Description

Tadpole potentials are the leading manifestation of the absence of supersymmetry in non-supersymmetric string models. A remarkable consequence is that the notion of vacuum solutions becomes puzzling. Codimension-one vacua were originally proposed as an alternative to vacuum solutions for non-supersymmetric strings, although recent investigations have indicated different interpretations in some cases.
In this talk, I will review the known codimension-one vacua of non-supersymmetric strings and emphasize some of their peculiarities when interpreted as domain walls or as time-dependent backgrounds. I will also comment on T-dual models in which tadpole potentials are localized.
