Statistics of resonances in one-dimensional continuous systems

Research output: Contribution to journalArticlepeer-review


We study the average density of resonances (DOR) of a disordered one- dimensional continuous open system. The disordered system is semi-infinite, with white-noise random potential, and it is coupled to the external world by a semi-infinite continuous perfect lead. Our main result is an integral representation for the DOR which involves the probability density function of the logarithmic derivative of the wave function at thecontact point.
