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…

Jian Liu, Lei Chen, Ka-Di Zhu
We propose an optomechanical nano-gravimeter based on exceptional points. The system is a coupled cavity optomechanical system, in which the gain and loss are applied by driving th…
Ultrasensitive optomechanical detection of an axion-mediated force based on a sharp peak emerging in probe absorption spectrum
Lei Chen, Jian Liu, Kadi Zhu
Axion remains the most convincing solution to the strong-CP problem and a well-motivated dark matter candidate, causing the search for axions and axion-like particles(ALPs) to attr…

Lei Chen, Jian Liu, Ka Di Zhu
We present an atomic, molecular, and optical physics based method for the purpose of search for axial-vector mediated dipole-dipole interaction between electrons. In our scheme, ap…
A micro dalton resolution mass sensor using optically cooled microdisks via short-time measurement
Jian Liu, Ka Di Zhu
We propose a mass sensor using optically trapped and cooled dielectric microdisks with "measuring after cooling" scheme. The center-of-mass motion of a trapped particle in vacuum c…
Detecting large extra dimensions with optomechanical levitated sensors
Jian Liu, Ka-Di Zhu
Numbers of tabletop experiments have made efforts to detect large extra dimensions for the range from solar system to submillimeter system, but the direct evidence is still lacking…

Jian Liu, Ka-Di Zhu
Particles with electric charge 10^(-12)e in bulk mass are not excluded by present experiments. In the present letter we provide a feasible scheme to measure the millicharged partic…
