Query: Probing the magnetoelectric effect in noncentrosymmetric superconductors
  by equal-spin Andreev tunneling   In noncentrosymmetric superconductors (NCSs), the conversion of a charge
current into spin magnetization - the so called magnetoelectric effect - is the
direct indicator of the unconventional, mixed-parity order parameter. This
paper proposes a scheme to detect the magnetoelectric effect by anomalous,
equal-spin Andreev tunneling in NCS/ferromagnet contacts. The proposal relies
on the ability to generate spin-polarized triplet pairing by passing an
electric current through an NCS. Such an induced triplet pairing bears a
similarity to the paradigmatic nonunitary pairing in triplet superfluids with a
complex vector order parameter ${\bf d}$. The qualitative difference is that
the induced nonunitary state can be realised in NCSs with a purely real ${\bf
d}$ by breaking the time-reversal symmetry in current-biased setups. This
offers a possibility to access the unconventional superconductivity in NCSs
through electrical transport measurements.
