本文综述了近年来在计算具有拓扑结构的经典孤子能量的量子修正方面的进展，包括一维多孤子模型和三维弦结构。利用解析延拓技术有效地组织计算，我们展示了量子校正如何影响Shifman-Voloshin模型中孤子的稳定性，稳定带电的电弱弦耦合到一个重费米子偶极子，并绑定Nielsen-Olesen涡在经典的过渡I型和II型超导体。
We review recent progress in the computation of leading quantum corrections to the energies of classical solitons with topological structure, including multi-soliton models in one space dimension and string configurations in three space dimensions. Taking advantage of analytic continuation techniques to efficiently organize the calculations, we show how quantum corrections affect the stability of solitons in the Shifman-Voloshin model, stabilize charged electroweak strings coupled to a heavy fermion doublet, and bind Nielsen-Olesen vortices at the classical transition between type I and type II superconductors.
