We use a simplified model of electrons weakly coupled to a single phonon frequency ω E, but assume that the energy gap Δ does not have any isotope effect. Nevertheless, we find an isotope effect for n S/m* which is significant if Δ is sufficiently large that it becomes comparable to ω E, a regime of interest to high-T c cuprate superconductors and possibly other families of unconventional superconductors with relatively high T c. Our model is too simple to describe the cuprates and it gives the wrong sign of the isotope effect when compared with experiment, but it is a proof of principle that the isotope effect exists for n S/m* in materials where the pairing gap and T c are not of phonon origin and have no isotope effect.","lang":"eng"}],"doi":"10.1103/PhysRevB.83.024506","publist_id":"6434","date_created":"2018-12-11T11:49:28Z","author":[{"first_name":"Maksym","id":"47809E7E-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-2399-5827","last_name":"Serbyn","full_name":"Maksym Serbyn"},{"first_name":"Patrick","full_name":"Lee, Patrick","last_name":"Lee"}],"month":"01","title":"Isotope effect on the superfluid density in conventional and high-temperature superconductors","intvolume":"        83","extern":1}
