球对称时空中的旋量场

Spinor fields in spherically symmetric space-time

Bijan Saha

摘要:

在球对称时空的范围内,我们研究了非线性旋量场在形成具有球对称性的不同组态中的作用。旋量场能量动量张量的非对角分量的存在导致了对旋量场本身的严格限制。由于旋量场是引力场的源,度规函数也随之变化,只有在对度规函数附加某些条件的情况下,系统整体才有解。

英文摘要:

Within the scope of a spherically symmetric space-time we study the role of a nonlinear spinor field in the formation of different configurations with spherical symmetries. The presence of the non-diagonal components of energy-momentum tensor of the spinor field leads to some severe restrictions on the spinor field itself. Since spinor field is the source of the gravitational one, the metric functions also changes in accordance with it. The system as a whole possesses solutions only in case of some additional conditions on metric functions.
