    Global consistency condition of string theory plays important role in obtaining vacua of string theory.
    It does not only restrict possible vacua, but also suggest that many vacua are connected, if the systems are protected by SUSY.
    We visit some examples in heterotic orbifold and F-theory, focusing on the small instanton transitions and their duals.

    We study implications of non-local interactions, assuming an effective gaussian localization of interaction vertices. We present the analytical form of a transition amplitude, and discuss possible phenomenological applications of this approach.

    In this talk, I will present an explicit string realisation of a cosmological inflationary scenario within the framework of type IIB flux compactifications in the presence of three magnetised D7-brane stacks. Inflation takes place around a metastable de Sitter vacuum. The scalar potential of the inflaton, identified with the volume modulus, exhibits a very shallow minimum. Inflation ends due...

    We consider a class of integrable deformations of current algebra/coset CFTs by current/parafermion bilinears, known as \lambda-deformed models. We dynamically promote the deformation parameters by introducing time as an extra coordinate and we enforce conformal invariance at one-loop order. The derived model obeys a system of non-linear second-order ordinary differential equations and by...

    We present a GUT model based on the conformal superalgebra su(2,2|N). The model is based on an implementation of supersymmetry where matter fields are in the adjoint representation. We will discuss some of the particularities of the model and we will compare to other susy and nonsusy GUT schemes.

    New Developments in String Theory

    We discuss flux compactifications of massive Type IIA string theory on G2 spaces with O2/O6-planes to three dimensions. We start by presenting the setup of allowed fluxes, internal geometry and equations of motion and after compactification we achieve N=1 and N=0 $\text{AdS}_3$ vacua with scale that can be parametrically decoupled from the KK modes. We use the smeared approximation description...

    This talk focuses on a collection of ideas that explain why the Standard Model (SM) should be completed by a graviton, graviphotons, axions, and neutrinos (and maybe other stuff) emerging from a hidden sector.
    This task will be accomplished in a novel framework, where the SM is coupled to a holographic theory. The new particles will be composites and, in almost all cases, are distinct...

    Gravity and Supergravity

    We generalize the Quantum Geometric Tensor by replacing a Hamiltonian with a modular Hamiltonian. The symmetric part of the Quantum Geometric Tensor provides a Fubini-Study metric, and its anti-symmetric sector gives a Berry curvature. Our generalization dubbed Quantum Modular Geometric Tensor gives the metric and curvature of a Kinematic Space. We also use the result of the identity Virasoro...
