Quantum phase transition in overdoped La${}_{2-x}$Sr${}_x$CuO${}_4$ evinced by the superfluid density

T. Schneider

The superfluid density of overdoped La${}_{2-x}$Sr${}_x$CuO${}_4$ thin films of high quality have been measured with Tc (defined by the onset of the Meissner effect) from 5.1 to 41.6 K b…
