有理数映射中的Skyrmion振动模

Skyrmion Vibration Modes within the Rational Map Ansatz

W. T. Lin, B. Piette

摘要:

我们研究了Skyrme模型在有理映射下的振动模式。我们表明,振动的径向配置文件和合理的映射是解耦的,我们认为明确的情况下B=1,B=2和B=4。然后,我们将我们的结果与Barnes等人数值计算得到的振动模式进行比较,并表明定性的有理映射再现了数值计算得到的振动模式,但这些模式的振动频率并不匹配得很好。

英文摘要:

We study the vibration modes of the Skyrme model within the rational map ansatz. We show that the vibrations of the radial profiles and the rational maps are decoupled and we consider explicitly the case B=1, B=2 and B=4. We then compare our results with the vibration modes obtained numerically by Barnes et al. and show that qualitatively the rational map reproduces the vibration modes obtained numerically but that the vibration frequencies of these modes do not match very well.
