pseudovector (gradient) coupling for the interaction of ...

The Exploration of Hot Nuclear Matter
Science, 2012The Primordial Soup Protons and neutrons were originally thought to be indivisible, but we now know that they have constituent parts—quarks. Quarks are bound together tightly through gluons and can only come apart under extreme conditions—conditions believed microseconds after the Big Bang to have formed a hot, dense “soup” of ...

Density fluctuations in nuclear matter
Il Nuovo Cimento A, 1975Variational computations of the binding energy per particle for various models of nuclear matter are reported. The main purpose is to compare the results corresponding to a «semi-crystallic» structure characterized by correlated density fluctuations of the four spin-isospin nucleon types, with those corresponding to the standard «Fermi gas» homogeneous

Soliton formation in nuclear matter
Physical Review C, 1992The propagation of a density disturbance in nuclear fluid is considered for the case when the nuclear equation of state is derived from a Skyrme-type effective nucleon-nucleon potential. It is shown that the velocity-dependent terms of this potential are responsible for the possible formation of solitary waves in nuclear matter.
