Bio: Junjie He is an Assistant Professor at the Faculty of Science, Charles University, Prague, Czech Republic. He obtained his Ph.D. with Prof. Petr Nachtigall at Charles University in 2017, followed by research positions in Beijing and Chongqing, China (2017–2018). From 2019 to 2022, he was a postdoc and later the PI of a DFG-funded project in the group of Prof. Thomas Frauenheim at Universität Bremen, Germany. He has published over 80 papers with more than 3,600 citations and an h-index of 35 (as of August 2025).
Research: We use theoretical and computational methods to investigate exotic electronic structures, unconventional magnetism, and energy materials, with a focus on quantum materials and their ultrafast dynamics—especially under intense laser excitation. Our approach combines first-principles methods, including real-time time-dependent density functional theory and mixed quantum-classical dynamics (surface hopping and Ehrenfest dynamics), along with tight-binding model, atomistic spin model, and other simplified physical models.
Current research interests include:
Computational quantum materials
Electronic and magnetic properties of solids
Ultrafast magnetism and spin dynamics
Non-adiabatic carrier dynamics in catalytic and energy materials
Ultrafast control of ferroic and multiferroic materials
Spin-chiral phonon coupling and dynamics
