Unusual behavior of Superfluid Density of Overdoped Cuprates

We theoretically study the superfluid density of overdoped cuprate superconductors within a t-J like model. We show that the temperature dependence of the superfluid density on the overdoped side has very unusual features. We explain the physical origins of this behavior, and show that this can be used to understand the recent experimental results of Bozovic et. al. [Nature 536, 309 (2016)].
