Query: Electrostatically tuned quantum superconductor-metal-insulator
  transition at the LaAlO3/SrTiO3 interface   Recently superconductivity at the interface between the insulators LaAlO3 and
SrTiO3 has been tuned with the electric field effect to an unprecedented range
of transition temperatures. Here we perform a detailed finite size scaling
analysis to explore the compatibility of the phase transition line with
Berezinskii-Kosterlitz-Thouless (BKT) behavior and a 2D-quantum
phase(QP)-transition. In an intermediate regime, limited by a gate voltage
dependent limiting length, we uncover remarkable consistency with a
BKT-critical line ending at a metallic quantum critical point, separating a
weakly localized insulator from the superconducting phase. Our estimates for
the critical exponents of the 2D-QP-transition, z=1 and nu=0.66, suggest that
it belongs to the 3D-xy universality class.
