I will present the collaborative work arXiv:2203.17157 with Nadav Drukker and Georgios Sakkas. Defects that break the global symmetry group provide some exactly marginal defect operators, which allow to deform a CFT along the defect conformal manifold, which is the symmetry breaking coset. Its Zamolodchikov metric is expressed as the 2-pt function of the exactly marginal operators and the...
In the present work we address the Thermodynamic Bethe Ansatz and ground state energy of the $ AdS_3 \times S_3 \times T_4 $ model from the associated mirror superstring model in the pure RR background. Independently, we show complete consistency with wrapping interaction formalism and derive generalised Lüscher expression for GSE. We prove that the underlying mirror $ Y $-system becomes...
Due to their importance in both, AdS/CFT-correspondence as well as scattering amplitude research, half-BPS correlators of $\mathcal{N}=4$ SYM have experienced a tremendous amount of study in the past years.\
Especially 4- and higher point correlators are of huge interest given that, via the OPE, etc. they contain a wealth of CFT data, also for more complex operators. Despite their...
We are exploring the application of tools from Conformal Field Theories (CFTs) and (conformal) bootstrap to investigate Thermal CFTs. These theories, despite being non-critical, retain many fundamental structures of zero-temperature CFTs, such as the Operator Product Expansion, and maintain an identical conformal spectrum. However, one-point functions at finite temperature can be non zero and...
In this talk, I will discuss the real-time dynamics of gravitons and photon fluctuations around the AdS-Reissner-Nordstrom black hole and argue that the dynamics of these modes are captured by a set of designer scalars in the background geometry. I will show how it is possible to isolate the phonon mode, momentum, and charge diffusion modes, and identify the combination of currents that...
