Titre  Nearstationary high energy state in a chiral channel driven out of equilibrium 
Résumé  Ergodic manybody systems are expected to reach quasithermal equilibrium. Here we demonstrate that, surprisingly, highenergy electrons, which are injected into an interacting onedimensional quantum Hall edge mode, stabilize at a farfromthermalized state over a longtime scale. To detect this nonequilibrium state, one positions an energyresolved detector downstream of the point of injection. While in the case of shortranged interactions in multichannel systems the energy distribution generically relaxes to a nearthermal asymptotic state, we here consider a screened interaction of finite range and obtain a different result: the resulting manybody state comprises fastdecaying transient components, followed by a nearly stationary distribution with a peak near the injection energy.
