String instantons, fluxes and moduli stabilization
P. G. Camara, E. Dudas, T. Maillard +1
We analyze a class of dual pairs of heterotic and type I models based on freely-acting orbifolds in four dimensions. Using the adiabatic argument…
Magnetic Fluxes, NS-NS Field and Shifts in Four-Dimensional Orientifolds
Gianfranco Pradisi
We discuss the interplay between freely acting orbifold actions, discrete deformations and internal uniform magnetic fields in four-dimensional orientifold models.
Magnetized (Shift-)Orientifolds
Gianfranco Pradisi
We study four dimensional (shift)-orientifolds in presence of internal magnetic fields and NS-NS -field backgrounds, describing in some detail one explicit exam…
Geometrical Construction of Type I Superstring Vacua
Gianfranco Pradisi
The parameter-space orbifold construction of open and unoriented toroidal and (target-space) orbifold compactifications is briefly reviewed, with emphasis on the underlying geometr…
New Developments in Open - String Theories
Gianfranco Pradisi, Augusto Sagnotti
The study of string models including both unoriented closed strings and open strings presents a number of new features when compared to the standard case of models of oriented clos…
