Overlaps and Fermionic Dualities for Integrable Super Spin Chains
Charlotte Kristjansen, Dennis Müller, Konstantin Zarembo
The psu(2,2|4) integrable super spin chain underlying the AdS/CFT correspondence has integrable boundary states which describe set-ups where k D3-branes get dissolved in a probe D5…

Integrable boundary states in D3-D5 dCFT: beyond scalars
Charlotte Kristjansen, Dennis Müller, Konstantin Zarembo
A D3-D5 intersection gives rise to a defect CFT, wherein the rank of the gauge group jumps by k units across a domain wall. The one-point functions of local operators in this set-u…

Yangian Bootstrap for Conformal Feynman Integrals
Florian Loebbert, Dennis Müller, Hagen Münkler
We explore the idea to bootstrap Feynman integrals using integrability. In particular, we put the recently discovered Yangian symmetry of conformal Feynman integrals to work. As a…
