| Abstract | Large charge density, unlike high temperature, may lead to nonrestoration of global and gauge symmetries. Supersymmetric GUTs with the appealing scenario of unification scale being generated dynamically naturally contain global continuous $R$ symmetries. We point out that the presence of a large $R$ charge in the early Universe can lead to GUT symmetry nonrestoration. This provides a simple way out of the monopole problem. |
