quark matter

n.
A state of matter which may exist at extremely high temperatures and densities, composed of quarks and gluons moving freely and not bound together within hadrons. Quark matter may have existed shortly after the Big Bang, may exist in the cores of neutron stars, and may be produced by the collision of two atomic nuclei at extremely high energy. Also called quark-gluon plasma.

Summary: TEHRAN (FNA)- Quark matter -- an extremely dense phase of matter made up of subatomic particles called quarks -- may exist at the heart of neutron stars.

They will present their latest results at the 2012 Quark Matter conference, which starts today in Washington, DC.
This strange quark matter is believed to be the most stable form of matter that can possibly exist in the universe.
Among the topics are nuclear magnetic resonance, from electron interaction to nuclear superfluidity, resistance in superconductors, novel phases of vortices, predicting and explaining Tc and other properties of BCS superconductors, a theory perspective on the evolution of high-temperature superconductivity, superfluidity in a gas of strongly interacting fermions, and BCS from nuclei and neutron stars to quark matter and cold atoms.
QCD experts have predicted the existence of chunks of Strange Quark Matter (SQM) [20].
Researchers working in physics, from the US, Europe, Brazil, Mexico, and Japan discuss Cooper pairs, superconductivity in highly correlated systems, the behavior of the Bose Einstein condensation critical temperature, the plasmon exchange model in carbon nanotubes, thermodynamic properties of point node superconductors, theory of the thermopower in YBCO, high-temperature superconductivity in carbon nanotubes, and magnetism and quark matter.
The findings of the PHENIX experiment -- aided by the Relativistic Heavy Ion Collider (RHIC) accelerator -- will be publicly announced during an international conference, Quark Matter 2002, that opened Thursday in Nantes, France.
QGP created at RHIC have a very low viscosity to entropy ratio, i.e., [eta]/S [greater than or equal to] l/4[pi] [4-9], and in the nonperturbative domain of QCD, with temperature close to [T.sub.c], the quark matter in the QGP phase is strongly interacting.
The results were released at the Quark Matter Conference recently held in Annecy, France.
