Planckian dissipation from classical hydrodynamics
Laura Foini, Jorge Kurchan, Silvia Pappalardi
In this work we ask what the self-consistency of a classical hydrodynamic description imposes on a quantum system. The quantum fluctuation-dissipation theorem, when read in the tim…
Refinements of the Eigenstate Thermalization Hypothesis under Local Rotational Invariance via Free Probability
Elisa Vallini, Laura Foini, Silvia Pappalardi
The Eigenstate Thermalization Hypothesis (ETH) was developed as a framework for understanding how the principles of statistical mechanics emerge in the long-time limit of isolated…
Quenched properties of the Spectral Form Factor
Dimitrios Charamis, Manas Kulkarni, Jorge Kurchan +1
The Spectral Form Factor (SFF) is defined as the modulus squared of the partition function in complex temperature for hermitian matrices and a suitable generalisation has been give…
Random matrix universality in dynamical correlation functions at late times
Oscar Bouverot-Dupuis, Silvia Pappalardi, Jorge Kurchan +2
We study the behavior of two-time correlation functions at late times for finite system sizes considering observables whose (one-point) average value does not depend on energy. In…
Out-of-equilibrium Eigenstate Thermalization Hypothesis
Laura Foini, Anatoly Dymarsky, Silvia Pappalardi
Understanding how out-of-equilibrium states thermalize under quantum unitary dynamics is an important problem in many-body physics. In this work, we propose a statistical ansatz fo…
Microcanonical windows on quantum operators
Silvia Pappalardi, Laura Foini, Jorge Kurchan
We discuss the construction of a microcanonical projection WOW of a quantum operator O induced by an energy window filter W, its spectrum, and the retrieval of canonical many-time…
