“…In particular, we should certainly be able to accommodate type IIB as well as IIA within the framework presented, and we can also work with orientifold actions which are asymmetric on the fiber (compare for instance with the models of [53]). Furthermore, heterotic string theory on a torus or type II on K3 fibers can also be covered in this framework, since the duality groups in those situations are well-understood.…”

Type IIA toroidal orientifolds offer a promising toolkit for model builders, especially when one includes not only the usual fluxes from NS-NS and R-R field strengths, but also fluxes that are T-dual to the NS-NS three-form flux. These new ingredients are known as metric fluxes and non-geometric fluxes, and can help stabilize moduli or can lead to other new features. In this paper we study two approaches to these constructions, by effective field theory or by toroidal fibers twisted over a toroidal base. Each approach leads us to important observations, in particular the presence of D-terms in the four-dimensional effective potential in some cases, and a more subtle treatment of the quantization of the general NS-NS fluxes. Though our methods are general, we illustrate each approach on the example of an orientifold of T 6 /Z 4 .

“…For type IIA case, we will analyze in a similar way as in [12] and find a few solutions involving permutation orientifolds using the simple relations between the charges of D-branes and orientifolds in minimal models. For type IIB we see that the charges of D-branes and orientifolds are summarized into simple polynomials as was discussed in [4,16,22,43].…”

In tensor products of a left-right symmetric CFT, one can define permutation orientifolds by combining orientation reversal with involutive permutation symmetries. We construct the corresponding crosscap states in general rational CFTs and their orbifolds, and study in detail those in products of affine U(1)2 models or N = 2 minimal models. The results are used to construct permutation orientifolds of Gepner models. We list the permutation orientifolds in a few simple Gepner models, and study some of their physical properties -supersymmetry, tension and RR charges. We also study the action of corresponding parity on D-branes, and determine the gauge group on a stack of parity-invariant D-branes. Tadpole cancellation condition and some of its solutions are also presented.

“…Some references used this argument to exclude this modulus from the start, or to argue against a large volume limit [1,14,4,71]. In this paper, we are not talking of the same object: we performed a change of variables from an ill-defined to a well-defined metric, and the volume modulus is the fluctuation with respect to this new metric.…”

The NSNS Lagrangian of ten-dimensional supergravity is rewritten via a change of field variables inspired by Generalized Complex Geometry. We obtain a new metric and dilaton, together with an antisymmetric bivector field which leads to a ten-dimensional version of the non-geometric Q-flux. Given the involved global aspects of non-geometric situations, we prescribe to use this new Lagrangian, whose associated action is well-defined in some examples investigated here. This allows us to perform a standard dimensional reduction and to recover the usual contribution of the Q-flux to the four-dimensional scalar potential. An extension of this work to include the R-flux is discussed. The paper also contains a brief review on non-geometry.
