We theoretically investigate a Hong-Ou-Mandel like setup as a tool to probe it. Collisions of two electrons with the same spin show a Pauli dip, analogous to the one obtained in the integer quantum Hall case. Moreover, the collisions between electrons of opposite spin also lead to a dip, known as $\\mathbb{Z}_{2}$ dip, which is a direct consequence of the constraints imposed by time-re","authors_text":"C.
