论文摘要
长期寻找具有低能量准颗粒的绝缘材料，这些材料载有电子量子数，但受充电以外的量子数 - 灵感来自中性自旋1/2激发，即安德森（Anderson）的共鸣 - 价值状态表现出所谓的蜘蛛，似乎在发现了一些磁场和磁性的量子范围后，似乎已经达到了一个磁场和磁性磁场后，似乎已经达到了一个相同的量子，包括相同的量子和磁性磁场。在这里，我们表明，这种异常行为与Luttinger表面的Landau的Fermi液体理论不一致。这就是单粒子绿色功能在零频率的布里渊区内的零的流形，从而定义了安德森构想的Spinon Fermi表面。
The long search for insulating materials that possess low-energy quasiparticles carrying electron's quantum numbers except charge - inspired by the neutral spin-1/2 excitations, the so-called spinons, exhibited by Anderson's resonating-valence-bond state - seems to have reached a turning point after the discovery of several Mott insulators displaying same thermal and magnetic properties as metals, including quantum oscillations in a magnetic field. Here, we show that such anomalous behaviour is not inconsistent with Landau's Fermi liquid theory of quasiparticles at a Luttinger surface. That is the manifold of zeros within the Brillouin zone of the single-particle Green's function at zero frequency, and which thus defines the spinon Fermi surface conjectured by Anderson.
