Entanglement of light and multiple vibrations is a key resource for multichannel quantum
information processing and memory. However, entanglement generation is generally …

The simultaneous ground-state cooling of multiple degenerate or near-degenerate
mechanical modes coupled to a common cavity-field mode has become an outstanding …

We study tunable optomechanically induced transparency by controlling the dark-mode
effect induced by two mechanical modes coupled to a common cavity field. This is realized …

The development of quantum optomechanics enables the manipulation of the quantum state

We propose how to achieve significantly enhanced quantum refrigeration and entanglement
by coupling a pumped auxiliary cavity to an optomechanical cavity. We obtain both …

We theoretically study the dynamics of an optomechanical system, consisting of a passive
optical mode and an active mechanical mode, in the PT-and broken-PT-symmetric regimes …

The dark-mode effect is a stubborn obstacle for ground-state cooling of multiple degenerate
mechanical modes optomechanically coupled to a common cavity-field mode. Here we …

We propose a domino-cooling method to realize simultaneous ground-state cooling of a
coupled mechanical-resonator chain through an optomechanical cavity working in the …

Narrow linewidth is a long-pursued goal in precision measurement and sensing. We
propose a parity-time symmetric (PT-symmetric) feedback method to narrow the linewidths of …

Quantum entanglement not only plays an important role in the study of the fundamentals of
quantum theory, but also is considered as a crucial resource in quantum information …
