Speed limits and locality in many-body quantum dynamics

CFA Chen, A Lucas, C Yin - Reports on Progress in Physics, 2023 - iopscience.iop.org
We review the mathematical speed limits on quantum information processing in many-body
systems. After the proof of the Lieb–Robinson Theorem in 1972, the past two decades have …

Quantum quenches in 1+ 1 dimensional conformal field theories

P Calabrese, J Cardy - Journal of Statistical Mechanics: Theory …, 2016 - iopscience.iop.org
We review the imaginary time path integral approach to the quench dynamics of conformal
field theories. We show how this technique can be applied to the determination of the time …

Real-time confinement following a quantum quench to a non-integrable model

M Kormos, M Collura, G Takács, P Calabrese - Nature Physics, 2017 - nature.com
Quarks cannot be observed as free particles in nature because they are confined into
baryons and mesons, as a result of the fact that the strong interaction between them …

Real Time Dynamics and Confinement in the Schwinger-Weyl lattice model for 1+1 QED

We explore the dynamics of artificial one-and two-dimensional Ising-like quantum
antiferromagnets with different lattice geometries by using a Rydberg quantum simulator of …

Emergence of coherence and the dynamics of quantum phase transitions

S Braun, M Friesdorf, SS Hodgman… - Proceedings of the …, 2015 - National Acad Sciences
The dynamics of quantum phase transitions pose one of the most challenging problems in
modern many-body physics. Here, we study a prototypical example in a clean and well …

“Light-cone” dynamics after quantum quenches in spin chains

L Bonnes, FHL Essler, AM Läuchli - Physical review letters, 2014 - APS
Signal propagation in the nonequilibrium evolution after quantum quenches has recently
