Charge and critical density of strange quark matter
The last 20 years have witnessed an ever-increasing interest in strange quark matter (SQM) [1]. Early in 1970’s [2], it had already been known that the appearance of s fraction in two flavor quark droplets provides an additional degree of freedom, and thus could lower the energy of the system. In 1984, Witten conjectured that quark matter with strangeness per baryon of order unity might be boun...
متن کاملCritical Exponents of Erbium
The exponent P that describes the sinusoidally modulate d * paramagnetic phase transition crosses over from a value of 0.39 near TN to a mean field value away from TN. Electrical resistivity measurements near TN are given for the c axis and the critical behaviour is discussed. Erbium orders below its NBel temperature TN= 85 K with its spins directed along the c axis of the hcp crystal and with ...
متن کاملCritical Line for H-Superfluidity in Strange Quark Matter?
In QCD, there is a phase transition to a color superconducting phase at high quark density and low temperature [1–24]. At densities of interest for the collisions of heavy ions or quark stars, “2+1” flavors of quarks — up, down, and strange — enter. The order of the phase transition to a color superconducting phase at zero temperature, as function of the quark chemical potential, was analyzed p...
متن کاملON QUASILINEAR ELLIPTIC SYSTEMS INVOLVING MULTIPLE CRITICAL EXPONENTS
In this paper, we consider the existence of a non-trivial weaksolution to a quasilinear elliptic system involving critical Hardyexponents. The main issue of the paper is to understand thebehavior of these Palais-Smale sequences. Indeed, the principaldifficulty here is that there is an asymptotic competition betweenthe energy functional carried by the critical nonlinearities. Thenby the variatio...
متن کاملNuclear multifragmentation critical exponents.
In a recent Letter [1] the EoS collaboration presented data of fragmentation of 1 A GeV gold nuclei incident on carbon. By analyzing moments of the fragment charge distribution, the authors claim to determine the values of the critical exponents γ, β, and τ for finite nuclei. These data represent a crucial step forward in our understanding of the physics of nuclear fragmentation. However, as we...
