- Title: Partition of Two Interacting Electrons by a Potential Barrier
- Authors: Sungguen Ryu and H.-S. Sim
- Abstract summary: We theoretically study the partition and collision of two interacting hot electrons at a potential barrier in the quantum Hall regime.
We predict their kinetic energy change by their Coulomb interaction during the scattering delay time inside the barrier.
The energy change results in characteristic deviation of the partition probabilities from the noninteracting case.

- Abstract: Scattering or tunneling of an electron at a potential barrier is a
fundamental quantum effect. Electron-electron interactions often affect the
scattering, and understanding of the interaction effect is crucial in detection
of various phenomena of electron transport and their application to electron
quantum optics. We theoretically study the partition and collision of two
interacting hot electrons at a potential barrier in the quantum Hall regime. We
predict their kinetic energy change by their Coulomb interaction during the
scattering delay time inside the barrier. The energy change results in
characteristic deviation of the partition probabilities from the noninteracting
case. The derivation includes nonmonotonic dependence of the probabilities on
the barrier height, which agrees with recent experiments, and reduction of the
fermionic antibunching.

We report the existence of a sizeable quantum tunnelling splitting between the two lowest electronic spin levels of mononuclear Ni complexes.
The level anti-crossing, or magnetic clock transition, associated with this gap has been directly monitored by heat capacity experiments.
The comparison of these results with those obtained for a Co derivative, for which tunnelling is forbidden by symmetry, shows that the clock transition leads to an effective suppression of intermolecular spin-spin interactions.
