论文摘要
在填充因子$ν= 0，\ pm1 $时，石墨烯的基态是一种特定的SU（4）Ferromagnet，它托有丰富的相图以及几种旋转，假蛋白或“纠缠”磁蛋白模式。在最近的实验中，我们研究了$ν= -1 | 0 | -1 $ fabry-pérotmagnonic交界处。如果$ν= 0 $的基态旋转极化，则存在两种旋转模式，它们会干扰并创建跳动模式，而伪旋转模式则反映了。如果$ν= 0 $地面状态为伪旋转，则假设元素也会发生相同的情况。对这种干扰模式的观察将提供有关低能量各向异性的信息，从而提供基础状态。
At filling factor $ν=0,\pm1$, the ground state of graphene is a particular SU(4) ferromagnet which hosts a rich phase diagram along with several spin, pseudospin or "entanglement" magnon modes. Motivated by recent experiments, we study a $ν=-1|0|-1$ Fabry-Pérot magnonic junction. If the ground state at $ν=0$ is spin polarized, there exist two spin modes which interfere and create a beating pattern, while pseudospin modes are reflected. The same scenario occurs for pseudospin magnon if the $ν=0$ ground state is pseudospin polarized. The observation of such an interference pattern would provide information on the low-energy anisotropies and thus on the ground state.
