Large deviations in quantum dynamics and complexity
Xiangyu Cao, Jorge Kurchan
We study three definitions of large deviation in many-body quantum dynamics: (i) via the full distribution of an extensive observable, (ii) via the distribution of measurement outc…
Entropy of Liquids and Glasses from Recurring Structural Patterns
Nina Javerzat, Gerhard Jung, Jorge Kurchan +1
We compute the low-temperature configurational entropy of a two-dimensional supercooled liquid. Our method, based on a higher-dimensional version of the Grassberger--Procaccia algo…
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…
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…
