Charge stripe manipulation of superconducting pairing symmetry transition.

ABSTRACT: Charge stripes have been widely observed in many different types of unconventional superconductors, holding varying periods ( P ) and intensities. However, a general understanding on the interplay between charge stripes and superconducting properties is still incomplete. Here, using large-scale unbiased numerical simulations on a general inhomogeneous Hubbard model, we discover that the charge-stripe period P , which is variable in different real material systems, could dictate the pairing symmetries-d wave for P≥4,s and d waves for P≤3 . In the latter, tuning hole doping and charge-stripe amplitude can trigger a d-s wave transition and magnetic-correlation shift, where the d-wave state converts to a pairing-density wave state, competing with the s wave. These interesting phenomena arise f
