Through Haldane's construction, the fractional quantum Hall states on a two-sphere were shown to be the ground states of one-dimensional SU(2) spin Hamiltonians. In this Letter we generalize this construction to obtain a new class of SU(N) spin Hamiltonians. These Hamiltonians describe center-of-mass-position conserving pair hopping fermions in space dimension d>/=2.
通过霍尔丹构造,二维球面上的分数量子霍尔态被证明是一维SU(2)自旋哈密顿量的基态。在本信函中,我们推广此构造以获得一类新的SU(N)自旋哈密顿量。这些哈密顿量描述了空间维度d≥2中质心位置守恒的对跳费米子。
