On superdense superstring gases: A heretic string model approach

A simple model is proposed to describe a gas of free strings at very high energy density, particularly in connection with a recently discovered phase dominated by macroscopic strings. This phase appears at high energy density if open strings are forbidden. For oriented strings the probability densit...

Description
Summary:A simple model is proposed to describe a gas of free strings at very high energy density, particularly in connection with a recently discovered phase dominated by macroscopic strings. This phase appears at high energy density if open strings are forbidden. For oriented strings the probability density for strings in the energy interval ( E, E + d E) is d E / E in this phase. If open strings are allowed no such phase appears. The model is compared with superstring calculations, and relevant quantities are shown to agree. The model gives a simple and intuitively appealing picture of dense, free string gases. The effective string tension is also discussed and shown to vanish at the critical temperature.
