正弦密度分布的受激中微子转换

Stimulated Neutrino Transformation with Sinusoidal Density Profiles

James P. Kneller, Gail C. McLaughlin, Kelly M. Patton

摘要:

量子系统的状态之间的大振幅振荡可以由频率类似于状态的能级分裂或其一小部分的正弦外部电势激发。当施加的频率等于能级分裂的整数分数时的情况被称为参数共振。我们研究这种效应的中微子分析和数值的情况下,任意数量的中微子口味。我们寻找的环境中的效果可以观察到,并发现超新星是一个现实的可能性,由于大密度和大振幅波动的必要性。中微子通过模型超新星传播的数值和分析结果的比较表明,它是可以预测的位置和强度的受激跃迁发生。

英文摘要:

Large amplitude oscillations between the states of a quantum system can be stimulated by sinusoidal external potentials with frequencies that are similar to the energy level splitting of the states or a fraction thereof. Situations when the applied frequency is equal to an integer fraction of the energy level splittings are known as parametric resonances. We investigate this effect for neutrinos both analytically and numerically for the case of arbitrary numbers of neutrino flavors. We look for environments where the effect may be observed and find that supernova are the one realistic possibility due to the necessity of both large densities and large amplitude fluctuations. The comparison of numerical and analytic results of neutrino propagation through a model supernova reveals it is possible to predict the locations and strengths of the stimulated transitions that occur.
