Universe Evolution

Similarities between cosmological scenarios on the Universe evolution after “Big Bang” and the behavior of the highly excited nuclear matter formed in relativistic nuclear collisions, immediately after collisions, are considered to do an estimation of a “microscopic Hubble parameter/constant” for the expansion rate in relativistic nuclear collisions, similar with the cosmological Hubble constant. Temporal connections between the evolution of the nuclear matter after impact and the scenarios on the Universe evolution after “Big Bang” are introduced. Experimental results on participants, fireball sizes (identical particle interferometry), densities, particle spectra and temperatures have been used. A “Hubble scale” for temporal evolution can be obtained. Satisfactory agreement with Buda-Lund model estimations has been obtained.

This paper presents our study of the presence of the unstable critical point in spontaneous symmetry breaking (SSB) in the framework of Ginzburg–Landau (G-L) free energy. Through a 3D Ising spin lattice simulation, we found a zone of hysteresis where the unstable critical point continued to exist, despite the system having entered the broken symmetry phase. Within the hysteresis zone, the presence of the kink–antikink SSB solitons expands and, therefore, these can be observed. In scalar field theories, such as Higgs fields, the mass of this soliton inside the hysteresis zone could behave as a tachyon mass, namely as an imaginary quantity. Due to the fact that groups Ζ(2) and SU(2) belong to the same universality class, one expects that, in future experiments of ultra-relativistic nuclear collisions, in addition to the expected bosons condensations, structures of tachyon fields could appear.
