On the Ising/tricritical-Ising interface: From symmetry to Rydberg atoms
António Antunes, Junchen Rong
We consider interfaces between critical spin-chains in different universality classes, described in the continuum limit by defect/interface conformal field theory (DCFT/ICFT). We f…
Ising surface defects can get dirty
António Antunes, Apratim Kaviraj, Baishali Roy
Real critical systems, such as uniaxial ferromagnets in the 3d Ising universality class, are constrained by boundaries and subject to random couplings. We consider the Wilson-Fishe…
Five points for the Polyakov Bootstrap
António Antunes, Sebastian Harris, Apratim Kaviraj
Higher-point correlation functions encode the data of infinitely many 4-point correlators in conformal field theory (CFT). In this paper, we develop new tools to efficiently extrac…
A bootstrap study of minimal model deformations
António Antunes, Edoardo Lauria, Balt C. van Rees
For QFTs in AdS the boundary correlation functions remain conformal even if the bulk theory has a scale. This allows one to constrain RG flows with numerical conformal bootstrap me…
Lining up a Positive Semi-Definite Six-Point Bootstrap
António Antunes, Sebastian Harris, Apratim Kaviraj +1
In this work we initiate a positive semi-definite numerical bootstrap program for multi-point correlators. Considering six-point functions of operators on a line we reformulate the…
