Magnetic ground state of the candidate quantum ice material Pr2Sn2O7

Quantum spin ice is a novel form of matter in which the spins remain dynamic even at absolute zero due to quantum fluctuations. The requirements on the single-ion wavefunction...量子自旋冰（Quantum spin ice）是一种新颖的物质形态，其自旋即便在绝对零度下也会因量子涨落而始终保持动态演化状态。针对单离子波函数（single-ion wavefunction）的相关要求……
