Interactions and Charge Fractionalization in an Electronic Hong-Ou-Mandel Interferometer
Interactions and Charge Fractionalization in an Electronic Hong-Ou-Mandel Interferometer
We consider an electronic analog of the Hong-Ou-Mandel (HOM) interferometer, where two single electrons travel along opposite chiral edge states and collide at a quantum point contact. Studying the current noise, we show that because of interactions between copropagating edge states, the degree of indistinguishability between the two electron wave …
