The motion of a particle near a horizon of a spherically symmetric static black hole is shown
to possess a universal Lyapunov exponent of chaos bounded by its surface gravity. To …

A bstract We study integrability and non-integrability for marginal deformations of
4d\(\mathcal {N}\)= 2 SCFTs. We estimate various chaos indicators for the bulk theory which …

A bstract In this work we study various aspects of six-dimensional\(\mathcal {N}\)=(1, 0)
SCFTs. We consider the construction of their string duals in Massive IIA and discuss some …

A bstract We show that the string worldsheet theory of Gaiotto-Maldacena holographic duals
to\(\mathcal {N}= 2\) superconformal field theories generically fails to be classically …

A bstract We consider a pulsating string near a non-extremal black p-brane (p= 5 and p= 6)
and investigate the chaos in the corresponding string dynamics by examining the Fast …

A bstract In the framework of six-dimensional conformal field theories with\(\mathcal {N}=\left
(1,\0\right)\) supersymmetry we develop the map between the holographic description, the …

A bstract By using the general framework of affine Gaudin models, we construct a new class
of integrable sigma models. They are defined on a coset of the direct product of N copies of …

A bstract We study the interplay between a particular marginal deformation of\(\mathcal
{N}\)= 4 super Yang-Mills theory, the β deformation, and integrability in the holographic …

We show that the AdS 5× L a, b, c solution in type IIB theory is nonintegrable. To do so, we
consider a string embedding and study its fluctuations which do not admit Liouville …

A bstract We consider a class of 2d σ-models on products of group spaces that provide new
examples of a close connection between integrability and stability under the RG flow. We …
