三角形光晶格中费米气体原子的极化平台

Polarization Plateau in Atomic Fermi Gas Loaded on Triangular Optical Lattice

M. Okumura, S. Yamada, M. Machida, T. Sakai

摘要:

为了证明原子费米气体是研究自旋相互作用受抑系统中尚未解决的问题的一个很好的实验现实,我们数值研究了在三角形光晶格上加载双组分原子费米气体所产生的Mott核态.因此,我们发现,高原状结构是观察到的莫特核心极化作为人口不平衡的函数。这些平台状态是由周围的金属区域吸收过量的不平衡以将平台状态保持在莫特核心内的柔性引起的。我们还发现自旋模式特有的莫特核心内的平台状态。

英文摘要:

In order to demonstrate that atomic Fermi gas is a good experimental reality in studying unsolved problems in frustrated interacting-spin systems, we numerically examine the Mott core state emerged by loading two-component atomic Fermi gases on triangular optical lattices. Consequently, we find that plateau like structures are observable in the Mott core polarization as a function of the population imbalance. These plateau states are caused by a flexibility that the surrounding metallic region absorbs the excess imbalance to keep the plateau states inside the Mott core. We also find spin patterns peculiar to the plateau states inside the Mott core.
