Open AccessTidal resonances for fuzzballs
We study the gravitational tidal response of D1D5, Top Star and (1,0,n) strata horizonless geometries. We find that the tidal interactions in fuzzball geometries, unlike in the case of black holes, exhibits a ...

Open AccessPost Newtonian emission of gravitational waves from binary systems: a gauge theory perspective
Using the AGT correspondence and localization, we derive a combinatorial formula for the Post-Newtonian expansion of the wave form describing the gravitational emission from binary systems made of objects of e...

Open AccessOn irregular states and Argyres-Douglas theories
Conformal theories of the Argyres-Douglas type are notoriously hard to study given that they are isolated and strongly coupled thus lacking a lagrangian description. In flat space, an exact description is prov...

Open AccessPartition functions of non-Lagrangian theories from the holomorphic anomaly
The computation of the partition function in certain quantum field theories, such as those of the Argyres-Douglas or Minahan-Nemeschansky type, is problematic due to the lack of a Lagrangian description. In th...

Open AccessCFT description of BH’s and ECO’s: QNMs, superradiance, echoes and tidal responses
Using conformal field theory and localization tecniques we study the propagation of scalar waves in gravity backgrounds described by Schrödinger like equations with Fuchsian singularities. Exact formulae for t...

Open AccessStrings in bubbling geometries and dual Wilson loop correlators
We consider a fundamental string in a bubbling geometry of arbitrary genus dual to a half-supersymmetric Wilson loop in a general large representation R of the SU(N) gauge group in

Exact results in \( \mathcal{N}=2 \) gauge theories
We derive exact formulae for the partition function and the expectation values of Wilson/’t Hooft loops, thus directly checking their S-duality transformations. We focus on a special class of

U-folds as K3 fibrations
We study \( \mathcal{N}=2 \) four-dimensional flux vacua describing intrinsic non- perturbative systems of 3 and 7 bran...

Deformed Seiberg-Witten curves for ADE quivers
We derive Seiberg-Witten like equations encoding the dynamics of \( \mathcal{N}=2 \) ADE quiver gauge theories in presence of a non-trivial Ω-background along a two dimensional p...

Stückelino dark matter in anomalous U(1)′ models
We study a possible dark matter candidate in the framework of a minimal anomalous U(1)′ extension of the MSSM. It turns out that in a suitable decoupling limit the Stückelino, the fermionic degree of freedom of t...

Stringy instanton corrections to \( \mathcal{N} = 2 \) gauge couplings
We discuss a string model where a conformal four-dimensional \( \mathcal{N} = 2 \) gauge theory receives corrections to...
