我们描述基态的相关电子系统中，电子分成单独的准粒子携带其自旋和电荷，并进入真实的马约拉纳费米子携带其费米统计。这样的母态提供了一个以前研究过的分数态的统一理论：它们的后代包括中性自旋S=1/2费米子自旋的绝缘和导电态，以及无自旋费米子电荷载流子的状态。我们说明这些想法的蜂窝晶格，与场理论的这种状态和它们的相变。
We describe ground states of correlated electron systems in which the electron fractionalizes into separate quasiparticles which carry its spin and its charge, and into real Majorana fermions which carry its Fermi statistics. Such parent states provide a unified theory of previously studied fractionalized states: their descendants include insulating and conducting states with neutral spin S=1/2 fermionic spinons, and states with spinless fermionic charge carriers. We illustrate these ideas on the honeycomb lattice, with field theories of such states and their phase transitions.
