Effective strings and particles interacting in 3D: the Ising model
J. M. Viana Parente Lopes, José Matos, Joao Penedones
We study how a fluctuating domain wall in three dimensions modifies bulk observables in a gapped phase. We introduce an effective interaction between the wall and the lightest bulk…
QFT as a set of ODEs
Manuel Loparco, Grégoire Mathys, Joao Penedones +2
Correlation functions of local operators in Quantum Field Theory (QFT) on hyperbolic space can be fully characterized by the set of QFT data $\lbrace Δ_i,C_{ijk},b^{\hat{\mathcal{O…
Locality constraints in AdS without parity
Manuel Loparco, Grégoire Mathys, João Penedones +2
We study bulk locality constraints in quantum field theories in AdS. The known derivation of locality sum rules in AdS does not apply for due to the different sin…
Effective string theory on a torus: the 3d Ising domain wall
David Lima, J. M. Viana Parente Lopes, Jose Matos +1
We use effective string theory (EST) to describe a toroidal 2d domain wall embedded in a 3d torus. In particular, we compute the free energy of the domain wall in an expansion in i…
What is a photon in de Sitter spacetime?
Manuel Loparco, Joao Penedones, Yannis Ulrich
The states of a single photon in four-dimensional de Sitter (dS) spacetime form a Unitary Irreducible Representation (UIR) of SO(1,4), which we call the photon UIR. While in flat s…
Einstein gravity from a matrix integral -- Part II
Shota Komatsu, Adrien Martina, Joao Penedones +2
Using supersymmetric localization, we compute the partition function and some protected correlators of the polarized IKKT matrix model. Surprisingly, we find that the original IKKT…
