Query: Fermi Surface reconstruction and anomalous low temperature resistivity
  in electron-doped La2-xCexCuO4   We report ab-plane Hall Effect and magnetoresistivity measurements on
La2-xCexCuO4 thin films as a function of doping for magnetic fields up to 14T
and temperatures down to 1.8K. A dramatic change in the low temperature (1.8 K)
normal state Hall coefficient is found near a doping Ce=0.14. This, along with
a nonlinear Hall resistance as a function of magnetic field, suggests that the
Fermi surface reconstructs at a critical doping of Ce= 0.14. A competing
antiferromagnetic phase is the likely cause of this Fermi surface
reconstruction. Low temperature linear-in-T resistivity is found at Ce=0.14,
but anomalously, also at higher doping. We compare our data with similar
behavior found in hole-doped cuprates at a doping where the pseudogap ends
