石墨烯中的质量和马约拉纳费米子

Masses and Majorana fermions in graphene

Claudio Chamon, Chang-Yu Hou, Christopher Mudry, Shinsei Ryu, Luiz Santos

摘要:

我们回顾了石墨烯中所有36种可能的间隙开放不稳定性的分类,即,36相对论质量的二维狄拉克哈密顿量时,自旋,谷,和超导通道。然后,我们表明,在石墨烯中,它是可能实现奇数的马约拉纳费米子附加到超导序参量的涡旋,如果一个适当的层次结构的质量尺度到位。

英文摘要:

We review the classification of all the 36 possible gap-opening instabilities in graphene, i.e., the 36 relativistic masses of the two-dimensional Dirac Hamiltonian when the spin, valley, and superconducting channels are included. We then show that in graphene it is possible to realize an odd number of Majorana fermions attached to vortices in superconducting order parameters if a proper hierarchy of mass scales is in place.
