Stringy Tachyonic Instabilities of Non-Supersymmetric Ricci Flat Backgrounds
Bobby Samir Acharya, Gerardo Aldazabal, Eduardo Andrés +3
Superstring/M-theory compactified on compact Ricci flat manifolds have recently been conjectured to exhibit instabilities whenever the metrics do not have special holonomy. We use…

Particle models from orientifolds at Gepner-orbifold points
G. Aldazabal, E. C. Andrés, J. E. Juknevich
We consider configurations of stacks of orientifold planes and D-branes wrapped on a non trivial internal space of the structure {(Gepner model)^{c=3n} x T^{2(3-n)}}/Z_N, for n=1,2…

Type IIB orientifolds on Gepner points
Gerardo Aldazabal, Eduardo C. Andrés, Mauricio Leston +1
We study various aspects of orientifold projections of Type IIB closed string theory on Gepner points in different dimensions. The open string sector is introduced, in the usual co…
