密QCD中非阿贝尔涡旋中Majorana费米子与Nambu-Goldstone玻色子的耦合

Coupling between Majorana fermions and Nambu-Goldstone bosons inside a non-Abelian vortex in dense QCD

Chandrasekhar Chatterjee, Mattia Cipriani, Muneto Nitta

摘要:

夸克物质在高密度下可能表现出色超导性。作为金属超导体中的磁通量管,色磁通量管作为非阿贝尔涡旋出现在高密度QCD色香味锁相中。属于三重态表象的${\mathbb C}P^2$南武-戈德斯通玻色子和马约拉纳费米子被认为局限于非阿贝尔涡旋周围。本文用非线性实现方法确定了这些玻色子模和费米子模的耦合。

英文摘要:

Quark matter at high density may exhibit color superconductivity. As magnetic flux tubes in metallic superconductors, color magnetic flux tubes as non-Abelian vortices appear in the color-flavor locked phase of high density QCD. ${\mathbb C}P^2$ Nambu-Goldstone bosons and Majorana fermions belonging to the triplet representation are known to be localized around a non-Abelian vortex. In this paper, we determine the coupling of these bosonic and fermionic modes by using the nonlinear realization method.
