Phase-locked phonon laser enhanced ultra-weak force measurement
Yu Zheng, Long Wang, Lyu-Hang Liu +5
Optically levitated micro- and nanoparticles are an ideal optomechanical platform for precision measurements, particularly enabling the detection of ultraweak forces. Nevertheless,…
From Alerts to Intelligence: A Novel LLM-Aided Framework for Host-based Intrusion Detection
Danyu Sun, Jinghuai Zhang, Jiacen Xu +3
Host-based intrusion detection system (HIDS) is a key defense component to protect the organizations from advanced threats like Advanced Persistent Threats (APT). By analyzing the…
Optimal Position Detection of an Optically Levitated Mie Particle
Long Wang, Lei-Ming Zhou, Yuan Tian +4
We theoretically investigate the problem of position detection of an optically levitated Mie particle. The information radiation field (IRF) is proposed and defined to characterize…
A nano vacuum gauge based on second-order coherence in optical levitation
Lyu-Hang Liu, Yu Zheng, Yuan Tian +3
Accurate measurement of pressure with a wide dynamic range holds significant importance for various applications. This issue can be realized with a mechanical nano-oscillator, wher…
