Query: Thermoelectric transport in a correlated electron system on the surface
  of liquid helium   We report on the direct observation of the thermoelectric transport in a
nondegenerate correlated electron system formed on the surface of liquid
helium. We find that the microwave-induced excitation of the vertical
transitions of electrons between the surface-bound states leads to their
lateral flow, which we were able to detect by employing a segmented electrode
configuration. We show that this flow of electrons arises due to the Seebeck
effect, thus our method provides a new tool to study thermoelectricity in a
disorder-free correlated electron system. Our experimental results are in good
agreement with the theoretical calculations based on kinetic equations, with
proper account of fast electron-electron collisions.
