Abstract We investigate the one-loop spectral problem of γ-twisted, planar N $$ \mathcal{N} $$ = 4 Super Yang-Mills theory in the double-scaling limit of infinite, imaginary twist angle and vanishing Yang-Mills coupling constant. This non-unitary mo

Abstract We calculate the leading contributions to the connected two-point functions of protected scalar operators in the defect version of N $$ \mathcal{N} $$ = 4 SYM theory which is dual to the D5-D3 probe-brane system with k units of background ga

We initiate the calculation of quantum corrections to Wilson loops in a class of four-dimensional defect conformal field theories with vacuum expectation values based on N=4 super Yang–Mills theory. Concretely, we consider an infinite straight Wils

In combination with post-selection, weak measurements can lead to surprising results known as anomalous weak values. These lie outside the bounds of the spectrum of the relevant observable, as in the canonical example of measuring the spin of an elec

We investigate the one-loop spectral problem of $\gamma$-twisted, planar $\mathcal{N}$=4 Super Yang-Mills theory in the double-scaling limit of infinite, imaginary twist angle and vanishing Yang-Mills coupling constant. This non-unitary model has rec

Integrability: From Statistical Systems to Gauge Theory
This chapter gives a basic introduction to N 7equals; 4 SYM theory and the integrability of its planar spectral problem as seen from the perspective of a recent development, namely the AdS/dCFT correspondence and the application of integrability to t

We take the first step in extending the integrability approach to one-point functions in AdS/dCFT to higher loop orders. More precisely, we argue that the formula encoding all tree-level one-point functions of SU(2) operators in the defect version of

We build the framework for performing loop computations in the defect version of N=4 super Yang-Mills theory which is dual to the probe D5-D3 brane system with background gauge-field flux. In this dCFT, a codimension-one defect separates two regions
