Phys. Rev. Lett. 100, 226805 (2008) [4 pages]N-Particle Scattering Matrix for Electrons Interacting on a Quantum DotReceived 24 October 2007; published 6 June 2008 We present a nonperturbative expression for the scattering matrix of N particles interacting inside a quantum dot. Characterizing the dot by its resonances, we find a compact form for the scattering matrix in a real-time representation. We study the transmission probabilities and interaction-induced orbital entanglement of two electrons incident on the dot in a spin-singlet state. © 2008 The American Physical Society URL:
