Leading soft theorem for multiple gravitini
AbstractWe compute leading soft theorem for multiple gravitini (and gravitons) in an arbitrary theory of supergravity with an arbitrary number of finite energy particles by extending Sen’s approach [1,...

AbstractWe analyze the localization equations relevant to the quantum entropy of spinning supersymmetric black holes in five-dimensional asymptotically flat space. The precise problem is to classify...
View ArticleQuantum gravity from timelike Liouville theory
AbstractA proper definition of the path integral of quantum gravity has been a long- standing puzzle because the Weyl factor of the Euclidean metric has a wrong-sign kinetic term. We propose a...

AbstractWe show that the Atiyah-Patodi-Singer η-invariant can be related to the temperature-dependent Witten index of a noncompact theory and give a new proof of the APS theorem using scattering...

AbstractWe compute the Hermitian sector of the relative BRST cohomology of the spacelike and timelike Liouville theories with generic real central charge cL in each case, coupled to a spacelike Coulomb...

AbstractThe degeneracies of single-centered dyonic \( \frac{1}{4} \)-BPS black holes (BH) in Type II string theory on K3×T2 are known to be coefficients of certain mock Jacobi forms arising from the...

AbstractWe review and extend results on higher-curvature corrections to different configurations describing a superposition of heterotic strings, KK monopoles, solitonic 5-branes and momentum waves....

AbstractIn this article, we present a systematic analysis of the so-called perturbatively flat flux vacua (PFFV) for the mirror Calabi-Yau (CY) 3-folds (\( {\overset{\sim }{X}}_3 \)) with h1,1(\(...

AbstractModuli 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...

AbstractIn this article, we present a classification for the divisor topologies of the projective complete intersection Calabi-Yau (pCICY) 3-folds realized as hypersurfaces in the product of complex...

AbstractIn this work we investigate the moduli stabilisation problem and the requirements for de Sitter vacua within the framework of type IIB string theory. Using perturbative effects arising from the...
