论文摘要
异国情调的物质可以与常规命令共存,使得量规场和分数激发可以在看似有序的状态下占上风。我们探索带有偶极式双极双线器的Spin-1/2 pyrochlores中的库仑反铁磁铁。这种分数化的抗铁磁态带有抗磁磁性和新出现的量子电动力学,并带有无间隙仪表光子和分数化的准粒子。我们解释了特征性的物理特性,包括热力学和这种外来状态的动力学。例如,这包括异常大的$ t^3 $比热和非弹性中子散射中的宽旋子连续体。我们讨论了实验和材料的相关性,并期望这项工作激发了在有序磁体中寻找异国物理学的兴趣。
Exotic state of matter could coexist with conventional orders such that the gauge fields and fractionalized excitations could prevail in a seemingly ordered state. We explore the Coulombic antiferromagnet in the spin-1/2 pyrochlores with dipole-octupole doublets. This fractionalized antiferromagnetic state carries both antiferromagnetic order and emergent quantum electrodynamics with the gapless gauge photon and fractionalized quasiparticles. We explain the characteristic physical properties including the thermodynamics and the dynamics of this exotic state. This includes for example the anomalously large $T^3$ specific heat and the broad spinon continuum in the inelastic neutron scattering. We discuss the experimental and material's relevance and expect this work to inspire interests in the search of exotic physics among the ordered magnets.
