ABSTRACT
Strongly correlated Mott insulators could harbor various magnetic excitations that are charge neutral and hidden from usual electrical transport measurement, while thermal transport is powerful to detect the elementary excitations therein. Besides the more conventional and well-understood magnon excitations in the ordered state, here we discuss thermal Hall effects of the appealing fractionalized excitations in the quantum disordered spin liquid phase, which reveal the intriguing couplings between emergent gauge fields and fractionalized spinon or “magnetic monopole”, and provide strong evidence to confirm spin liquids.
BIOGRAPHY
Prof Gang Chen received his bachelor's degree from USTC in 2004 and graduated with the University's highest honor. He received his PhD in 2010 from Univ of California, Santa Barbara, working with Prof Leon Balents from the Kavli Institute for Theoretical Physics. He was appointed the professor position in 2015 at Fudan University, and elected into the 1000- youth-talent program. He was awarded the Daniel Tsui Fellowship from The University of Hong Kong in 2017, and Qiushi outstanding Youth scientist in 2018. He is currently working at University of Hong Kong. Prof Chen has a broad interest in condensed matter theory, and most of his works are experimentally motivated.
