Title 



Violation of Onsager symmetry for a ballistic channel Coulomb coupled to a quantum ring

Abstract 



We investigate a scattering of electron which is injected individually into an empty ballistic channel containing a cavity that is Coulomb coupled to a quantum ring charged with a single electron. We solve the timedependent Schrödinger equation for the electron pair with an exact account for the electronelectron correlation. Absorption of energy and angular momentum by the quantum ring is not an even function of the external magnetic field. As a consequence we find that the electron backscattering probability is asymmetric in the magnetic field and thus violates Onsager symmetry.
