Periodically driven ergodic and many-body localized quantum systems

Ponte, Pedro, Chandran, Anushya, Papić, Z. et al.

Understand

We study dynamics of isolated quantum many-body systems under periodic driving.

  • We consider a driving protocol in which the Hamiltonian is switched between two different operators periodically in time.
  • The eigenvalue problem of the associated Floquet operator maps onto an effective hopping problem in energy space.
  • Using the effective model, we establish conditions on the spectral properties of the two Hamiltonians for the system to localize in energy space.
