A bstract We show that an extremely generic class of two-dimensional conformal field
theories (CFTs) contains a sector described by the Schwarzian theory. This applies to …

We probe the contraction from 2 d relativistic CFTs to theories with Bondi-Metzner-Sachs
(BMS) symmetries, or equivalently conformal Carroll symmetries, using diagnostics of …

The harmonic oscillator is the paragon of physical models; conceptually and computationally
simple, yet rich enough to teach us about physics on scales that span classical mechanics to …

Recently, in various theoretical works, path-breaking progress has been made in recovering
the well-known page curve of an evaporating black hole with quantum extremal islands …

A bstract Pole-skip** is a recently discovered signature of many-body quantum chaos in
collective energy dynamics. It establishes a precise connection between resummed, all …

A bstract We construct a model of Pauli spin operators with all-to-all 4-local interactions by
replacing Majorana fermions in the SYK model with spin operators. Equivalently, we replace …

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

We propose a new type of locally interacting quantum circuits—quantum cellular automata—
that are generated by unitary interactions round-a-face (IRF). Specifically, we discuss a set …

A bstract We investigate circuit complexity to characterize chaos in multiparticle quantum
systems. In the process, we take a stride to analyze open quantum systems by using …

We suggest a new indicator of quantum chaos based on the logarithmic out-of-time-order
correlator. On the one hand, this indicator correctly reproduces the average classical …
