Exponentially fast dynamics in the Fock space of chaotic man y-body systems.
We demonstrate analytically and numerically that in isolated quantum systems of many interacting particles, the number of states participating in the evolution after a quench increases exponentially in time, provided the ...
Thouless and Relaxation Time Scales in Many-Body Quantum Systems.
Studies of the dynamics of isolated interacting many-body quantum systems are at the forefront of experimental and theoretical physics. A major open question is the identification of the time scales involved in the ...
