't Hooft loops and integrability
Charlotte Kristjansen, Konstantin Zarembo
We consider the defect CFT defined by a 't Hooft line embedded in N=4 super Yang-Mills theory. By explicitly quantizing around the given background we exactly reproduce a predictio…
Integrable domain walls in ABJM theory
Charlotte Kristjansen, Dinh-Long Vu, Konstantin Zarembo
One-point functions of local operators are studied, at weak and strong coupling, for the ABJM theory in the presence of a 1/2 BPS domain wall. In the underlying quantum spin chain…
Duality Relations for Overlaps of Integrable Boundary States in AdS/dCFT
Charlotte Kristjansen, Dennis Müller, Konstantin Zarembo
The encoding of all possible sets of Bethe equations for a spin chain with SU(N|M) symmetry into a QQ-system calls for an expression of spin chain overlaps entirely in terms of Q-f…
String integrability of defect CFT and dynamical reflection matrices
Georgios Linardopoulos, Konstantin Zarembo
The D3-D5 probe-brane system is holographically dual to a defect CFT which is known to be integrable. The evidence comes mainly from the study of correlation functions at weak coup…
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…
