Line Operators of Gauge Theories on Non-Spin Manifolds

J. P. Ang, Konstantinos Roumpedakis, Sahand Seifnashri

We study four-dimensional gauge theories on oriented and non-spin spacetime manifolds. On such manifolds, each line operator arises only either as a boson or a fermion. Based on ph…

$Ad S_{3} \times S^{3}$ Tree-Level Correlators: Hidden Six-Dimensional Conformal Symmetry

Leonardo Rastelli, Konstantinos Roumpedakis, Xinan Zhou

We revisit the calculation of holographic correlators in $A d S_{3}$ . We develop new methods to evaluate exchange Witten diagrams, resolving some technical difficulties that prevent a…

3D Dualities and Supersymmetry Enhancement from Domain Walls

Martin Roček, Konstantinos Roumpedakis, Sahand Seifnashri

We test recently proposed IR dualities and supersymmetry enhancement by studying the supersymmetry on domain walls. In the $S U (3)$ Wess-Zumino model studied in arXiv:1804.02018 and…

Comments on the $S_{N}$ orbifold CFT in the large $N$ -limit

Konstantinos Roumpedakis

We elaborate on various aspects of the conformal field theory of the symmetric orbifold. We collect various results that have appeared in the literature, and we present a coherent…
