We consider circular Wilson loops in a defect version of N=4 super-Yang-Mills theory
which is dual to the D5-D3 brane system. When the loops are parallel to the defect, we
can construct both BPS and non-BPS operators. At strong 't Hooft coupling we observe,
in the non-BPS case, a Gross-Ooguri-like phase transition in the dual gravitational theory:
the familiar disk solution dominates when the...

Seiberg duality is an infrared equivalence of two 4d, N=1 gauge theories first proposed by Seiberg in 1994. More recently a triality relating 2d, (0,2) theories and a quadrality relating 0d, N=1 matrix models have been discovered, both of these can be viewed as generalizations of Seiberg duality to lower dimensions. We illustrate these dualities with the help of simple examples arising on...

Infra-red dualities are interesting phenomena that may characterize the low energy behaviour of quantum field theories. One challenging question is whether it is possible to find some organizing principle that allows us to derive the currently known dualities in low dimensions from some mother dualities in higher dimensions upon dimensional reduction. When the theory is supersymmetric, this...
