Real-space renormalization-group study of decoherence and revival following a sudden quench in a finite system

Felipe D. Picoli, Gustavo Diniz, Luiz N. Oliveira

The paper studies how a quantum impurity (spinless resonant level) loses and regains coherence after a sudden change in its coupling to a metal, using real‑space renormalization‑gr…
