Scale-Covariant Holography
Nikolay Bobev, Pieter Bomans, Fridrik Freyr Gautason
We explore a vast landscape of scale-covariant string backgrounds that arise from the backreaction of D-branes. In a convenient Weyl frame the metric has an AdS factor and the d…
Unravelling the Holomorphic Twist II: Anomalies and Extended Supersymmetry
Pieter Bomans, Niklas Garner, Brian R. Williams +1
Twists of four-dimensional supersymmetric quantum field theories (SQFTs) isolate protected sectors with rich algebraic structures. We develop a unified framework for analyzing symm…
Spherical Branes and the BMN Matrix Quantum Mechanics
Nikolay Bobev, Pieter Bomans, Fridrik Freyr Gautason
We study the maximally supersymmetric Yang-Mills theory on using supersymmetric localisation and holography. We argue that the analytic continuation in dimension to yie…
Holographic Generalised Gukov-Witten Defects
Pieter Bomans, Lorenzo Tranchedone
Spindle and disc solutions have received significant attention in recent literature. However, it is not entirely clear what these supergravity solutions represent in the dual SCFT.…
Wilson Loops and Spherical Branes
Davide Astesiano, Pieter Bomans, Fridrik Freyr Gautason +2
We study 1/2-BPS Wilson loop operators in maximally supersymmetric Yang-Mills theory on -dimensional spheres. Their vacuum expectation values can be computed at large throug…
On the Class Origin of Spindle Solutions
Pieter Bomans, Christopher Couzens
We analyse the backreacted geometry corresponding to a stack of M5-branes wrapped on a spindle, with a view towards precision tests of the dual superconformal fie…
Unravelling the Holomorphic Twist: Central Charges
Pieter Bomans, Jingxiang Wu
The holomorphic twist provides a powerful framework to study minimally protected sectors in supersymmetric quantum field theories. We investigate the algebraic structure underlying…
Symmetry Breaking and Consistent Truncations from M5-branes Wrapping a Disc
Pieter Bomans, Christopher Couzens, Yein Lee +1
We construct new supersymmetric solutions corresponding to M5-branes wrapped on a topological disc by turning on additional scalars in the background. The presence of such scalar f…
One-Dimensional Sectors From the Squashed Three-Sphere
Pieter Bomans, Silviu Pufu
Three-dimensional superconformal field theories contain 1d topological sectors consisting of twisted linear combinations of half-BPS local operators that can be i…
Spin Structures and AdS Holography
Nikolay Bobev, Pieter Bomans
We study the importance of spin structures as defining data for 11d supergravity backgrounds of the form AdS with a free orbifold action. For a generic c…
Bubble instability of mIIA on
Pieter Bomans, Davide Cassani, Giuseppe Dibitetto +1
We consider compactifications of massive IIA supergravity on a six-sphere. This setup is known to give rise to non-supersymmetric AdS vacua preserving SO as well as G…
Marginal deformations from type IIA supergravity
Nikolay Bobev, Pieter Bomans, Fridrik Freyr Gautason +1
We study marginal deformations of a class of three-dimensional SCFTs that admit a holographic dual description in massive type IIA supergravity. We compute the dime…
Comments on chiral algebras and -deformations
Nikolay Bobev, Pieter Bomans, Fridrik Freyr Gautason
Every six-dimensional SCFT on contains a set of protected operators whose correlation functions are controlled by a two-dimensional chiral algebr…
Wrapped Branes and Punctured Horizons
Nikolay Bobev, Pieter Bomans, Fridrik Freyr Gautason
Large classes of AdS supergravity backgrounds describing the IR dynamics of -branes wrapped on a Riemann surface are determined by a solution to the Liouville equation. The…
Supersymmetric Yang-Mills, Spherical Branes, and Precision Holography
Nikolay Bobev, Pieter Bomans, Fridrik Freyr Gautason +2
Using supersymmetric localization we compute the free energy and BPS Wilson loop vacuum expectation values for planar maximally supersymmetric Yang-Mills theory on in the str…
Spherical Branes
Nikolay Bobev, Pieter Bomans, Fridrik Freyr Gautason
We construct new solutions of ten-dimensional supergravity with sixteen supercharges which describe the backreaction of D-branes with spherical worldvolume. These solutions are…
