IMX Talks - Ultrafast control of quantum materials on chip

Optical drive has emerged as a powerful tool for manipulating the functional properties of quantum materials on ultrashort timescales and provides the platforms to develop ultrafast electronics on chip. Despite extensive characterizations of these transient dynamics using optical, scattering, scanning, and photoemission techniques, their transport responses, which directly impact electronic circuit performance—remain largely unexplored. In this talk, I will show two examples based on recently developed ultrafast transport techniques, to probe the electrical responses from light-induced superconducting-like state in K₃C₆₀. Furthermore, I will demonstrate our recent efforts  and progress on developing full-electrical platform to achieve ultrafast electrical control of quantum materials.

Bio: Eryin Wang is currently a staff scientist at Max Planck Institute for the structure and dynamics of matter at Hamburg. His research focuses on ultrafast control of quantum material with strong optical and electrical pulses.
He received his doctorate from Tsinghua University in 2017, where he used angle-resolved photoemission spectroscopy to study the interfacial effect in two-dimensional material heterostructures. He received the Chorafas Prize for his Ph. D. work.
Since 2017 he started his postdoc research in Andrea Cavalleri’s laboratory at Max Planck Institute for the structure and dynamics of matter at Hamburg, and later in 2019 he received Humboldt fellowship to further support his research. In 2021, he became a staff scientist in Hamburg. His work focused on studying electrical dynamics in optically and electrically driven quantum materials with femtosecond optoelectronic platforms.
