Disorder-mediated synchronization resonance in coupled semiconductor lasers
Li-Li Ye, Nathan Vigne, Fan-Yi Lin +2
Disorder can profoundly influence synchronization in networks of nonlinear oscillators, sometimes enhancing coherence through external tuning. In semiconductor lasers, however, ach…
Optimal sparse networks for synchronization of semiconductor lasers
Li-Li Ye, Nathan Vigne, Fan-Yi Lin +2
The inevitable random frequency differences among semiconductor lasers present an obstacle to achieving their collective coherence, but previous worked showed that fully (all-to-al…
Floquet quantum many-body scars in the tilted Fermi-Hubbard chain
Jun-Yin Huang, Li-Li Ye, Ying-Cheng Lai
The one-dimensional tilted, periodically driven Fermi-Hubbard chain is a paradigm in the study of quantum many-body physics, particularly for solid-state systems. We uncover the em…
Controlling nonergodicity in quantum many-body systems by reinforcement learning
Li-Li Ye, Ying-Cheng Lai
Finding optimal control strategies to suppress quantum thermalization for arbitrarily initial states, the so-called quantum nonergodicity control, is important for quantum informat…
Entanglement engineering of optomechanical systems by reinforcement learning
Li-Li Ye, Christian Arenz, Joseph M. Lukens +1
Entanglement is fundamental to quantum information science and technology, yet controlling and manipulating entanglement -- so-called entanglement engineering -- for arbitrary quan…
High-order exceptional points and stochastic resonance in pseudo-Hermitian systems
Shirin Panahi, Li-Li Ye, Ying-Cheng Lai
Exceptional points, a remarkable phenomenon in physical systems, have been exploited for sensing applications. It has been demonstrated recently that it can also utilize as sensory…
