(Anti-)De Sitter null strings and Carroll-Weyl symmetry
Ulf Lindström, Bo Sundborg
We construct a null string in a novel way by lifting the standard tensionless string to . Gauging worldsheet scale symmetry introduces terms in the action breaking…
Baryons in vector models and their duals in higher spin theory
Bo Sundborg
Black shells, a kind of black hole mimickers, are identified thermodynamically as bulk duals of baryon operators in vector models, indicating that such objects are essential for th…
Classifying large N limits of multiscalar theories by algebra
Nadia Flodgren, Bo Sundborg
We develop a new approach to RG flows and show that one-loop flows in multiscalar theories can be described by commutative but non-associative algebras. As an example related to $D…
One-loop algebras and fixed flow trajectories in adjoint multi-scalar gauge theory
Nadia Flodgren, Bo Sundborg
We study the one loop renormalisation of 4d Yang-Mills theory with adjoint representation scalar multiplets related by symmetry. General are of field theoret…
One-loop fixed points of adjoint multi-scalar gauge theory in four dimensions
Nadia Flodgren, Bo Sundborg
We determine complete one-loop beta functions of the multi-scalar four-point couplings in four-dimensional gauge theories with adjoint scalar multiplets. For adjoints s…
Tidal excitation as mixing in thermal CFT
Julius Engelsöy, Bo Sundborg
We use mixed correlators in thermal CFT as clean probes of the strong gravity effects in their holographic duals. The dual interpretation of mixing is an inelastic conversion of on…
