      abstract     = {We present a new leptogenesis mechanism based on the
                      standard type-I seesaw model that successfully operates at
                      right-handed-neutrino masses as low as a few 100 TeV. This
                      mechanism, which we dub 'wash-in leptogenesis', does not
                      require any CP violation in the neutrino sector and can be
                      implemented even in the regime of strong washout. The key
                      idea behind wash-in leptogenesis is to generalize standard
                      freeze-out leptogenesis to a nonminimal cosmological
                      background in which the chemical potentials of all particles
                      not in chemical equilibrium at the temperature of
                      leptogenesis are allowed to take arbitrary values. This sets
                      the stage for building a plethora of new baryogenesis models
                      where chemical potentials generated at high temperatures are
                      reprocessed to generate a nonvanishing B-L asymmetry at low
                      temperatures. As concrete examples, we discuss wash-in
                      leptogenesis after axion inflation and in the context of
                      grand unification.},
