## Abstract We consider four dimensional heterotic string backgrounds for which supersymmetry is spontaneously broken via the Scherk‐Schwarz mechanism on an internal spatial cycle and by finite temperature effects. We concentrate on initially flat backgrounds with N = 4 and N = 2 amount of supersym
## Abstract We review the cosmology induced by finite temperature and quantum effects on non‐supersymmetric string models. We show the evolution is attracted to radiation‐like solutions after the Hagedorn era and before the electroweak phase transition. This mechanism generates a hierarchy between
