Evening out the spin and charge parity to increase $${T}_{c}$$ Tc in $${{\\rm{Sr}}}_{2}{{\\rm{RuO}}}_{4}$$ Sr2RuO4

Abstract

The mechanism behind unconventional superconductivity in Sr2RuO4 is still not fully understood and results from a complex interplay between spin, charge and orbital degrees of freedom. The authors develop a parameter-free theoretical approach and demonstrate that the superconductivity exhibits both singlet and triplet components the relative strength of which is dependent on the interplay between the spin and charge fluctuations and can be controlled by strain.
