Guangxin Ni

Guangxin Ni is an Assistant Professor in the Department of Physics at Florida State University, where he joined the faculty in 2020. His research program focuses on experimental condensed matter physics and nano-optics, utilizing advanced techniques to probe quantum phenomena in two-dimensional materials and van der Waals heterostructures with unprecedented spatial, spectral, and temporal resolution.

Dr. Ni received his Ph.D. in Physics from the National University of Singapore in 2013, followed by postdoctoral research at the University of California San Diego (2014-2017) and Columbia University (2017-2019). His technical expertise spans nano-optical imaging, ultrafast spectroscopy, and nano-electronic measurements.

His primary research interests involve experimental condensed matter physics and optical physics, specifically using nano-optics coupled with nano-electronics to investigate emergent phenomena in quantum materials. Key areas include two-dimensional materials, van der Waals heterostructures, multifunctional quantum systems, and electromagnetic metamaterials. His group employs visible, infrared, and terahertz nano-imaging alongside ultrafast pump-probe spectroscopy to achieve nanoscale characterization of electronic, magnetic, and lattice dynamics.

Analysis of Dr. Ni's recent publications reveals a concentrated focus on twist-engineered quantum materials, polaritons, and electronic correlations. His work frequently explores moiré superlattices in 2D systems, plasmonics in novel quantum materials, and multiferroic phenomena, bridging fundamental condensed matter physics with applications in nanophotonics and quantum information science.

Dr. Ni has received exceptional recognition through prestigious early-career awards:

• Department of Energy Early Career Award (2021)
• NSF CAREER Award (2022)
• PRF Early Investigator Award (2023)

He leads the active Ni Lab at FSU, supported by these major grants including the NSF CAREER project "Towards Novel Twist Polaritonics in 2D Crystals and Devices." While specific student names aren't provided, he mentors graduate students in the Physics department. His research group maintains state-of-the-art capabilities for nano-optical experiments and collaborates extensively within the quantum materials community.
