Query: Voltage controllable superconducting state in the multi-terminal
  superconductor-normal metal bridge   We study voltage controllable superconducting state in multi-terminal bridge
composed of the dirty superconductor/pure normal metal (SN) bilayer and pure
normal metal. In the proposed system small control current $I_{ctrl}$ flows via
normal bridge, creates voltage drop $V$ and modifies distribution function of
electrons in connected SN bilayer. In case of long normal bridge the voltage
induced nonequilibrium effects could be interpreted in terms of increased local
electron temperature. In this limit we experimentally find large sensitivity of
critical curent $I_c$ of Cu/MoN/Pt-Cu bridge to $I_{ctrl}$ and relatively large
current gain which originate from steep dependence of $I_c$ on temperature and
large $I_c$ (comparable with theoretical depairing current of superconducting
bridge). In the short normal bridge deviation from equilibrium cannot be
described by simple increase of local temperature but we also theoretically
find large sensitivity of $I_c$ to control current/voltage. In this limit we
predict existence at finite $V$ of so called in-plane Fulde-Ferrell state with
spontaneous currents in SN bilayer. We argue that its appearance is connected
with voltage induced paramagnetic response in N layer.
