摘要
已移除以待修改。对更大截断 M 的对角化表明，确定的尺寸效应依赖于 M。随 M 的标度表明，在热力学极限下，斯格明子波函数趋向于平移不变硬核波函数。有限的 M 破坏了平移不变性，同时指数地抑制了波函数的尾部。细节将另行发表。

备注
Removed to be revised. Diagonalization for a larger cut-off M shows that the definite size effects are M-dependent. Scaling with M shows that in the thermodynamic limit the skyrmion wave-function tends to the translationally invariant hard core wave function. Finite M breaks translational invariance and at the same time it exponentially suppresses the tail of the wave-function. Details will be published
