A bstractIn the context of type IIB orientifold compactification with the presence of (non-)geometric fluxes, we conjecture a modular completed version of the generalized flux-orbits of various NS-NS and RR fluxes. Subsequently, considering two explicit examples with frozen complex structure moduli, we illustrate the utility of these new flux orbits in a very compact rearrangement of the four dimensional effective scalar potential. 

Reading off the nongeometric scalar potentials via the topological data of the compactifying Calabi-Yau manifolds

In the context of studying the 4D effective potentials of type IIB non-geometric flux compactifications, this article has a twofold goal. First, we present a modular invariant symplectic

A dictionary for the type II non-geometric flux compactifications

We study the T -dual completion of the four-dimensionalN = 1 type II effective potentials in the presence of (non-)geometric fluxes. First, we invoke a cohomology version of the T -dual

Systematics of type IIB moduli stabilisation with odd axions

Abstract Moduli stabilisation in superstring compactifications on Calabi-Yau orientifolds remains a key challenge in the search for realistic string vacua. In particular, odd moduli arising from the

A symplectic rearrangement of the four dimensional non-geometric scalar potential

A bstractWe present a symplectic rearrangement of the effective four-dimensional non-geometric scalar potential resulting from type IIB superstring compactification on Calabi Yau orientifolds. The

Type IIB Flux Vacua and Tadpole Cancellation

We consider flux vacua for type IIB orientifold compactifications and study their interplay with the tadpole‐cancellation condition. As a concrete example we focus on T6/Z2×Z2 , for which we find

Dictionary for the type II nongeometric flux compactifications

We study the $T$-dual completion of the four-dimensional ${\cal N}=1$ type II effective potentials in the presence of (non-)geometric fluxes. First, we invoke a cohomology version of the $T$-dual

Rigid nongeometric orientifolds and the swampland

Non-geometric flux compactifications with frozen complex structure moduli have been recently studied for several phenomenological purposes. Motivated by the same, we analyze the possibility of

On $T$-dual pairs of stable AdS/dS vacua ?

We present T -dual pairs of tachyon free (stable) AdS as well as dS solutions in the context of type II orientifold compactifications. In our construction, the type IIA setting is a purely geometric

Revisiting the two formulations of Bianchi identities and their implications on moduli stabilization

A bstractIn the context of non-geometric type II orientifold compactifications, there have been two formulations for representing the various NS-NS Bianchi-identities. In the first formulation, the



Slow-roll inflation in non-geometric flux compactification

By implementing a genetic algorithm we search for stable vacua in Type IIB non-geometric flux compactification on an isotropic torus with orientifold 3-planes. We find that the number of stable dS

The effective action of double field theory

A bstractWe perform a generalized Scherk-Schwarz dimensional reduction of Double Field Theory on a twisted double torus. The four dimensional effective action is shown to exactly reproduce the

Duality orbits of non‐geometric fluxes

Compactifications in duality covariant constructions such as generalised geometry and double field theory have proven to be suitable frameworks to reproduce gauged supergravities containing

D-terms from generalized NS-NS fluxes in type II

Orientifolds of type II string theory admit a certain set of generalized NS-NS fluxes, including not only the three-form field strength H, but also metric and non-geometric fluxes, which are related

Relating double field theory to the scalar potential of N = 2 gauged supergravity

A bstractThe double field theory action in the flux formulation is dimensionally reduced on a Calabi-Yau three-fold equipped with non-vanishing type IIB geometric and non-geometric fluxes. First, we

We establish the precise correspondence between Type-IIA flux compactifications preserving an exact or spontaneously broken = 4 supersymmetry in four dimensions, and gaugings of their effective = 4
