Abstract

Since the first successful isolation of graphene in 2004, the ever-expanding family of two-dimensional (2D) materials has demonstrated exceptional electrical, optical, thermal, and mechanical properties. They are widely regarded as holding significant application potential in areas such as next-generation electronic devices, sensing and detection, and chemical catalysis. On the other hand, 2D materials have also revealed a host of novel physical phenomena, including nontrivial-topology, strong correlations, and superconductivity. Recent research has shown that novel tuning knobs, such as twisting angles between layers, enable the emergence of various strongly correlated and topological quantum states of matter. As a result, 2D materials have become an exceptional platform for fundamental condensed matter physics research. This talk will cover a series of recent scientific discoveries in moiré superlattice systems based on 2D materials and discuss the new opportunities they present.

Bio

Tingxin Li is a condensed matter experimental physicist. He obtained his Ph.D. from Peking University in 2016, followed by postdoctoral research at Rice University and Cornell University. He joined Shanghai Jiao Tong University as a Tenure-Track Associate Professor in June 2021. His research focuses on exploring and studying emergent quantum phenomena in low-dimensional quantum materials. By integrating advanced nanofabrication techniques with low-temperature transport measurements, his research group has revealed a series of novel quantum phases, such as the fractional quantum anomalous Hall effect, in two-dimensional van der Waals materials and their moiré structures. He has published more than 40 papers with a total citation number over 4500 (google scholar). He received Xplorer Prize (2025), Asian Young Scientist Fellow (2025), Ruiyuan Young Scientist Award (2024).
