Positivity and Dense Matter

Deog Ki Hong and Stephen D.H. Hsu 1 Department of Physics, Pusan National University, Pusan 609-735, Korea [email protected] 2 Department of Physics, University of Oregon, Eugene OR 97403-5203 [email protected] (Dated: June 4, 2005) Abstract We elaborate on previous results concerning the positivity of the Euclidean path integral measure for low-energy modes in dense fermionic matter. We ...

Multi fluidity and Solitary wave stability in cold quark matter: core of dense astrophysical objects

Considering the magneto-hydrodynamic equations in a non-relativistic multi uid framework, we study the behavior of small amplitude perturbations in cold quark matter. Magneto-hydrodynamic equations, along with a suitable equation of state for the cold quark matter, are expanded using the reductive perturbation method. It is shown that in small amplitude approximation, such a medium should be co...

Illuminating dense quark matter.

We imagine shining light on a lump of cold dense quark matter, in the color-flavor locked phase and therefore a transparent insulator. We calculate the angles of reflection and refraction, and the intensity of the reflected and refracted light. Although the only potentially observable context for this phenomenon (reflection of light from and refraction of light through an illuminated quark star...

Neutral Dense Quark Matter

The ground state of dense up and down quark matter under local and global charge neutrality conditions with β-equilibrium has at least four possibilities: normal, regular 2SC, gapless 2SC phases, and mixed phase composed of 2SC phase and normal components. The discussion is focused on the unusual properties of gapless 2SC phase at zero as well as at finite temperature.

Causality in dense matter.

The possibility of non-causal signal propagation is examined for various theories of dense matter. This investigation requires a discussion of definitions of causality, together with interpretations of spacetime position. Specific examples are used to illustrate the satisfaction or violation of causality in realistic calculations. Typeset using REVTEX 1
