I will consider 4d N=4 SYM on real projective space preserving half of supersymmetry and focus on the case where charge conjugation is gauged. The holographic dual of this setup is a Z2 quotient of AdS5xS5 with an O1 orientifold. I will discuss how to use analytic conformal bootstrap techniques to compute all two-point functions of 1/2-BPS operators of arbitrary weights at the leading order in...
Unitarity, causality, and Lorentz invariance of the fundamental theory are very constraining assumptions that are capable of building a link between low-energy EFT and its UV completion through the dispersion relations on scattering amplitudes. In this talk, I will consider the EFT of photons (or any other U(1) gauge field) and compare different approaches to obtain bounds on its Wilson...
In this work, we revisit the approach with the covariant phase space formalism for the asymptotic symmetry analysis in the pure AdS3 gravity. We modify the approach to a version which is exactly in the framework of Noether’s theorem. And the key point in the modification is to take a systematical treatment of the boundary effects. In particular, we start from defining the pure AdS3 gravity in...
We calculate the holographic central charges for general higher curvature gravity theory dual to eight dimensional CFT. To do this, we first elaborate the general form of Weyl anomaly in 8d CFT and find 11 non-trivial linearly independent curvature combinations, one of which is Euler density and the rest are Weyl invariants, including 7 non-differentiated ones and 3 differentiated ones. The...
In the framework of the AdS/CFT correspondence, the Fefferman-Graham (FG) gauge offers a useful way to express asymptotically anti-de Sitter spaces, allowing a clear identification of their boundary structure. Although, it is well-known that in holographic theories bulk diffeomorphisms imply Weyl invariance of the dual field theory, choosing a conformal representative for the boundary metric in...
We consider two types of $T\bar T$ deformed Boundary Conformal Field Theory (BCFT) and propose their holographic duals. The first type, which we refer to as Type A, deforms the boundary of the BCFT using the $T\bar T$ operator. The second type, referred to as Type B, leaves the boundary of the BCFT undeformed. We compute boundary entropy in Type A to show the boundary deformation and compute...
The dynamics of first-order phase transitions in strongly coupled systems are relevant in a variety of systems, from heavy ion collisions to the early universe. Holographic theories can be used to model these systems, with fluctuations usually suppressed. In this case the system can come close to a spinodal point where theory and experiments indicate that the the behaviour should be similar to...
