  In this Reply we argue that (i) the Hamiltonian, Eq. (17) in our paper (Phys.
Rev. Lett. 108, 070405 (2012)), is definitely Lorentz invariant; (ii) the
conditions of generating topological Aharonov-Casher(AC) and Scalar
Aharonov-Bohm (SAB) effects are essential and physically meaningful; (iii) the
Hamiltonians both in Phys. Rev. Lett. 74, 2847 (1995) and arXiv:1311.4011 are
not suitable to describe the polarized spinor particles.
