Phys. Rev. B 55, 13726–13729 (1997)Electron scattering through a quantum dot: A phase lapse mechanismReceived 20 January 1997; published in the issue dated 15 May 1997 The scattering phase shift of an electron transferred through a quantum dot is studied within a model Hamiltonian, accounting for both the electron-electron interaction in the dot and a finite temperature. It is shown that, unlike in an independent electron picture, this phase may exhibit a phase lapse of π between consecutive resonances under generic circumstances. © 1997 The American Physical Society URL:
