Abstract

Searching for new particles beyond the standard model is crucial for understanding several fundamental conundrums in physics and astrophysics. Several hypothetical particles can mediate exotic
spin-dependent interactions between ordinary fermions, which enable laboratory searches via the detection of the interactions. We present a novel platform for investigating exotic spin-dependent interactions

with micrometer scales. NV centers in diamond have been utilized as quantum sensors to search for the exotic spin-dependent interactions. We first show an experiment to constrain the electron-nucleon

coupling with the force range 0.1-23 micrometers. We also show that upper limits on the exotic dipole-dipole interactions between electrons can be established at force range from 10-900 micrometers

by ours method.

Biography

Professor Xing Rong, born in1983, entered the University of Science and Technology of China in 2001. He got his PhD under the supervision of Prof. Jiangfeng Du. He focuses on development of instruments for magnetic resonance, which has been utilized to research solid-state quantum computing. He proposed and demonstrated experiments searching for ALPs on single-spin quantum sensors. He realized the Symmetric-time symmetrical Hamiltonian on the single quantum spin, which provides a route for further exploiting and understanding the exotic properties of parity-time symmetric Hamiltonian in quantum systems.
