Congratulations to Dr.Ji, for Successfully defending his thesis! 

Lingjing's experimental efforts substantially refined our optical spin-wave control technique, particularly in the nonlinear excitation regime.

Special thanks to the committee professors: Zhang Hao, Rui Jun, Feng Lei, Pengfei and Xiaopeng.

Equipped with advanced quantum optical knowledge, Lingjing is now heading toward precision measurements in industry! We wish him all the best!
