- Description
- We show that the onset of thermalization in isolated quantum many-body systems is intimately related to the initial states. Initial states that are chaotic with respect to the Hamiltonian dictating the system evolution, i.e. initial states that fill the energy shell ergodically, may lead to thermalization even for models in the integrable domain. On the other hand, initial states with energies too close to the edges of the spectrum may not thermalize even if the system is chaotic. We also discuss the role of the initial states and the presence of interactions in the relaxation process of several few-body observables. Our numerical studies are based on full exact diagonalization of Heisenberg spin-1/2 systems.
