Principal Investigator

Yanan Dai

Yanan is an assistant professor in the department of physics, Southern University of Science and Technology (SUSTech). He obtained his B.S. degree in physics at Shandong university in 2013, and Ph.D. degree in physics at The University of Pittsburgh in 2019. Before joining SUSTech in Aug. 2022, he worked as a postdoctoral research scientist in the department of chemistry at the Columbia University. His research interests include Poincaré engineering of surface plasmons, topological plasmons, excited state dynamics, and the development of novel ultrafast spectromicroscopies. His Ph.D. thesis was awarded as the outstanding dissertation by the International Organization of Chinese Physicists and Astronomers (OCPA).

Ph.D Students

Minghong Sun

September 2023 – now

Based on pump-probe techniques, ultrafast spectroscopy methods such as transient reflection spectroscopy and time-resolved magneto-optical Kerr effect are used to characterize the dynamics of quasiparticles like carriers and phonons in alternating magnets and charge density wave materials.

Peng Tan

September 2022 – now

Peng is currently working on transient reflection spectroscopy.

Qian Chen

September 2024 – now

Qian Chen’s research interests revolve around the generation and ultrafast dynamics of optical vortices in surface plasmons, with a special focus on shaping the spatiotemporal properties of these vortices.

Haoqiang Hu

September 2023 – now

a) Herriott-type multi-pass cell for high power pulse compression; b) multiphoton excitation and plasmonic coupled modulation with photoemission electron microscopy

Jukun Zhan

December 2023 – now

Jukun Zhan specializes in steady-state spectroscopy, focusing on the measurement of photoluminescence (PL), second harmonic generation (SHG), and magneto-optical Kerr effect (MOKE) in nanomaterials.
