标题： (Un)balanced holographic superconductors with electric and spin motive force coupling

摘要： 我们研究(2+1)维中的全息相变，这些相变具有相互作用相，这是由于两个U(1)规范场之间的直接耦合产生的。 这可以解释为对偶模型中电和自旋电动势之间的非最小相互作用。 我们首先提出一个爱因斯坦-麦克斯韦方程的新解析解，该解描述了一个电荷不等于两个U(1)规范场渐近电荷之和的黑洞，并简要讨论在此解上无电荷标量毛发的形成。 然后我们研究在无电荷黑洞背景上带电标量毛发的形成，并讨论平衡和不平衡超导体的对偶描述。 显示英文摘要

摘要： We study holographic phase transitions in (2+1) dimensions that possess interacting phases which result from a direct coupling between the two U(1) gauge fields. This can be interpreted as a non-minimal interaction between the electric and spin motive forces of the dual model. We first present a new analytical solution of the Einstein-Maxwell equations that describes a black hole with charge non-equivalent to the sum of the asymptotic charges of the two U(1) gauge fields and briefly discuss formation of uncharged scalar hair on this solution. We then study the formation of charged scalar hair on an uncharged black hole background and discuss the dual description of balanced as well as unbalanced superconductors.
