Recently, a theoretical work titled “Cavity Quantum Electrodynamics Effects with Nitrogen Vacancy Center Spins Coupled to Room Temperature Microwave Resonators” has been reported by the Diamond Optoelectronic Materials and Devices team of the Institute of Materials Physics, School of Physics, Zhengzhou University in the internationally renowned physics journalPhysical Review Letters, in which light-induced spin cooling is proposed to counteract the spin-lattice relaxation of the N-vacancy color center spins. The possibility of realizing room temperature cavity quantum electrodynamic effect is predicted, and some predictions have been confirmed by experiments. Associate Professor Yuan Zhang, a young faculty member of the school, is the first author and corresponding author. Qilong Wu, a postgraduate student, is the co-first author. Professor Chongxin Shan and Professor Klaus Mølmer of Aarhus University are the co-corresponding authors. Zhengzhou University is the first unit.

The work is supported by National Natural Science Foundation of China, Henan Outstanding Overseas Scientist Program Center, and Danish National Research Foundation, among other projects.
