In ergodic many-body quantum systems, locally encoded quantum information becomes, in
the course of time evolution, inaccessible to local measurements. This concept of …

This tutorial article introduces the physics of quantum information scrambling in quantum
many-body systems. The goals are to understand how to precisely quantify the spreading of …

We present a summary of recent progress and remaining challenges in applying the
methods and ideas of quantum information theory to the study of quantum field theory and …

We study the momentum-space entanglement between the sub-and super-Hubble modes of
a spectator scalar field, with a cubic λ ϕ 3 interaction, in de Sitter space. Momentum-space …

We review recent progress and a number of future directions for applications of effective field
theory methods to condensed matter systems broadly defined. Our emphasis is on areas …

Abstract $ Circuit~ Complexity $, a well known computational technique has recently
become the backbone of the physics community to probe the chaotic behaviour and random …

How fast quantum information scrambles such that it becomes inaccessible by local probes
turns out to be central to various fields. Motivated by recent works on spin systems with …

Quantum information scrambling refers to the loss of local recoverability of quantum
information, which has found widespread attention from high energy physics to quantum …

A bstract We construct worldsheet traversable wormholes by considering the effects of a
double-trace deformation,\(\delta\mathcal {L}\sim h\partial {\phi} _L\partial {\phi} _R\) …

The out-of-time-ordered correlation (OTOC) and entanglement are two physically motivated
and widely used probes of the “scrambling” of quantum information, a phenomenon that has …
