v3.2.3
Currently under active study in condensed matter physics both theoretically and experimentally are quantum spin liquid (QSL) states, in which no long-range magnetic ordering appears at low temperatures due to strong quantum fluctuations of the magnetic moments. A comprehensive introduction and review to this field will be given. However, the existing QSL candidate materials all have their intrinsic disadvantages which lead to some contradictory experimental observations. Even though many studies have been conducted to understand this exotic quantum state, solid evidence for quantum fluctuations is scarce. Here we propose a newly discovered material with strong evidence for quantum fluctuations. Our experimental characterizations reveal that this new material appears to be the experimental realization of a quantum spin liquid ground state.
Ruidan Zhong obtained her Bachelor degree from Southeast University in 2011, and PhD degree from the State University of New York at Stony Brook in 2017. During her PhD, she conducted her research at Brookhaven National Laboratory, Condensed Matter Physics and Materials Science Department, where her research focuses on the experimental investigation on quantum materials including high-temperature superconductors and topological materials. After graduation, she moved to Princeton University and worked as a Postdoc in Prof. Bob Cava’s solid-state chemistry lab. Her research interest then is about novel quantum materials exploration and the magnetism in frustrated magnets.
