我们讨论了在旋转坐标系中边界效应对费米子物质的重要性。通过在零温下的显式计算，我们证明了只要边界条件得到适当的实现，费米子和反费米子的标量凝聚体就不能被旋转所改变。在有限温度下和/或在足够强的磁场取代边界效应的情况下，这种情况发生了质的变化。因此，要将转动解释为有效的化学势，关键是要考虑进一步的环境影响，如有限的温度和磁场。
We discuss the importance of boundary effects on fermionic matter in a rotating frame. By explicit calculations at zero temperature we show that the scalar condensate of fermion and anti-fermion cannot be modified by the rotation once the boundary condition is properly implemented. The situation is qualitatively changed at finite temperature and/or in the presence of a sufficiently strong magnetic field that supersedes the boundary effects. Therefore, to establish an interpretation of the rotation as an effective chemical potential, it is crucial to consider further environmental effects such as the finite temperature and magnetic field.
