Abstract

We study the average density of resonances, <ρ(x,y)><\rho(x,y)>, in a semi-infinite disordered chain coupled to a perfect lead. The function <ρ(x,y)><\rho(x,y)> is defined in the complex energy plane and the distance yy from the real axes determines the resonance width. We concentrate on strong disorder and derive the asymptotic behavior of <ρ(x,y)><\rho(x,y)> in the limit of small yy.
