IN two previous notes1, Prof. Max Born and I have shown that one can obtain a theory of superconductivity by taking account of the fact that the interaction of the electrons with the ionic lattice is appreciable only near the boundaries of Brillouin zones, and particularly strong near the corners of these. This leads to the criterion that the metal should be superconductive if a set of corners of a Brillouin zone is lying very near the Fermi surface, considered as a sphere, which limits the region in the momentum space completely filled with electrons.

The treatment of first-order phase transitions for standard grand unified theories is shown to break down for models with radiatively induced spontaneous symmetry breaking. It is argued that proper analysis of these transitions which would take place in the early history of the universe can lead to an explanation of the cosmological homogeneity, flatness, and monopole puzzles.

Cosmology for Grand Unified Theories with Radiatively Induced Symmetry Breaking

We investigate the internal structure of cold dark matter halos using high resolution N-body simulations. As the mass and force resolution are increased, halo density profiles become steeper, asymp-toting to a slope of ∼ −4/3 in the central regions and may not have converged to a unique result. At our highest resolution we have nearly 3 million particles within the virial radius, R 200 , and force softening that is ∼ 0.2%R 200. This resolution has also allowed us to resolve a large part of the overmerging problem-we find over 1000 surviving dark halos orbiting within a single cluster potential. These data have given us unprecedented insights into the dynamics and structure of " halos within halos " , allowing us for the first time, to compare the distribution of dark matter with observations of galaxies in clusters.

The Structure of Cold Dark Matter Halos

Much attention in elementary particle physics has beenpaid recently to the possible degeneracy of vacuumand the respective spontaneous breaking of varioussymmetries. The most direct consequence of the vacuumdegeneracy is the appearance of zero-mass particles, theso-called Goldstone particles [1].Of all the presently known elementary particles, onlyneutrinos, photons, and gravitons have zero mass. Thelast two, however, correspond to gauge fields and donot require apparently the vacuum degeneracy for theirdescription. Therefore, a neutrino is the only particle,whose existence can be directly related to the vacuumdegeneracy.The purpose of this study is to point out that thehypothesis that a neutrino is the Goldstone particle leadsto a definite form of the interaction of a neutrino bothwith other neutrinos and with all other particles. Theinteraction is fully defined by a single phenomenologicalcoupling constant and is universal in this sense.To determine the type of a symmetry, whosespontaneous violation causes the degeneracy of vacuumand the corresponding properties of a neutrino asthe Goldstone particle, let us consider the symmetryproperties of the equation for a free neutrino
