Superstrings at high temperature
Abstract
The behavior of ten-dimensional superstrings at high temperatures is studied by use of the microcanonical ensemble. We focus on closed superstring theories. The massive string excitations alone have negative specific heat. Such a system can reach equilibrium with the zero modes of the string if the energy carried by zero modes is less than a given fraction of the total energy. The temperature can then exceed the Hagedorn temperature. Some consequences for the evolution of the universe are discussed.
