Abstract: We calculate fermionic response in domain wall backgrounds of four-dimensional gauged supergravity interpolating between distinct stable anti-de Sitter (AdS) vacua, holographically dual to zero-temperature states of ABJM theory at finite density for monopole charge. The backgrounds were found by Bobev et al. and are similar to zero-temperature limits of holographic superconductors, but with a symmetry-breaking source as well. The condensed scalar mixes charged and neutral fields dual to composite fermionic operators in the top-down Dirac equations. Both gapped and gapless bands of stable quasiparticles are found.
