 abstract = {Using inhomogeneous dynamical mean-field theory, we show that the
normal-metal proximity effect could force any finite number of
Mott-insulating ``barrier'' planes sandwiched between semi-infinite
metallic leads to become ``fragile'' Fermi liquids. They are fully
Fermi-liquid-like at T = 0, leading to a restoration of lattice
periodicity at zero frequency, with a well-defined Fermi surface, and
perfect (ballistic) conductivity. However, the Fermi-liquid character
can rapidly disappear at finite omega, V, T, disorder, or magnetism, all
of which restore the expected quantum tunneling regime, leading to
fascinating possibilities for nonlinear response in devices.},
