论文摘要
我们研究了最近发现的扭结孤子的量子效应，这些词素是通过耦合到单个激发的费米式结合状态来自一构建的。我们的研究基于这样的观察，即在半古典膨胀中，应平等处理该单一级别和狄拉克海的能量。对于这些扭结解决方案，我们将狄拉克海的能量作为费米昂真空极化能。我们发现它是实质性的，并且通常超过了结合单个水平的能量增益。
We study quantum effects of recently discovered kink solitons which are constructed self-consistently by coupling to a single, excited fermion bound state. Our studies are based on the observation that in a semi-classical expansion the energies of this single level and of the Dirac sea should be treated equally. For these kink solutions we compute the energy of the Dirac sea as the fermion vacuum polarization energy. We find it to be substantial and to typically outweigh the energy gain from binding the single level.
