Fundamental limit of linear bosonic sensors and the Schawlow-Townes laser linewidth limit
Qi Geng, Ka-Di Zhu
In recent years, many peculiar sensors have been proposed, such as the sensors based on exceptional points, Parity-Time symmetric structures or non-reciprocal systems. It is crucia…
Proposal for constraining non-Newtonian gravity at nm range via criticality enhanced measurement of resonance frequency shift
Lei Chen, Jian Liu, Ka-di Zhu
We propose a quantum mechanical method of constraining non-Newtonian gravity at the nanometer range. In this method, a hybrid electro-optomechanical system is employed. Applying a…
Proposal for measuring Newtonian constant of gravitation at an exceptional point in an optomechanical system
Lei Chen, Jian Liu, Ka-di Zhu
We develop a quantum mechanical method of measuring the Newtonian constant of gravitation, G. In this method, an optomechanical system consisting of two cavities and two membrane r…
Constraining Axion-to-Nucleon interaction via ultranarrow linewidth in the Casimir-less regime
Lei Chen, Jian Liu, Kadi Zhu
In this paper we develop a quantum optical method to detect the axion-nucleon interaction. We ultilize a levitated optomechanical system consisting of a silica nanosphere and an op…
Measurement of Neutron Lifetime and Purcell Effect
Fei He, Ka-Di Zhu
Purcell effect predicts that spontaneous radiation is not an intrinsic property of matter, but is affected by the environment in which it is located, and is the result of the inter…
Machine Learning Percolation Model
Shu Cheng, Fei He, Huai Zhang +2
Recent advances in machine learning have become increasingly popular in the applications of phase transitions and critical phenomena. By machine learning approaches, we try to iden…
