28. Axialgravisolitons at infinite corner

Poster

Gravitational solitons (gravisolitons) are particular exact solutions of Einstein field equation in vacuum build on a given background solution. Their interpretation is not yet fully clear but they contain many of the physically relevant solutions low $N$-solitons solutions. However, a systematic study and characterization of gravisolitons solution for every $N$ is lacking and their relevance...

31. Bootstrap of the defect 1/2 BPS Wilson lines in N=4 Chern-Simons-matter theories

Poster

We compute correlation functions of local operator insertions on the 1/2 BPS Wilson lines of N=4 Chern-Simons-matter theories in 3 dimensions. We study the algebra preserved by the defect CFT supported on the line, identify the superdisplacement multiplet and discuss some of its weak-coupling realizations. By employing a superspace description, we present the 4-point functions of the...

32. Bulk-induced D-brane deformations and the string coupling constant

Poster

We use String Field Theory (SFT) techniques to investigate bulk RG flows in two-dimensional (B)CFTs triggered by slightly relevant operators of weight $(1-y,1-y)$, with $y$ small and positive. Specifically, we compute the change in the $g$-function up to the second order in $y$. In Conformal Perturbation Theory, this involves a notoriously difficult two-loop computation. On the other hand, in...

42. Charge (in)stability and superradiance of Topological Stars

Poster

Topological Stars are smooth horizonless static solutions of Einstein-Maxwell theory in 5-d and they represent possible microstate geometries for non-supersymmetric black holes. This poster explores the possibility of instabilities due to the emission of charged quanta under the electric field sourced by the solution - i. e. strings winding around the compact direction - in analogy with the...

30. Defect Induced Heavy Meson Dynamics in the QCD Conformal Window

Poster

Upon introducing a heavy quark in the perturbative regime of the QCD conformal
window we precisely determine the associated heavy meson spectrum and wave
functions in terms of the number of light flavours and mass. We then compute the
conformal Isgur-Wise function which is a central quantity in heavy quark physics.
We further determine the impact of the residual low energy confining...

2. How to uplift three-dimensional maximal supergravities

Poster

The inverse problem of Scherk-Schwarz compactification of M-theory consists in distinguishing which lower dimensional maximal (gauged) supergravities admit a higher dimensional uplift, assuming the Scherk-Schwarz compactification to be the unique way to get back the initial theory. A general procedure is known in solving the uplift problem, for dimensions higher or equal to four, based on the...

39. Large R-charge Limit for Extremal Correlators in D=4 $\mathcal{N}=2$ SCFTs with rank 1

Poster

In this poster we deal with the study of two-point extremal correlators involving the Coulomb branch chiral ring generator of rank 1 $\mathcal{N}=2$ superconformal field theories in a four dimensional spacetime under the large R-charge Limit. We start with three Argyres-Douglas theories, for which recent results in literature show how to compute the aforementioned correlators using the...

36. Localization of the 5D supergravity action and Euclidean saddles for the black hole index

Poster

We investigate equivariant localization of the gravitational on-shell action in odd dimensions, focusing on five-dimensional ungauged supergravity. We analyze the conditions for cancellation of boundary terms, so that the full action integral is given in terms of the odd-dimensional analog of the nuts and bolts of Gibbons-Hawking. We construct asymptotically flat Euclidean supersymmetric...

33. Massive II A flux compactifications with dynamical open strings

Poster

We consider massive type IIA compactifications down to 4 dimensions in presence of O6 planes and D6 branes parallel to them, in order to preserve half-maximal supersymmetry in 4D. The dynamics of open strings living on the spacetime filling branes is taken into account, in the gauged supergravity description, by adding extra vector multiplets and embedding tensor components. The scalar...

38. NUTs, bolts, and spindles

Poster

We construct 1/4-BPS, asymptotically locally hyperbolic Euclidean solutions of $d=4$, $\mathcal{N}=2$ gauged supergravity, describing the total space of orbifold line bundles over a spindle. These $U(1)\times U(1)$-invariant solutions are divided into two classes, corresponding to either the twist or the anti-twist on the spindle-bolt, and generalize the spherical bolts found in...

29. Partition function of Argyres-Douglas theories on the blowup

Poster

Supersymmetric QFTs can be studied at the non-perturbative level because quantum corrections are under control. In particular, for $\mathcal{N}=2$ theories the IR dynamics is encoded in the Seiberg-Witten curve which is naturally related to an integrable system. In presence of a self-dual Omega background the integrable system becomes time-dependent and is given by Painlevé equations. We...

34. Quantum Black Hole Physics form the Event Horizon

Poster

In the realm of quantum gravity theories, predictions suggest deviations from classical black hole solutions. One promising avenue for exploring these deviations is through a model-independent approach that utilizes metric deformations parameterized by physical quantities like proper distance. While this approach preserves the space-time's invariance under coordinate transformations, practical...

41. Spinning correlators in Celestial Holography

Poster

The study of holographic dualities going beyond the traditional AdS/CFT correspondence has seen a strong impulse in recent years, especially in the context of Minkowski space for the so called Celestial Holography program.
Differently from the case of AdS space, whose boundary lies at spatial infinity and possesses a well defined notion of locality and unitary time evolution, the boundary of...

37. Tensor Chiral Gauge Theories: Dynamics, Generalized Symmetries and Natural Anomaly Matching

Poster

The introduction of the concept of generalized symmetries around ten years ago by Seiberg, Kapustin, Gaiotto, Willett and others, has given new inputs in the studies of strongly-coupled theories. In particular, the idea of gauging some 1-form discrete center symmetries such as ${\mathbb{Z}}_N\subset SU(N)$, allows us to formulate a stronger form of the ’t Hooft anomaly matching criteria than in the...

43. Vacuum energy from qubit entropy in quantum field theory

Poster

I will illustrate a new non-conventional description of the vacuum energy in quantum field theory in terms of quantum entropy. I will show how the vacuum energy of a quantum field at zero temperature is proportional to the quantum entropy of the qubit degrees of freedom associated with virtual fluctuations.
