[HTML][HTML] RG flow of integrable E-models
F Hassler - Physics Letters B, 2021 - Elsevier
We compute the one-and two-loop RG flow of integrable σ-models with Poisson-Lie
symmetry. They are characterised by a twist function with 2N simple poles/zeros and a …

Duality invariant string beta functions at two loops
A bstract We compute, for cosmological backgrounds, the O (d, d; ℝ) invariant beta functions
for the sigma model of the bosonic string at two loops. This yields an independent first …

Full S-matrices and Witten diagrams with (relative) L-infinity algebras
The $ L_\infty $-algebra approach to scattering amplitudes elegantly describes the nontrivial
part of the $ S $-matrix but fails to take into account the trivial part. We argue that the trivial …

Dimensional reduction of Courant sigma models and Lie theory of Poisson groupoids
A Cabrera, M Cueca - Letters in Mathematical Physics, 2022 - Springer
We show that the 2d Poisson Sigma Model on a Poisson groupoid arises as an effective
theory of the 3d Courant Sigma Model associated with the double of the underlying Lie …

Quantizing derived mapping stacks
RE Grady - International Journal of Modern Physics A, 2020 - World Scientific
In this paper we discuss several topological and geometric invariants obtained by quantizing
σ-models. More precisely, we do not quantize the entire mapping stack of fields, but rather …

Geometric approaches to quantum fields and strings at strong couplings
T Rochais - 2021 - search.proquest.com
Geometric structures and dualities arise naturally in quantum field theories and string theory.
In fact, these tools become very useful when studying strong coupling effects, where …
