Ising the way into de Sitter
Giovanni Galati, Stathis Vitouladitis
The paper solves the two‑dimensional Ising model with a thermal deformation on de Sitter spacetime using fermionisation, computes exact cosmological correlators, and compares them…
A Twist on Scattering from Defect Anomalies
Andrea Antinucci, Christian Copetti, Giovanni Galati +1
In the presence of extended defects, familiar incoming particles can scatter into exotic outgoing states created by twist operators. We show that one possible mechanism driving the…
Confining Strings in a Gapless Phase
Jeremias Aguilera Damia, Giovanni Galati, Giovanni Rizi
We consider the dynamics of confined strings embedded in a gapless four-dimensional theory. To this end, we examine finite-tension string-like solutions to the equations of motion…
4d Maxwell on the Edge: Global Aspects of Boundary Conditions and Duality
Adrien Arbalestrier, Riccardo Argurio, Giovanni Galati +1
We revisit Maxwell theory in 4d with a boundary, with particular attention to the global properties of the boundary conditions, both in the free (topological) and interacting (conf…
Defect Conformal Manifolds from Phantom (Non-Invertible) Symmetries
Andrea Antinucci, Christian Copetti, Giovanni Galati +1
We explore a general mechanism that allows (1+1)d CFTs to have interesting interface conformal manifolds even in the absence of any continuous internal symmetry or supersymmetry. T…
Topological Constraints on Defect Dynamics
Andrea Antinucci, Christian Copetti, Giovanni Galati +1
Extended objects (defects) in Quantum Field Theory exhibit rich, nontrivial dynamics describing a variety of physical phenomena. These systems often involve strong coupling at long…
