Effects of chiral MIT boundary conditions for Dirac particle in a box.

We investigate the effects of the chiral MIT boundary conditions for a Dirac particle in a one-dimensional box. We show how the boundary condition affects the discrete momentum, energy level, transition frequency, and spin state in a box. The effects of the chiral MIT boundary conditions on the probability and scalar densities are also demonstrated. The results show that an asymmetric distribution appears in the box depending on the parameters of the spin orientation and chiral angle.
