A new formalism to calculate the in-medium chiral condensate is presented. At lower densities, this approach leads to a linear expression. If we demand a compatibility with the famous model-independent result, then the pion-nucleon sigma term should be six times the average current mass of light quarks. QCD-like interactions may slow the decreasing behavior(More)
The color-flavor locked (CFL) phase of strangelets is investigated in a quark mass density-dependent model. Parameters are determined by stability arguments. It is concluded that three solutions to the system equations can be found, corresponding, respectively, to positively charged, negatively charged, and nearly neutral CFL strangelets. The charge to(More)
During the past twelve years, great improvements in finite element solution algorithms have been made. In 1990, a simple coax to waveguide adapter took sixteen hours to solve for a single frequency point on a Sun II computer; today the same part is solved for a fast sweep of 10 or more frequency points on a Pentium IV computer in 6 seconds. This is speed(More)
