具有实能量的复BPS Skyrmions

Complex BPS Skyrmions with real energy

Francisco Correa, Andreas Fring, Takanobu Taira

摘要:

我们提出并研究了几个复杂的版本的扩展和限制的Skyrme模型与一个定义良好的Bogomolny-Prasad-Sommerfield(BPS)限制。所研究的模型具有复杂的扭结,反扭结,半扭结,无质量和纯虚牛顿BPS的解决方案,都有真正的能量。当一个修正的反线性CPT-对称性将哈密顿泛函映射到它的宇称时间反演复共轭上,并将解场映射到它本身或一个具有简并能量的新场上时,特定解的能量的真实性得到了保证。除了已知的BPS Skyrmion配置,我们发现新的类型,我们称之为步骤,尖点,壳,和纯粹的想象力的Skyrmion解决方案。

英文摘要:

We propose and investigate several complex versions of extensions and restrictions of the Skyrme model with a well-defined Bogomolny-Prasad-Sommerfield (BPS) limit. The models studied possess complex kink, anti-kink, semi-kink, massless and purely imaginary compacton BPS solutions that all have real energies. The reality of the energies for a particular solution is guaranteed when a modified antilinear CPT-symmetry maps the Hamiltonian functional to its parity time-reversed complex conjugate and the solution field to itself or a new field with degenerate energy. In addition to the known BPS Skyrmion configurations we find new types that we refer to as step, cusp, shell, and purely imaginary compacton solutions.
