论文摘要
我们考虑了最近提出的介电Skyrme模型，而有或不增加标准Pion质量项。然后，我们写下了Bogomol'nyi-Type能量界限，以弥补和大规模案例。我们进一步表明，除了采取严格的BPS限制时，天空是由3个正交偶极子制成的，这些偶极始终可以放置在其吸引人的渠道并形成绑定状态。最后，我们从数值上研究了该模型，并发现，在达到现实的结合能量之前，天空成为分离良好的点粒样天空的结合状态。通过足够接近BPS限制，我们能够获得与实验相比的经典结合能。
We consider the dielectric Skyrme model proposed recently, with and without the addition of the standard pion mass term. Then we write down Bogomol'nyi-type energy bounds for both the massless and massive cases. We further show that, except for when taking the strict BPS limit, the Skyrmions are made of 3 orthogonal dipoles that can always be placed in their attractive channel and form bound states. Finally, we study the model numerically and discover that, long before realistic binding energies are reached, the Skyrmions become bound states of well-separated point-particle-like Skyrmions. By going sufficiently close to the BPS limit, we are able to obtain classical binding energies of realistic values compared with experiments.
