Colour-Twist Operators I: Spectrum and Wave Functions
Andrea Cavaglia, David Grabner, Nikolay Gromov +1
We introduce a new class of operators in any theory with a 't Hooft large- limit that we call colour-twist operators. They are defined by twisting the colour-trace with a global…

Excited States of One-Dimensional Defect CFTs from the Quantum Spectral Curve
David Grabner, Nikolay Gromov, Julius Julius
We study the anomalous dimension of the cusped Maldacena-Wilson line in planar Yang-Mills theory with scalar insertions using the Quantum Spectral Curve (QSC) met…

Strongly γ-deformed N=4 SYM as an integrable CFT
David Grabner, Nikolay Gromov, Vladimir Kazakov +1
We demonstrate by explicit multi-loop calculation that γ-deformed planar N=4 SYM, supplemented with a set of double-trace counter-terms, has two nontrivial fixed points in the rece…
