【摘要】 <正> Parker在Friedmann宇宙内粒子的产生一文中讨论过K=0的Friedmann时空中自由粒子的Dirac方程,Ford在Einstein宇宙的量子真空能量一文中讨论过Einstein时空自由粒子的Dirac方程。Frolov等在研究Friedmann时空中标量粒子和旋量粒子的产生过程的差别时,讨论过K=1的Friedmann时空中自由粒子的Dirac方程,他们用的是(?)矩阵方法。本文用旋量零标架方法研究了K=1的Friedmann时空自由粒子的Dirac更多还原

【Abstract】 The Dirac equation of free particles in Friedmann spacetime is studied in spinor null tetrad formalism in this paper. First we construct the null tetrad, from which the spin coefficients are derived. Next, the Dirac equation is decoupled and separated into its variables. Finally, we obtain the wave functions and the corresponding energy levels.更多还原
