Overview of Academic Research
Dr. Cheng Cun-Feng is currently a professor at Hefei National Research Center for Microscale Material Science, the University of Science and Technology of China. In 2021, he has been selected as the youth project of the Chinese National Talents Program. Prof. Cheng has carried out a series of researches in the field of molecular precision spectroscopy. He developed cavity-enhanced laser spectroscopy technique, which has extremely high sensitivity and precision, and applied the technique for Kelvin metrology. He built the world's first cold molecular fountain and applied to precision measurements on molecules. He did the precision measurements on the two-electron system (H2) and obtained dissociation energy and vibrational energy of molecular hydrogen with unprecedented accuracy, and used the precision results to test the high accurate molecular theory including quantum electrodynamics.
