Rigorous Bound on Energy Absorption and Generic Relaxation in Periodically Driven Quantum Systems
Takashi Mori, Tomotaka Kuwahara, Keiji Saito
We discuss the universal nature of relaxation in isolated many-body quantum systems subjected to global and strong periodic driving. Our rigorous Floquet analysis shows that the en…
Exponential bound on information spreading induced by quantum many-body dynamics with long-range interactions
Tomotaka Kuwahara
The dynamics of quantum systems strongly depends on the local structure of the Hamiltonian. For short-range interacting systems, the well-known Lieb-Robinson bound defines the effe…
Floquet-Magnus Theory and Generic Transient Dynamics in Periodically Driven Many-Body Quantum Systems
Tomotaka Kuwahara, Takashi Mori, Keiji Saito
This work explores a fundamental dynamical structure for a wide range of many-body quantum systems under periodic driving. Generically, in the thermodynamic limit, such systems are…
Local reversibility and entanglement structure of many-body ground states
Tomotaka Kuwahara, Itai Arad, Luigi Amico +1
The low-temperature physics of quantum many-body systems is largely governed by the structure of their ground states. Minimizing the energy of local interactions, ground states oft…
