  We investigate the effects of the chiral MIT boundary conditions for a Dirac
particle in a 1D 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.
