不成对复合费米子、拓扑激子和零模

Unpaired composite fermion, topological exciton, and zero mode

摘要:

复合费米子的成对态可以支持两种激发:涡旋和非成对复合费米子。我们构建了一个明确的微观描述的未成对的复合费米子,我们证明是准确的3-体模型相互作用,并可能,与库仑解决方案。这种理解揭示了一个未成对的复合费米子携带着一个电荷中性的“拓扑”激子,这反过来有助于微观上深入了解零模的起源,融合规则和能量学。

英文摘要:

The paired state of composite fermions is expected to support two kinds of excitations: vortices and unpaired composite fermions. We construct an explicit microscopic description of the unpaired composite fermions, which we demonstrate to be accurate for a 3-body model interaction, and, possibly, adiabatically connected to the Coulomb solution. This understanding reveals that an unpaired composite fermion carries with it a charge-neutral "topological" exciton, which, in turn, helps provide microscopic insight into the origin of zero modes, fusion rules, and energetics.
