In a superconductor with a sublattice degree of freedom, we find unconventional Andreev bound states whose charge density oscillates in sign between the two sublattices. The appearance of these oscillating-charged Andreev bound states is characterized by a Zak phase, rather than a conventional topological invariant. In contrast to conventional Andreev bound states, for oscillating-charged Andreev bound states the proportionality between the electron-like spectral function, the local density of states and the tunneling conductance is broken. We examine the possible appearance of these novel Andreev bound states in UTe$_2$ and locally noncentrosymmetric superconductors. |
