报告摘要:Quantum spin liquids (QSLs) represent a novel state of matter in which no spontaneous symmetry is broken and the spins remain in the liquid-like state even at absolute zero temperature. They hold great potentials in quantum computation and communication. Furthermore, it is believed that the understanding of QSLs may help solve the long-term puzzle of high-temperature superconductivity. For these reasons, QSLs have been studied extensively in the past 45 years or so, but so far there still appear to be no ideal QSL materials. Neutron scattering plays an essential role in identifying QSLs, as it probes the spin correlations directly and provides crucial information in the energy and momentum space of the spins.
