Title: Tuning electron-electron correlation in noncentrosymmetric superconductor BiPd

In this work, we have successfully tuned the electron-electron correlation in new noncentrosymmertic superconductor (NCS) BiPd via Pb substitution on one of the inequivalent Bi sites present in BiPd and simultaneously keeping the parent noncentrosymmetric crystal structure intact. Heat capacity data is suggesting a fourfold increase in density of states at Fermi level via Pb substitution while superconducting transition temperature has been suppressed. This work will clearly open up a rare chance to study the effect of electron–electron correlation via selective tuning of DOS at Fermi level in NCS.
