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 …

Colloquium: Quantum annealing and analog quantum computation

A Das, BK Chakrabarti - Reviews of Modern Physics, 2008 - APS
The recent success in quantum annealing, ie, optimization of the cost or energy functions of
complex systems utilizing quantum fluctuations is reviewed here. The concept is introduced …

Scrambling and entanglement spreading in long-range spin chains

S Pappalardi, A Russomanno, B Žunkovič, F Iemini… - Physical Review B, 2018 - APS
We study scrambling in connection with multipartite entanglement dynamics in regular and
chaotic long-range spin chains, characterized by a well-defined semi-classical limit. For …
