Impurities Near the Light Cone
Gabriel Cuomo, Simone Giombi, Luigi Tizzano
The lightlike Wilson line cusp underlies the Sudakov double logarithm and is a central ingredient in gauge-theory factorization. We ask what replaces this behavior for general conf…
The two-flavor Schwinger model at 50: Solving Coleman's puzzles
Gabriel Cuomo, Ross Dempsey, Andrei Katsevich +4
In his 1976 paper "More about the massive Schwinger model", Coleman introduced -dimensional Quantum Electrodynamics coupled to two charged massive fermions. By applying Abelia…
Conformal Collider Physics at Large Charge
Gabriel Cuomo, Eren Firat, Filippo Nardi +1
We study energy correlators and other event shapes in states created by operators with large global charge in Conformal Field Theories. Focusing on theories whose large…
The EFT of Large Spin Mesons
Gabriel Cuomo, Sergei Dubovsky, Guzmán Hernández-Chifflet +2
We use effective string theory to study mesons with large spin in large QCD as rotating open strings. In the first part of this work, we formulate a consistent effective…
Quantum vorticity: a not so effective field theory
Gabriel Cuomo, Fanny Eustachon, Eren Firat +2
We provide a comprehensive picture for the formulation of the perfect fluid in the modern effective field theory formalism at both the classical and quantum level. Due to the neces…
Impurities with a cusp: general theory and 3d Ising
Gabriel Cuomo, Yin-Chen He, Zohar Komargodski
In CFTs, the partition function of a line defect with a cusp depends logarithmically on the size of the line with an angle-dependent coefficient: the cusp anomalous dimension. In t…
Phases of Wilson Lines: Conformality and Screening
Ofer Aharony, Gabriel Cuomo, Zohar Komargodski +2
We study the rich dynamics resulting from introducing static charged particles (Wilson lines) in 2+1 and 3+1 dimensional gauge theories. Depending on the charges of the external pa…
Spontaneous symmetry breaking on surface defects
Gabriel Cuomo, Shuyu Zhang
Coleman's theorem states that continuous internal symmetries cannot be spontaneously broken in two-dimensional quantum field theories (QFTs). In this work we consider surface (i.e.…
Phases of Wilson Lines in Conformal Field Theories
Ofer Aharony, Gabriel Cuomo, Zohar Komargodski +2
We study the low-energy limit of Wilson lines (charged impurities) in conformal gauge theories in 2+1 and 3+1 dimensions. As a function of the representation of the Wilson line, ce…
Giant Vortices and the Regge Limit
Gabriel Cuomo, Zohar Komargodski
In recent years it has been shown that strongly coupled systems become analytically tractable in the regime of large quantum numbers, such as large spin or large charge. The effect…
Spin Impurities, Wilson Lines and Semiclassics
Gabriel Cuomo, Zohar Komargodski, Márk Mezei +1
We consider line defects with large quantum numbers in conformal field theories. First, we consider spin impurities, both for a free scalar triplet and in the Wilson-Fisher …
Localized magnetic field in the model
Gabriel Cuomo, Zohar Komargodski, Márk Mezei
We consider the critical model in the presence of an external magnetic field localized in space. This setup can potentially be realized in quantum simulators and in some liq…
Boundary Conformal Field Theory at Large Charge
Gabriel Cuomo, Márk Mezei, Avia Raviv-Moshe
We study operators with large internal charge in boundary conformal field theories (BCFTs) with internal symmetries. Using the state-operator correspondence and the existence of a…
Renormalization Group Flows on Line Defects
Gabriel Cuomo, Zohar Komargodski, Avia Raviv-Moshe
We consider line defects in d-dimensional Conformal Field Theories (CFTs). The ambient CFT places nontrivial constraints on Renormalization Group (RG) flows on such line defects. W…
The OPE meets semiclassics
Gabriel Cuomo
We show that the correlator of three large charge operators with minimal scaling dimension can be computed semiclassically in CFTs with a symmetry for arbitrary fixed values…
Large Charge Sector of 3d Parity-Violating CFTs
Gabriel Cuomo, Luca V. Delacretaz, Umang Mehta
Certain CFTs with a global symmetry become superfluids when coupled to a chemical potential. When this happens, a Goldstone effective field theory controls the spectrum and…
A note on the large charge expansion in 4d CFT
Gabriel Cuomo
In this letter, we discuss certain universal predictions of the large charge expansion in conformal field theories with symmetry, mainly focusing on four-dimensional theorie…
Gapped Goldstones at the cut-off scale: a non-relativistic EFT
Gabriel Cuomo, Angelo Esposito, Emanuele Gendy +3
At finite density, the spontaneous breakdown of an internal non-Abelian symmetry dictates, along with gapless modes, modes whose gap is fixed by the algebra and proportional to the…

Superfluids, vortices and spinning charged operators in 4d CFT

We include vortices in the superfluid EFT for four dimensional CFTs at large global charge. Using the state-operator correspondence, vortices are mapped to charged operators with l…
Rotating superfluids and spinning charged operators in conformal field theory
Gabriel Cuomo, Anton de la Fuente, Alexander Monin +2
We calculate the scaling dimensions of operators with large global charge and spin in 2+1 dimensional conformal field theories. By the state-operator correspondence, these operator…
