Marginal deformations of vacua with massive boson-fermion degeneracy symmetry
Florakis, Ioannis G.; Kounnas, Costas; Toumbas, Nicolaos K. (2010)Two-dimensional string vacua with Massive Spectrum boson-fermion Degeneracy Symmetry, [MSDS]d=2, are explicitly constructed in Type II and Heterotic superstring theories. The study of their moduli space indicates the ...

Non-singular string cosmology in a 2d hybrid model
Florakis, Ioannis G.; Kounnas, Costas; Partouche, Hervé; Toumbas, Nicolaos K. (2011)The existence of non-singular string cosmologies is established in a class of two-dimensional supersymmetric Hybrid models at finite temperature. The left-moving sector of the Hybrid models gives rise to 16 real (N4=4) ...
