旋转介质中的中微子能量量子化

Neutrino energy quantization in rotating medium

Alexander Grigoriev, Alexander Studenikin

摘要:

在中微子质量为零的极限条件下,在极坐标系中求出了旋转介质中修正的狄拉克方程的精确解。活性左手粒子的解表现出与在恒定磁场中运动的带电粒子所特有的性质相似的性质。因此,旋转物质中的粒子具有圆形轨道,其能级类似于磁场中的朗道能级。这个问题的物理实现是中微子在旋转的中子星中的运动。这种形成束缚态的运动特征导致了对中微子俘获新机制的预言。所得到的解可用于详细描述中子星中相对论性和近无质量的中微子动力学。所得结果进一步发展了“精确解方法”在稠密物质存在下粒子相互作用的应用。

英文摘要:

Exact solution of the modified Dirac equation in rotating medium is found in polar coordinates in the limit of vanishing neutrino mass. The solution for the active left-handed particle exhibit properties similar to those peculiar for the charged particle moving in the presence of a constant magnetic field. Accordingly, the particle in the rotating matter has circle orbits with energy levels, analogous to the Landau levels in magnetic field. The relevant physical realization of the problem is motion of neutrino inside the rotating neutron star. The feature of such motion to form binding states leads to the prediction of the new mechanism for neutrino trapping. The solution found can be used for detailed description of relativistic and nearly massless neutrino dynamics in neutron stars. Results obtained further develop the "method of exact solutions" in application to particle interactions in presence of dense matter.
