Mechanical degrees of freedom, which have often been overlooked in various quantum systems, studied for applications ranging from information processing to sensing. Here, we develop a hybrid platform consisting magnomechanical cavity and an optomechanical cavity, are coherently coupled by the straightway physical contact. The phonons system can be manipulated either with magnetostrictive interaction or optically through radiation pressure. Together mechanical state preparation sensitive...
An optical frequency comb is a spectrum of radiation which consists evenly spaced and phase-coherent narrow spectral lines initially invented in laser for metrology purposes. A direct analog combs the magnonic systems has not been demonstrated to date. In our experiment, we generate new resonator with giant mechanical oscillations through magnomechanical interaction. We observe contains up 20 lines, are separated by 10.08 MHz. The thermal effect based on strong pump power induces cyclic...
Phonon-based frequency combs that can be generated in the optical and microwave domains have attracted much attention due to small repetition rates simple setup. Here, we experimentally demonstrate a new type of phonon-based comb silicon optomechanical crystal cavity including both breathing mechanical mode (∼GHz) flexural modes (tens MHz). We observe strong competition between two approximate modes, i.e., 77.19 90.17 MHz, resulting only one preponderant lasing, while maintaining lasing...

Similarly, the reliable generation of nonclassical phonon is vital advancing engineerable solid-state devices and hybrid networks based on phonons. Here, we present a novel approach to generate quantum-correlated in suspended silicon microstructure initialized its motional ground state. By simultaneously implementing red- blue-detuned laser pulses, equivalent high-order...

Devonian cutinitic liptobiolith is a special type of coal formed during the early evolutionary stage land plants. The Baishaping and Damaidi coals are notable for their distinct papery, sheet-like texture, unusually high cutinite content (>50%), belonging to typical liptobiolith. They bituminous have suppressed vitrinite reflectance. Compared with III kerogen, these liptobioliths characterized by extremely yields volatile matter hydrogen contents owing enhanced contents. As indicated...
The ringing phenomenon has been studied in optical whispering gallery mode (WGM) resonators and can be used to sense the ultrafast process spectroscopy. Here we observe a magnomechanical system for first time, which is induced by interference between microwave photons converted from damped phonons probing photons. This eventually appears as transparency window even along with measured reflection spectrum, influenced scanning speed input power. Then, spectroscopy measure coupling strength...
