Abstract:We derive the Euclidean time formulation for the equilibrium canonical ensemble of the type IIA and type IIB superstrings, and the spinð32Þ=Z 2 heterotic string. We compactify on R 8 × T 2 , and twist by the Neveu-Schwarz sector antisymmetric 2-form B-field potential, spontaneously breaking supersymmetry at low temperatures, while preserving the tachyon-free low-energy gravitational field theory limit. We verify that the super partners of the massless dilaton-graviton multiplet obtain a mass which is linear in… Show more
“…But note that the value of the self-dual temperature comes from the T-duality transformation formula, equation (18), that holds as long as the target space has an compactified Euclidean time direction. Also, there are thermal string constructions free of Hagedorn instabilities (see for example [35,36,37,38]) and the arguments of the previous section can be applied for the bosonic sector of them. Also, there could be potential applications to Euclidean type II * theories 5 (see [39] and references therein), as they can be seen as T-dual to type II strings (though in the time-like direction).…”
It is argued that the Unruh effect may be interpreted as a duality of a theory on different backgrounds. This issue is revisited in String Theory in the path integral formalism. By using T-duality and the Unruh effect, the T-dual transformation for acceleration is investigated and a maximum effective physical acceleration for observers in String Theory is found.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
