Dynamics in strongly disordered system
Under strong disorder, the coherent dynamics of a quantum system may be qualitatively different from that of a clean system. Recent developments of many-body localization suggest that the dynamics of such systems may be rather simpler than solving a full quantum problem and sometimes even controllable thanks to its localized nature. We study the nature of dynamics in such systems in both theory and experiments.
- Quantum control of many-body localized states
- Critical thermalization of a disordered dipolar spin system in diamond
- Observation of discrete time-crystalline order in a disordered dipolar many-body system
- Critical time crystals in dipolar systems
Control and tomography of many-body Hamiltonian
One of the most outstanding challenges in the experimental study of quantum many-body dynamics is the difficulty of realizing systems with a desired Hamiltonian. Also, even if such a system is built, the “in vivo” characterization of its Hamiltonian remains non-trivial. We study the theoretical tool sets to circumvent theses difficulties.
