论文摘要
我们建议，磁极的唯一可能实现是出现的，它是弯曲时空中扭转缺陷的伪影。该特殊阶段的特征是真空中一级重力重力的退化度量时空溶液。 （明显的）磁电荷显示为拓扑来源，由Nieh-Yan指数的较低维度给出。在距离的可逆度量阶段，即使缺陷本身仍然隐藏，这种拓扑电荷也会反映为（磁性）reissner-nordstrom电荷到渐近观察者。
We propose that the only possible realization of a magnetic pole is emergent, it being an artefact of a torsion defect in a curved spacetime. This special phase is characterized by a class of degenerate metric spacetime solutions of first order gravity in vacuum. The (apparent) magnetic charge is shown to have a topological origin, given by a lower dimensional counterpart of the Nieh-Yan index. At the invertible metric phase at a distance, this topological charge gets reflected as the (magnetic) Reissner-Nordstrom charge to an asymptotic observer, even though the defect itself remains hidden.
