• Abstract summary: microwave-induced excitation of the vertical transitions of electrons between the surface-bound states leads to their lateral flow. 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.

• Abstract: 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.

• Coulomb interaction-driven entanglement of electrons on helium [0.0]
  We theoretically investigate the generation of emphmotional entanglement between two electrons via their unscreened Coulomb interaction. We compute the motional energy spectra of the electrons, as well as their entanglement, by diagonalizing the model Hamiltonian with respect to a single-particle Hartree product basis. In particular, the theoretical tools developed here can be used for fine tuning and optimization of control parameters in future experiments with electrons trapped above the surface of superfluid helium or solid neon.
