Aspects of supersymmetric gauge theories and conformal field theories in five and three dimensions by Eckhard, J

The global form of flavor symmetries and 2-group symmetries in 5d SCFTs by Apruzzi, F, Schäfer-Nameki, S, Bhardwaj, L, Oh, J

Box graphs and resolutions II: From Coulomb phases to fiber faces by Braun, A, Schäfer-Nameki, S

“…Box graphs, or equivalently Coulomb phases of three-dimensional N= 2 supersymmetric gauge theories with matter, give a succinct, comprehensive and elegant characterization of crepant resolutions of singular elliptically fibered varieties. …”

Non-invertible symmetry webs by Bhardwaj, L, Bottini, LE, Schäfer-Nameki, S, Tiwari, A

“…The highlight of this analysis is the complete categorical symmetry web, including non-invertible symmetries, for 3d pure gauge theories with orthogonal gauge groups and its extension to arbitrary dimensions.…”

Higgs bundles for M-theory on G2-manifolds by Braun, A, Cizel, S, Hübner, M, Schäfer-Nameki, S

“…M-theory compactified on G2-holonomy manifolds results in 4d N = 1 supersymmetric gauge theories coupled to gravity. In this paper we focus on the gauge sector of such compactifications by studying the Higgs bundle obtained from a partially twisted 7d super Yang-Mills theory on a supersymmetric three-cycle M3. …”

F-theory and 2d (0, 2) theories by Schäfer-Nameki, S, Weigand, T

“…F-theory compactified on singular, elliptically fibered Calabi-Yau five-folds gives rise to two-dimensional gauge theories preserving N = (0, 2) supersymmetry. In this paper we initiate the study of such compactifications and determine the dictionary between the geometric data of the elliptic fibration and the 2d gauge theory such as the matter content in terms of (0, 2) superfields and their supersymmetric couplings. …”

Non-invertible higher-categorical symmetries by Bhardwaj, L, Bottini, L, Schäfer-Nameki, S, Tiwari, A

“…We illustrate this procedure by constructing non-invertible 2-categorical symmetries in 4d gauge theories and non-invertible 3-categorical symmetries in 5d and 6d theories. …”

Symmetry TFTs for 3d QFTs from M-theory by van Beest, M, Gould, DSW, Schäfer-Nameki, S, Wang, YN

“…Secondly, we compute the SymTFT for 3d N = 2 quiver gauge theories whose holographic duals are based on Sasaki-Einstein 7-manifolds of type Y7 = Yp,k(CP2). …”

Universal non-invertible symmetries by Bhardwaj, L, Schäfer-Nameki, S, Wu, J

“…We describe how our results can be applied to compute non-invertible symmetries of various classes of gauge theories with continuous disconnected gauge groups in various spacetime dimensions. …”

M5-branes on S2 × M4: Nahm’s equations and 4d topological sigma-models by Assel, B, Schäfer-Nameki, S, Wong, J

“…We study the 6d N = (0, 2) superconformal field theory, which describes multiple M5-branes, on the product space S2 × M4, and suggest a correspondence between a 2d N = (0, 2) half-twisted gauge theory on S2 and a topological sigma-model on the four-manifold M4. …”
