Double fibration in G-theory and the cobordism conjecture
Cesar Damian, Oscar Loaiza-Brito, Víctor M. López-Ramos
We investigate Type IIB compactifications with spatially varying fluxes and dilaton profiles in the setting of dynamical cobordism. In particular, we analyze a G-theory motivated c…
An effective description of the instability of coherent states of gravitons in string theory
Cesar Damian, Oscar Loaiza-Brito
We study the dynamics of a coherent state of closed type II string gravitons within the framework of the Steepest Entropy Ascent Quantum Thermodynamics, an effective model where th…
Galois groups of uplifted de Sitter vacua
Cesar Damian, Oscar Loaiza-Brito
We compute the Galois group of a polynomial whose roots are determined by the critical points of a scalar potential in type IIB compactifications. We focus our study on certain per…
Metastable vacua from torsion and machine learning
Cesar Damian, Oscar Loaiza-Brito
By implementing an error function on a Machine Learning algorithm we look for minimal conditions to construct stable Anti de Sitter and de Sitter vacua from dimensional type IIB St…
Inflationary implications of the Covariant Entropy Bound and the Swampland de Sitter Conjectures
Dibya Chakraborty, Cesar Damian, Alberto Gonzalez Bernal +1
We present a proposal to relate the de Sitter Conjecture (dSC) to the Covariant Entropy Bound (CEB). By assuming an early phase of accelerated expansion where the CEB is satisfied,…
Testing Swampland Conjectures with Machine Learning
Nana Cabo Bizet, Cesar Damian, Oscar Loaiza-Brito +2
We consider Type IIB compactifications on an isotropic torus threaded by geometric and non geometric fluxes. For this particular setup we apply supervised machine learning te…
Quantum implications of non-extensive statistics
Nana Cabo Bizet, César Damián Ascencio, Octavio Obregón +1
Exploring the analogy between quantum mechanics and statistical mechanics we formulate an integrated version of the Quantropy functional [1]. With this prescription we compute the…
Some remarks on the dS conjecture, fluxes and K-theory in IIB toroidal compactifications
Cesar Damian, Oscar Loaiza-Brito
In this note, we present a scenario in which the existence of dS vacua is jeopardized by topological transitions between non-BPS branes and fluxes in type IIB toroidal compactifica…
Leaving the Swampland: Non-geometric fluxes and the Distance Conjecture
Nana Cabo Bizet, Cesar Damian, Oscar Loaiza-Brito +1
We study a Type IIB isotropic toroidal compactification with non-geometric fluxes. Under the assumption of a hierarchy on the moduli, an effective scalar potential is constructed s…
Two-field axion inflation and the swampland constraint in the flux-scaling scenario
Cesar Damian, Oscar Loaiza-Brito
Based on the flux-scaling scenario we study a model consisting on Type IIB string theory compactified on a Calabi-Yau manifold with a frozen complex structure in the presence of ge…
Meromorphic Flux Compactification
Cesar Damian, Oscar Loaiza-Brito
We present exact solutions of four-dimensional Einstein's equations related to Minkoswki vacuum constructed from Type IIB string theory with non-trivial fluxes. Following recent wo…
The Flux-Scaling Scenario: De Sitter Uplift and Axion Inflation
Ralph Blumenhagen, Cesar Damian, Anamaria Font +2
Non-geometric flux-scaling vacua provide promising starting points to realize axion monodromy inflation via the F-term scalar potential. We show that these vacua can be uplifted to…
Type IIB flux vacua from G-theory II
Philip Candelas, Andrei Constantin, Cesar Damian +2
We find analytic solutions of type IIB supergravity on geometries that locally take the form with a generalised complex manifold. The…
Type IIB flux vacua from G-theory I
Philip Candelas, Andrei Constantin, Cesar Damian +2
We construct non-perturbatively exact four-dimensional Minkowski vacua of type IIB string theory with non-trivial fluxes. These solutions are found by gluing together, consistently…
More stable dS vacua from S-dual non-geometric fluxes
Cesar Damian, Oscar Loaiza-Brito
Stable vacua obtained from isotropic tori compactification might not be fully stable provided the existence of runaway directions in the Kaehler directions of anisotropy. By implem…
Slow-Roll Inflation in Non-geometric Flux Compactification
Cesar Damian, Luis R. Diaz-Barron, Oscar Loaiza-Brito +1
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 num…
