A bstract Chaos and complexity entail an entropic and computational obstruction to describing a system, and thus are intrinsically difficult to characterize. In this paper, we …
A bstract We study the spectral properties of two classes of random matrix models: non- Gaussian RMT with quartic and sextic potentials, and RMT with Gaussian noise. We …
A bstract The SYK model, a quantum mechanical model of N≫ 1 Majorana fermions χ i, with a q-body, random interaction, is a novel realization of holography. It is known that the AdS 2 …

A bstract We examine the question how string theory achieves a sum over bulk geometries with fixed asymptotic boundary conditions. We discuss this problem with the help of the …
A bstract A class of tensor models were recently outlined as potentially calculable examples of holography: their perturbative large-N behavior is similar to the Sachdev-Ye-Kitaev (SYK) …

A bstract We perform a detailed study of perturbations around 2-charge circular fuzz-balls and compare the results with the ones obtained in the case of 'small'BHs. In addition to the …
We develop a new hybrid WKB technique to compute boundary-to-boundary scalar Green functions in asymptotically-AdS backgrounds in which the scalar wave equation is separable …

A bstract We present a complete symmetry classification of the Sachdev-Ye-Kitaev (SYK) model with\(\mathcal {N}\)= 0, 1 and 2 supersymmetry (SUSY) on the basis of the Altland …
A bstract AdS 2 plays an extremely important role in black-hole physics. We construct several infinite families of supergravity solutions that are asymptotically AdS 2 in the UV, and …
