四维石墨烯与手征费米子
Four-dimensional graphene and chiral fermions
摘要：
基于相对论狄拉克方程对石墨烯电子结构的描述，将其推广到四维，得到了描述两个物种并具有精确手征对称性的严格局域费米子作用。这是众所周知的“不去”定理所要求的最小物种数。
英文摘要：
Motivated by the description of the graphene electronic structure in terms of the relativistic Dirac equation, a generalization to four dimensions yields a strictly local fermion action describing two species and possessing an exact chiral symmetry. This is the minimum number of species required by the well known ``no-go'' theorems.
