Black hole scrambling from hydrodynamics

S Grozdanov, K Schalm, V Scopelliti - Physical Review Letters, 2018 - APS
We argue that the gravitational shock wave computation used to extract the scrambling rate
in strongly coupled quantum theories with a holographic dual is directly related to probing …

dilaton gravity from reductions of some nonrelativistic theories

KS Kolekar, K Narayan - Physical Review D, 2018 - APS
We study dilaton-gravity theories in two dimensions obtained by dimensional reduction of
higher-dimensional nonrelativistic theories. Focusing on certain families of extremal charged …

[HTML][HTML] Collision of particles and energy extraction in hyperscaling violation background

J Sadeghi, B Pourhassan, S Soroushfar, R Toorandaz - Nuclear Physics B, 2023 - Elsevier
In this paper, we investigate particle collision near the charged black hole with hyperscaling
violating factor under different conditions on mass, charge and θ parameters. In that case …

A Chattopadhyay, D Mukherjee - The European Physical Journal C, 2023 - Springer
We study the flow equations of the shear response functions for hyperscaling violating
Lifshitz (hvLif) theories, with Lifshitz and hyperscaling violating exponents z and\(\theta\) …

[PDF][PDF] Aspects of holography: mainly nAdS2 holography from dimensional reduction and non-relativistic holography for hyperscaling violating Lifshtiz theories

KS Kolekar - 2020 - libarchive.cmi.ac.in
The Bekenstein-Hawking entropy formula [1, 2] states that the entropy of a black hole is
proportional to area of the horizon rather than its volume. This motivated the holographic …

[PDF][PDF] Hydrodynamics and the quantum butterfly effect in black holes and large N

V Scopelliti - JHEP, 2014 - scholarlypublications …
How does a closed quantum system thermalize? And why do black holes emit thermal
radiation? Over the last decades, these two seemingly unrelated questions have attracted …
