Quantum phase transition and universal dynamics in the Rabi model

MJ Hwang, R Puebla, MB Plenio - Physical review letters, 2015 - APS
We consider the Rabi Hamiltonian, which exhibits a quantum phase transition (QPT) despite
consisting only of a single-mode cavity field and a two-level atom. We prove QPT by deriving …

Quantum simulation of frustrated Ising spins with trapped ions

K Kim, MS Chang, S Korenblit, R Islam, EE Edwards… - Nature, 2010 - nature.com
A network is frustrated when competing interactions between nodes prevent each bond from
being satisfied. This compromise is central to the behaviour of many complex systems, from …

Dynamics of a quantum phase transition and relaxation to a steady state

J Dziarmaga - Advances in Physics, 2010 - Taylor & Francis
We review recent theoretical work on two closely related issues: excitation of an isolated
quantum condensed matter system driven adiabatically across a continuous quantum phase …

Programmable quantum simulations of spin systems with trapped ions

C Monroe, WC Campbell, LM Duan, ZX Gong… - Reviews of Modern …, 2021 - APS
Laser-cooled and trapped atomic ions form an ideal standard for the simulation of interacting
quantum spin models. Effective spins are represented by appropriate internal energy levels …
