Description
Most of the mechanisms for moduli stabilization in String Theory involve R-R fluxes that can only be treated in the supergravity approximation. Non-geometric vacumm configurations with L-R asymmetric `T-duality' twists and shifts allow to stabilize closed string moduli in a controllable way. Peculiarities of bound-states of D-branes in these backgrounds will be discussed in view of phenomenological applications to models with open and unoriented strings.
