On anomalies and gauging of U(1) non-invertible symmetries in 4d QED
Avner Karasik
In this work we propose a way to promote the anomalous axial U(1) transformations to exact non-invertible U(1) symmetries. We discuss the procedure of coupling the non-invertible s…
Chiral Gauge Dynamics: Candidates for Non-Supersymmetric Dualities
Avner Karasik, Kaan Önder, David Tong
We study the dynamics of chiral SU(N) gauge theories. These contain Weyl fermions in the symmetric or anti-symmetric representation of the gauge group, together with further fermio…
Anomalies for anomalous symmetries
Avner Karasik
4d gauge theories with massless fermions typically have axial U(1) transformations that suffer from the ABJ anomaly. One can modify the theory of interest by adding more fields in…
On Discrete Anomalies in Chiral Gauge Theories
Philip Boyle Smith, Avner Karasik, Nakarin Lohitsiri +1
We study two well-known chiral gauge theories with fermions in the symmetric, anti-symmetric and fundamental representations. We give a detailed description of the global s…
Vector dominance, one flavored baryons, and QCD domain walls from the "hidden" Wess-Zumino term
Avner Karasik
We further explore a recent proposal that the vector mesons in QCD have a special role as Chern-Simons fields on various QCD objects such as domain walls and the one flavored baryo…
Skyrmions, Quantum Hall Droplets, and one current to rule them all
Avner Karasik
We introduce a novel Skyrme-like conserved current in the effective theory of pions and vector mesons based on the idea of hidden local symmetry. The associated charge is equivalen…
The Bi-Fundamental Gauge Theory in 3+1 Dimensions: The Vacuum Structure and a Cascade
Avner Karasik, Zohar Komargodski
We study the phases of the SU(N1)X SU(N2) gauge theory with a bi-fundamental fermion in 3+1 dimensions. We show that the discrete anomalies and Berry phases associated to the one-f…
Vortex-strings in N=2 quiver X U(1) theories
Avner Karasik
We study half-BPS vortex-strings in four dimensional N=2 supersymmetric quiver theories with gauge group SU(N)^n X U(1). The matter content of the quiver can be represented by what…
Vortex-Strings in N=2 SQCD and Bulk-String Decoupling
Efrat Gerchkovitz, Avner Karasik
We study vortex-strings in four-dimensional N=2 supersymmetric SU(Nc)xU(1) gauge theories with Nf hypermultiplets in the fundamental representation of SU(Nc) and general U(1) charg…
New Vortex-String Worldsheet Theories from Supersymmetric Localization
Efrat Gerchkovitz, Avner Karasik
We use supersymmetric localization techniques to study the low-energy dynamics of BPS vortex-strings in four-dimensional N=2 theories. We focus on theories with SU(Nc)xU(1) gauge g…
Correlation Functions of Coulomb Branch Operators
Efrat Gerchkovitz, Jaume Gomis, Nafiz Ishtiaque +3
We consider the correlation functions of Coulomb branch operators in four-dimensional N=2 Superconformal Field Theories (SCFTs) involving exactly one anti-chiral operator. These ex…
Supersymmetric Field Theories on AdS_p x S^q
Ofer Aharony, Micha Berkooz, Avner Karasik +1
In this paper we study supersymmetric field theories on an AdS_p x S^q space-time that preserves their full supersymmetry. This is an interesting example of supersymmetry on a non-…
