Computing Nonequilibrium Transport from Short-Time Transients: From Lorentz Gas to Heat Conduction in One Dimensional Chains
Davide Carbone, Vincenzo Di Florio, Stefano Lepri +1
We test the Transient Time Correlation Function (TTCF) method to compute nonequilibrium transport coefficients, highlighting its conceptual and practical difference from the standa…

Dephasing-induced relaxation in tight-binding chains with linear and nonlinear defects
Debraj Das, Andrea Gambassi, Stefano Iubini +1
We investigate thermalization in a tight-binding chain with an on-site defect subject to local dephasing noise implemented as random phase kicks. For a single linear defect of stre…

Lax dynamics
Stefano Lepri
A novel approach is proposed to characterize the dynamics of perturbed many-body integrable systems. Focusing on the paradigmatic case of the Toda chain under non-integrable Hamilt…
