Ising the way into de Sitter
Giovanni Galati, Stathis Vitouladitis
We study the two-dimensional Ising model deformed by the relevant thermal operator and placed on de Sitter (dS) spacetime. Despite being strongly interacting in its original formul…
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…
Lattice Realizations of Flat Gauging and T-duality Defects at Any Radius
Riccardo Argurio, Giovanni Galati, Nathan Godechal
We analyze non-invertible topological interfaces and defects in the two-dimensional compact boson, focusing on the more exotic ones obtained by gauging continuous symmetries with f…
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…
Symmetries, Universes and Phases of QCD with an Adjoint Dirac Fermion
Jeremias Aguilera Damia, Giovanni Galati, Luigi Tizzano
We study 2d QCD with an adjoint Dirac fermion. Assuming that the IR limit of the massless theory is captured by a WZW coset CFT, we show that this CFT can be decomposed int…
Non-Invertible T-duality at Any Radius via Non-Compact SymTFT
Riccardo Argurio, Andrés Collinucci, Giovanni Galati +2
We extend the construction of the T-duality symmetry for the 2d compact boson to arbitrary values of the radius by including topological manipulations such as gauging continuous sy…
On the Symmetry TFT of Yang-Mills-Chern-Simons theory
Riccardo Argurio, Francesco Benini, Matteo Bertolini +2
Three-dimensional Yang-Mills-Chern-Simons theory has the peculiar property that its one-form symmetry defects have non-trivial braiding, namely they are charged under the same symm…
Exploring duality symmetries, multicriticality and RG flows at
Jeremias Aguilera Damia, Giovanni Galati, Ondrej Hulik +1
In this work, we study the realization of non-invertible duality symmetries along the toroidal branch of the conformal manifold. A systematic procedure to construct symmetry…
Anomalies of non-invertible self-duality symmetries: fractionalization and gauging
Andrea Antinucci, Francesco Benini, Christian Copetti +2
We study anomalies of non-invertible duality symmetries in both 2d and 4d, employing the tool of the Symmetry TFT. In the 2d case we rephrase the known obstruction theory for the T…
Symmetries and topological operators, on average
Andrea Antinucci, Giovanni Galati, Giovanni Rizi +1
We study Ward identities and selection rules for local correlators in disordered theories where a 0-form global symmetry of a QFT is explicitly broken by a random coupling but…
"Zoology" of non-invertible duality defects: the view from class
Andrea Antinucci, Christian Copetti, Giovanni Galati +1
We study generalizations of the non-invertible duality defects present in SU(N) SYM by studying theories with larger duality groups. We focus on 4d $\mathcal{N} =…
The holography of non-invertible self-duality symmetries
Andrea Antinucci, Francesco Benini, Christian Copetti +2
We study how non-invertible self-duality defects arise in theories with a holographic dual. We focus on the paradigmatic example of SYM. The th…
On Continuous 2-Category Symmetries and Yang-Mills Theory
Andrea Antinucci, Giovanni Galati, Giovanni Rizi
We study a 4d gauge theory obtained from a theory by gauging a 0-form symmetry . We show that this theory has a global continuous 2-catego…
Cancellation of IR Divergences in 3d Abelian Gauge Theories
Giovanni Galati, Marco Serone
Three dimensional abelian gauge theories classically in a Coulomb phase are affected by IR divergences even when the matter fields are all massive. Using generalizations of Ward-Ta…
