Q-膜

Q-branes

Steven Abel, Alex Kehagias

摘要:

讨论了弦条件下的非拓扑孤子(Q球)。我们的主要结果是,Myers的介电D膜系统在其世界体积上存在非交换的Q球解,其中$N$ D $p$ -膜在Q球外松弛为标准介电形式,但在其中心呈现一个更弥散的构型.我们还考虑了Q球如何在大量的额外维理论,或包裹膜的行为。我们证明了它们携带Kaluza-Klein荷,并具有与正常粒子一样的Kaluza-Klein态塔,并通过在具有特定对数势的模型中找到精确的Q球解来讨论表面能效应.

英文摘要:

Non-topological solitons (Q-balls) are discussed in some stringy settings. Our main result is that the dielectric D-brane system of Myers admits non-abelian Q-ball solutions on their world-volume, in which $N$ D$p$-branes relax to the standard dielectric form outside the Q-ball, but assume a more diffuse configuration at its centre. We also consider how Q-balls behave in the bulk of extra-dimensional theories, or on wrapped branes. We demonstrate that they carry Kaluza-Klein charge and possess a corresponding Kaluza-Klein tower of states just as normal particles, and we discuss surface energy effects by finding exact Q-ball solutions in models with a specific logarithmic potential.
