“…it is not clear which minima of GSUGRA belong to the string landscape and which to the swampland. This work can be considered as the continuation of a series of papers that started with the construction of Gepner models [20][21][22][23], their extension by the simple current technique [24,25] for constructing ACFTs [26][27][28][29][30], and the recent attempt [16] to relate some of these four-dimensional ACFTs to minima of N = 2 GSUGRA partially-broken to N = 1.…”

We study asymmetric simple-current extensions of Gepner models in dimensions D = 4, 6, 8 with at least eight supercharges in the right-moving sector. The models obtained in an extensive stochastic computer search belong to a small number of different classes. These classes can be categorized as dimensional reductions, asymmetric orbifolds with (−1) F L , extra gauge enhancement and as coming from the super Higgs-effect. Models in the latter class are particularly interesting, as they may correspond to non-geometric flux compactifications.

“…[1]). A large class of non-geometric models with all supercharges arising from left-movers based on Calabi-Yau compactifications in the Landau-Ginsburg regime were recently studied in [2][3][4], related to older works [5,6]. These models have a volume modulus for the target space which is fixed by the construction, so that one cannot continuously take a large-volume limit, and are intrinsically non-geometric with the number of massless moduli typically being very small.…”

“…The orbifold is by transformations (γ 1 , t 1 ), (γ 2 , t 2 ) where the automorphism γ i of degree p i is combined with a shift t i on the i'th circle of the T 2 by 2π/p i (i = 1, 2). Then at a fixed point the twisted reduction reduces to a freely-acting asymmetric orbifold of the K3 × T 2 compactification, resulting in the simplest cases in the asymmetric Gepner models of [2].…”

We present a new class of dualities relating non-geometric Calabi-Yau compactifications of type II string theory to T-fold compactifications of the heterotic string, both preserving four-dimensional N = 2 supersymmetry. The non-geometric Calabi-Yau space is a K3 fibration over T 2 with non-geometric monodromies in the duality group O(Γ 4,20 ); this is dual to a heterotic reduction on a T 4 fibration over T 2 with the O(Γ 4,20 ) monodromies now viewed as heterotic T-dualities. At a point in moduli space which is a minimum of the scalar potential, the type II compactification becomes an asymmetric Gepner model and the monodromies become automorphisms involving mirror symmetries, while the heterotic dual is an asymmetric toroidal orbifold. We generalise previous constructions to ones in which the automorphisms are not of prime order. The type II construction is perturbatively consistent, but the naive heterotic dual is not modular invariant. Modular invariance on the heterotic side is achieved by including twists in the circles dual to the winding numbers round the T 2 , and this in turn introduces non-perturbative phases depending on NS5-brane charge in the type II construction.

“…The main objective of the papers [19,20] was to analyze this question in the framework of asymmetric Gepner models. While there are other methods [21], the easiest way to construct an asymmetric Gepner model is the simple current method [41,42,43,44,45,46,47,22]. More concretely we added one or more simple currents to the partition function of the Gepner model (2.4) such that the full partition function becomes…”

Recent progress on the relation between asymmetric conformal field theories and vacua of gauged supergravities is reviewed. This includes a classification of asymmetric Gepner models in 8D, 6D and 4D with at least eight supercharges, and how they can be categorized by just a few mechanisms including the super Higgs-effect. The latter is a prerequisite for the identification with non-geometric flux compactifications. We also highlight our findings for the identification of 4D asymmetric Gepner models with N = 1 supersymmetry with Minkowski vacua of N = 2 GSUGRA.
