Delay times for symmetrized and antisymmetrized quantum tunneling configurations

Abstract.

The transit times are obtained for a symmetrized (two identical bosons) and an antisymmetrized (two identical fermions) quantum colliding configuration. Considering two identical particles symmetrically impinging on a one-dimensional barrier, we demonstrate that the phase time and the dwell time give connected results where, however, the exact position of the scattered particles is explicitly determined by the phase time (group delay). For the antisymmetrized wave function configuration, an unusual effect of accelerated transmission is clearly identified in a simultaneous tunneling of two identical fermions.
