Query: Nonlinear electric transport in odd-parity magnetic multipole systems:
  Application to Mn-based compounds   Violation of parity symmetry gives rise to various physical phenomena such as
nonlinear transport and cross-correlated responses. In particular, the
nonlinear conductivity has been attracting a lot of attentions in spin-orbit
coupled semiconductors, superconductors, topological materials, and so on. In
this paper we present theoretical study of the nonlinear conductivity in
odd-parity magnetic multipole ordered systems whose $\mathcal{PT}$-symmetry is
essentially distinct from the previously studied acentric systems. Combining
microscopic formulation and symmetry analysis, we classify the nonlinear
responses in the $\mathcal{PT}$-symmetric systems as well as
$\mathcal{T}$-symmetric (non-magnetic) systems, and uncover nonlinear
conductivity unique to the odd-parity magnetic multipole systems. A giant
nonlinear Hall effect, nematicity-assisted dichroism and magnetically-induced
Berry curvature dipole effect are proposed and demonstrated in a model for
Mn-based magnets.
