Experimental Sensing Quantum Atmosphere of a Single Spin
I did independent research into the new concept Quantum atmosphere (QA), designed the experimental sequence to measure the spectroscopic properties in the QA of a nuclear spin based on NV center. I simulated the spin evolution under the pulse sequence and performed the experiment to realize my proposal. I processed the data with Origin and MATLAB and included the results in my first-author paper, which is now under the review of Phys. Rev. Lett.
Magnetic gradient Fourier imaging
1. I computationally simulated the experimental scheme which is aimed at imaging Moire magnets with ensemble NV centers.
2. I developed the 2D sparse random sampling points processing method to analyze the spectrum and reconstruct the 2D periodic magnetic field distribution.
Homebuilt desktop device to search for dark matter
1. I took part in the construction of the optical path for collecting the photons emitted by NV centers.
2. I calculated the exotic spin-dependent dipole-dipole interaction mediated by axion-like particles and simulated the effective magnetic field of the NV center generated by the polarized spin ensembles in cylindrical pentacene.
