      abstract     = {We study the chiral separation effect (CSE) in
                      finite-density SU(2) lattice gauge theory with dynamical
                      quarks. We find that the CSE is well described by the free
                      quark result in the high-temperature quark-gluon plasma
                      phase. As one enters the confinement regime with broken
                      chiral symmetry at chemical potential smaller than half of
                      the pion mass, the CSE response is gradually suppressed
                      toward low temperatures in comparison to the free quark
                      result. This suppression can be approximately described by
                      assuming that the CSE current is proportional to the charge
                      density, rather than the chemical potential, as suggested in
                      the literature [Phys. Rev. D 97, 085020 (2018). We also
                      provide an upper bound on the contribution of disconnected
                      fermionic diagrams to the CSE, which is consistent with zero
                      within our statistical errors and small compared to that of
                      the connected diagrams. Our results are obtained mainly in
                      the QCD-like regime of SU(2) gauge theory at low densities,
                      and hence should be at least qualitatively applicable to QCD
                      as well.},
