Qi Zhang joined Nanjing University as a professor in Nov. 2019. His research is focusing on exploring light-matter interactions and milli-eV low-energy excitations in quantum materials. Various optical methods (e.g. THz / Raman spectroscopy, magneto-optics) are utilized to unveil the novel quantum phenomena, and further manipulate the quantum states / phases in low dimensional quantum materials at ultrafast time scales.

 

Education and experience:

2018-2019  Research associate, University of Washington.

2016-2018  Alexey Abrikosov Fellow, Argonne National Laboratory

2015 Ph.D,  Rice University.

2010 M.S.,  Peking University.

2007 B.S.,   Nanjing University.


担任课程

《超快光学与技术》

研究领域

我们用光探索和调控量子材料。我们运用从太赫兹(THz)到紫外波段的各种超快及非线性光谱揭示量子材料中的新奇物理现象,尤其关注毫电子伏量级(meV)的低能激发、非线性效应、及其超快非平衡动力学。 我们研究兴趣包括量子磁性,低维自旋与关联电子体系,以及反铁磁自旋波物理。


我们计划每年招收2名博士生或硕博连读研究生,并热诚邀请博士后及专职科研人员的加盟,同时我们也欢迎对光谱研究感兴趣的本科生进组开展研究,有意者请邮件联系。
