Extended Data Fig. 4: Dependence of transmission thresholds and partitioning on interarrival time.
From: Two electrons interacting at a mesoscopic beam splitter

Illustration of the Δt dependence of the transmission thresholds \({\epsilon }_{i}^{* }({\epsilon }_{3-i}^{},{{\Delta }}t)\) and joint probability distribution in the partitioning diagram for 〈ϵ1〉 = 〈Δt〉 = 0 with (a) Δt = − 10 ps and (b) Δt = + 10 ps. (c) Alternative presentation of the partitioning diagram in terms of scaled coordinates corresponding to the phase diagram of two-electron partitioning as introduced in ref. 35. The contour line marks the coverage factor k = 1 of the full joint probability distribution of the scaled coordinates for the most symmetric tuning, 〈ϵ1〉 = 〈Δt〉 = 0. In the scaled coordinates the partitioning domain boundaries are independent of Δt while the joint probability distribution is stretched along the horizontal and vertical axis, as at large ∣Δt∣ electrons in most pairs never approach each other close enough for sufficiently strong interaction.
