Distribution of zeros of theS-matrix of chaotic cavities with localized losses and coherent perfect absorption: non-perturbative results

Year: 2017

Type: article

Abstract: We employ the random matrix theory framework to calculate the density of zeroes of an M -channel scattering matrix describing a chaotic cavity with a single localized absorber embedded in it. Our approach extends beyond the weak-coupling limit of the cavity with the channels and applies for any absorption strength. Importantly it provides an insight for the optimal amount of loss needed to realize a chaotic coherent perfect absorbing trap. Our predictions are tested against simulations for two types of traps: a complex network of resonators and quantum graphs.
