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…
Temporal structures of the X-ray photoemission problem
F. D. Picoli, G. Diniz, M. P. Lenzarini +2
Theoretical studies of X-ray photoemission from simple metals have traditionally focused on the frequency domain, aiming to reproduce experimental spectra. Here, we investigate the…
Analytical Diagonalization of Fermi Gas-like Hamiltonians using the Sommerfeld-Watson Transformation
G. Diniz, F. D. Picoli, M. P. Lenzarini
The Sommerfeld-Watson transformation is a powerful mathematical technique widely used in physics to simplify summations over discrete quantum numbers by converting them into contou…
Tracking Adiabaticity in Non-Equilibrium Many-Body Systems: The Hard Case of the X-ray Photoemission in Metals
G. Diniz, F. D. Picoli, L. N. Oliveira +1
The level of adiabaticity determines many properties of time-dependent quantum systems. However, a reliable and easy-to-apply criterion to check and track it remains an open questi…
