Electron scattering through a quantum dot: A phase lapse mechanism
Electron scattering through a quantum dot: A phase lapse mechanism
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 \ensuremath{\pi} …
