论文摘要
我们表明，光谱壁，即，在将原始的骨模型耦合到费米子之后，由于正常模式向连续光谱的过渡而存在，这是由于正常模式向连续光谱的过渡而产生的。如果玻色子或费米恩场处于激发状态，则可以体验该光谱壁。此外，在穿过光谱壁的同时，可以将传入的扭结绑定状态分为纯粹的骨扭结，该状态继续移动到空间无穷大，而在壁前散布的费米云。
We show that a spectral wall, i.e., an obstacle in the dynamics of a bosonic soliton, which arises due to the transition of a normal mode into the continuum spectrum, exists after coupling the original bosonic model to fermions. This spectral wall can be experienced if the boson or fermion field is in an excited state. Furthermore, while passing through a spectral wall, an incoming kink-fermion bound state can be separated into purely bosonic kink, which continues to move to spatial infinity and a fermionic cloud that spreads in the region before the wall.
