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…

A new 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…

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…
