У оквиру семинара Института за физику у Београду, у среду, 9. октобра 2024. године у 12 часова путем Zoom платформе, Банашри Баишја (Индијски институт за технологију Гувахати) одржаће предавање:
An equivalence of three butterflies in Lifshitz background
САЖЕТАК:
In this talk I will talk about two salient chaotic features, namely Lyapunov exponent and butterfly velocity, in the context of an asymptotically Lifshitz black hole background with an arbitrary critical exponent. These features are computed using three methods: entanglement wedge method, out-of-time-ordered correlator computation and pole-skipping. I will present a comparative study of the features mentioned above where all of these methods yield similar results for the butterfly velocity and the Lyapunov exponent. This establishes an equivalence between all three methods for probing chaos in the chosen gravity background. Furthermore, I will talk about chaos at the classical level by computing the eikonal phase and Lyapunov exponent from the bulk gravity. These quantities emerge as nontrivial functions of the anisotropy index.
