We present soleakon: nonlinear self-trapped leaky modes displaying particlelike features. A "soleakon" forms when a wave function induces a potential barrier, whose resonant state (leaky mode) corresponds to the wave function itself. We show that, for a proper set of parameters, soleakons are robust and propagate while maintaining their envelope almost indefinitely. However, they eventually disintegrate abruptly. These entities exhibit particlelike interactions behavior, which is nevertheless profoundly different from soliton collisions.
