Lecture notes for various courses I have taught can be found here.
My main research interests are in string theory and quantum field theory. Over the last several years I have been studying the AdS/CFT duality beyond the supergravity limit. More specifically, this research is centred on using integrability and localization to find exact results for supersymmetric theories.
Notes on anomalies, elliptic curves and the BS-D conjecture2019-08-13
by: Lü, Yongchao (Uppsala U.) et al.
We consider anomaly cancellation for $SU(N)\times SU(2)\times U(1)$ gauge theories where the left-handed chiral multiplets are in higher $SU(2)$ representations. In particular, if the left-handed quarks and leptons transform under the triplet representation of $SU(2)$ and if the $U(1)$ gauge group is compact then up to an overall scaling there is only one possible nontriv...
Gauge theories on spheres with 16 supercharges and non-constant couplings2018-11-29

We construct a class of theories with 16 supersymmetries on spheres of dimension nine and less. The gauge coupling and mass terms for the scalar fields depend on the polar angle away from the north pole. Assuming finite coupling on the north pole, this leads to zero coupling at the south pole for d > 4 and infinite ...

We compute the perturbative partition functions for gauge theories with eight supersymmetries on spheres of dimension d ≤ 5, proving a conjecture by the second author. We apply similar methods to gauge theories with four supersymmetries on spheres with d ≤ 3. The results are valid for non-integer d as well. We further pr...
