In this talk, I will present a new formulation of the effective-one-body (EOB) dynamics, particularly well suited for incorporating post-Minkowskian information into waveform models for compact binaries. This is especially timely, as several groups worldwide are currently working to derive increasingly accurate post-Minkowskian results for the two-body problem. After motivating the shift in...

Chern-Simons-matter theories in 3 dimensions are known to display a plethora of Wilson loops that can be used to define 1-dimensional defect conformal field theories (dCFTs) living on their contours. In this talk we propose to discuss a few examples from an intricate web of RG flows connecting the dCFTs defined on the BPS and non-BPS Wilson loops of ABJM theory. We compute the anomalous...

During the last decade, the notion of an ’t Hooft anomaly has been generalised to the case of discrete symmetries. An interesting instance, discussed by Tanizaki, is the mixed anomaly between the discrete axial symmetry and the flavour and baryonic symmetries in massless QCD. In this talk, I will provide a derivation of this anomaly from a top-down holographic dual of QCD. I will show that the...

The poster describes the effect of introducing open string degrees of freedom (scalars and fluxes) associated with spacetime-filling branes/orientifold planes in dimensional reductions of massive type IIA supergravity on a 3-sphere with warping. The corresponding supergravity description in 7 dimensions needs extra vector multiplets coupled to the gravity multiplet and new embedding tensor...

Exploiting the analytic properties of the scattering amplitude, we provide an alternative but equivalent definition of the standard Mellin transform used to obtain celestial correlation functions. From this representation, we identify a celestial dispersion relation that relates the reduced correlation function to the poles and discontinuities of the bulk amplitude. By drawing an analogy with...

We investigate the dynamics and radiation of electrically charged black hole binaries within the post-Newtonian (PN) framework. We derive the conservative dynamics up to second post-Newtonian (2PN) order from a harmonic-coordinate Lagrangian incorporating both gravitational and electromagnetic interactions, and we compute the leading dissipative effects induced by charge. Furthermore, we...

The AdS/CFT correspondence provides us with the best working example of the holographic principle. The holographic principle is used to study quantum gravity observables living on the conformal boundary of space-time. For example, this has been applied in the AdS/CFT correspondence, where we studied that quantum gravity observables on the boundary of (d+1)-dimensional AdS space are equivalent...

We study the gravitational origin of the logarithmic term arising in the superconformal index of four-dimensional $\mathcal{N}=1$ SCFTs, both in the Cardy-like limit and in the large-$N$ limit, focusing on its interpretation in terms of discrete symmetries and saddle degeneracy. On the field-theory side, this contribution is associated with the spontaneous breaking of an electric...

Several simple asymptotically free chiral gauge theories are studied. The only “free parameters” of our models are the choice of the gauge group and the representations of the matter Weyl fermions,and the relative magnitudes of the renormalization-group (RG) energy scales $Λ_{i}$ associated with each gauge group. Equivalently, they can be chosen as small gauge coupling constants at an...

We revisit the one-loop logarithmic corrections to the partition function in 11-dimensional supergravity on $AdS_4 \times S^7$, providing a systematic lower-dimensional framework for precision holography. Starting from the 11d partition function, we perform a complete spherical harmonic decomposition of the supergravity field content on the internal manifold $S^7$, thus reducing the 11d...

In the thin wall approximation, we study a class of asymptotically AdS black holes which contain a spherically symmetric vacuum bubble with a different (positive or negative) cosmological constant. Collapsing, expanding, and static bubble solutions are considered. Among these, expanding bubbles with positive cosmological constant can provide a way to apply the AdS/CFT correspondence to...

Line defects pose a fundamental challenge for dualities in gauge theories. While it is known that field theories with radically different gauge groups can be dual at low energies, it is not yet fully understood how the presence of a line defect in one theory maps in the dual description. This conundrum was partially solved in the case of 3d theories with N=4 supersymmetry related by mirror...

String theory scattering amplitudes exhibit remarkable properties, most notably their ultraviolet softness, easily explained from a worldsheet perspective. From a target space perspective, these features arise from the infinite tower of massive excitations organized into Regge trajectories. Despite this rich structure, string amplitudes are not known in closed form beyond a few low-lying...

Supersymmetric localization is a powerful technique to get exact results from the path integral of a supersymmetric field theories defined on a compact manifold [1,2,3]. Localization relies on the definition of supersymmetric theories in curved space, which need to preserve part of the original supersymmetry existing in flat space. In the relativistic case, this problem was systematically...

We study universal features of defect correlation functions in supersymmetric defect CFTs, focusing on four-point functions of the displacement supermultiplet. By perturbing the leading-order correlators at strong coupling, we derive constraints that identify the operators exchanged at next-to-leading order. From this, we determine the conditions under which four-point functions of defect...

In the face of theoretical and experimental difficulties in directly probing string theory in its natural, high-energy regime, one hopes that its low-energy regime feature general properties arising from UV/IR mixing. Concretely, I will discuss how the infrared data - potentials, gauge couplings, Wilson coefficients - of gravitational effective theories arising from worldsheet string theory...

I will discuss a large class of supersymmetric solutions of Euclidean five-dimensional supergravity recently studied in 2507.12650 [hep-th]. These solutions admit an interpretation as saddle points of the gravitational path integral that computes a supersymmetric index. They possess a $\mathrm{U}(1)^3$ isometry and are characterized by a rod structure specifying the fixed loci of the...

The sausage model is a two-dimensional integrable deformation of the O(3) sigma model introduced by Fateev, Onofri and Zamolodchikov. In this talk I will explain how we can gain analytic access to the finite-size energy spectrum in the one-loop minisuperspace approximation using recently developed methods for Lamé and Heun equations, based on their relations to four-dimensional supersymmetric...

Celestial holography aims to recast flat-space physics in terms of conformal data on the celestial sphere. This invites the use of CFT techniques to analyse observables in flat holography. In this talk I will introduce a Mellin-amplitude representation for celestial correlators, inspired by the Mellin amplitudes for holographic correlators in AdS/CFT. Celestial Mellin amplitudes streamline...

The TTbar deformation is a remarkable example of a solvable irrelevant deformation in two-dimensional quantum field theory. Its extension to higher dimensions is obstructed by the loss of factorisation and the onset of non-locality.
In this talk, I discuss a class of TTbar-like deformations in $d>2$ formulated directly in terms of the stress-energy tensor. I show how these flows naturally...

The Double Copy relations allow one to compute (super-)gravitational scattering amplitudes from (super-)Yang-Mills ones. We explore this paradigm off-shell by attempting the construction of $\mathcal{N}=1$ and $\mathcal{N}=2$ Supergravity Lagrangians using suitably chosen pairs of (super-)Yang-Mills theories as building blocks. Our double-copy fields and gauge symmetries are defined as...
