Kaon condensation in high-density quark matter.
We point out that the problem of kaon condensation in dense hadronic matter can be addressed in perturbative QCD. Indeed, perturbative calculations suggest that negative kaons are condensed in high-density quark matter if the presence of electrons is taken into account. This observation sheds new light on the proposal that the low-density hyperon and high-density quark matter phases of QCD are ...
متن کاملDoes Raising High-Density Lipoprotein Matter?
The well-documented capacity of alcohol consumption to increase levels of high-density lipoprotein (HDL) cholesterol1 has generated attempts to assess the extent to which this effect might contribute to the reduced incidence of coronary heart disease (CHD) that has been observed in moderate consumers of alcohol.2 Several reports based on multiple regression models in observational cohort studie...
متن کاملStrongly Coupled Condensate of High Density Matter
Arguments are summarized, that neutral matter made of helium, carbon, etc., should form a quantum liquid at the above-atomic but below-nuclear densities for which the charged spin-0 nuclei can condense. The resulting substance has distinctive features, such as a mass gap in the bosonic sector and a gap-less spectrum of quasifermions, which determine its thermodynamic properties. I discuss an ef...
متن کاملStrongly Interacting Matter at High Energy Density∗
This lecture concerns the properties of strongly interacting matter (which is described by Quantum Chromodynamics) at very high energy density. I review the properties of matter at high temperature, discussing the deconfinement phase transition . At high baryon density and low temperature, large Nc arguments are developed which suggest that high baryonic density matter is a third form of matter...
متن کاملHigh Density Quark Matter and the
We consider the most general four fermion operators in QCD for two and three massless avors and study their renormalization in the vicinity of the Fermi surface. We show that, asymptotically, the largest coupling corresponds to scalar diquark condensation. Asymptotically the direct and iterated (molecular) instanton interactions become equal. We provide simple arguments for the form of the oper...
