Query: Strongly parity-mixed superconductivity in Rashba-Hubbard model   Heterostructures containing strongly correlated electron systems provide a
platform to clarify interplay of electron correlation and Rashba spin-orbit
coupling in unconventional superconductors. Motivated by recent fabrication of
artificially-engineered heavy fermion superlattices and high-temperature
cuprate superconductors, we conduct a thorough study on superconductivity in
Rashba-Hubbard model. In contrast to previous weak coupling approaches, we
employ fluctuation-exchange approximation to describe quantum critical magnetic
fluctuations and resulting superconductivity. As a result, robust Fermi
surfaces against magnetic fluctuations, incommensurate spin fluctuations, and a
strongly parity-mixed superconducting phase are demonstrated in a wide range of
electron filling from type-II van Hove singularity to half-filling. We also
clarify impacts of type-II van Hove singularity on magnetic fluctuations and
superconductivity. Whereas the $d_{x^2-y^2}$-wave pairing always dominant,
subdominant spin-triplet pairing with either $p$-wave or $f$-wave symmetry
shows a comparable magnitude, especially near the type-II van Hove singularity.
Our results resolve unsettled issues on strongly correlated Rashba systems and
uncover candidate systems of nonreciprocal transport and topological
superconductivity.
