| Abstract | In supersymmetric models with the run-away vacua or with the stable but nonsupersymmetric ground state there exist stable field configurations (vacua) which restore one half of supersymmetry and are characterized by constant positive energy density. The formal foundation for such vacua is provided by the central extension of the N = 1 superalgebra with the infinite central charge. In Ref. [1] we found a class of unconventional solutions, which exist in supersymmetric theories with a vacuum moduli space, and are characterized by (i) constant energy density; (ii) topological stability. They can be considered as a limiting case of the domain walls (sometimes we deal with the so-called constant phase configurations, sometimes with the winding phase configurations, see Sec. 5 of [1]). One half of supersymmetry may or may not be preserved on these solutions. Because of their topological stability they can become vacua of a theory breaking a part of the Lorentz invariance and supersymmetry. Thus, this is a particular realization of the dynamical compactification, the idea central in Ref. [1]. The existence of the topologically stable vacua with the purely gradient (constant) |
