Journal Article

We study the discrete chiral- and center-symmetry ’t Hooft anomaly matching in the charge-q two-dimensional Schwinger model. We show that the algebra of the discrete symmetry operators involves a central extension, implying the existence of q vacua,...

Entanglement entropy, dualities, and deconfinement in gauge theories (2018)
Journal Article
Anber, M. M., & Kolligs, B. J. (2018). Entanglement entropy, dualities, and deconfinement in gauge theories. Journal of High Energy Physics, 2018(8), Article 175. https://doi.org/10.1007/jhep08%282018%29175

Computing the entanglement entropy in confining gauge theories is often accompanied by puzzles and ambiguities. In this work we show that compactifying the theory on a small circle S1L evades these difficulties. In particular, we study Yang-Mills the...

Two-flavor adjoint QCD (2018)
Journal Article
Anber, M. M., & Poppitz, E. (2018). Two-flavor adjoint QCD. Physical Review D, 98(3), Article 034026. https://doi.org/10.1103/physrevd.98.034026

We study four-dimensional S U ( 2 ) Yang-Mills theory with two massless adjoint Weyl fermions. When compactified on a spatial circle of size L much smaller than the strong-coupling scale, this theory can be solved by weak-coupling nonperturbative sem... Read More about Two-flavor adjoint QCD.

Large-scale messengers from massive higher spin fields (2018)
Journal Article
Anber, M. M. (2018). Large-scale messengers from massive higher spin fields. Journal of High Energy Physics, 2018(6), Article 154. https://doi.org/10.1007/jhep06%282018%29154

We show that nonperturbative production of massive higher spin fields from vacuum will accompany the generation of non-vanishing macroscopic energy-momentum tensor correlators. This argument is based on the general causal field formalism, which gives... Read More about Large-scale messengers from massive higher spin fields.

New nonperturbative scales and glueballs in confining supersymmetric gauge theories (2018)
Journal Article
Anber, M. M., & Poppitz, E. (2018). New nonperturbative scales and glueballs in confining supersymmetric gauge theories. Journal of High Energy Physics, 2018(3), Article 052. https://doi.org/10.1007/jhep03%282018%29052

We show that new nonperturbative scales exist in four-dimensional N = 1 super-Yang-Mills theory compactified on a circle, with an iterated-exponential dependence on the inverse gauge coupling. The lightest states with the quantum numbers of four-dime... Read More about New nonperturbative scales and glueballs in confining supersymmetric gauge theories.
