Asymmetric Perfect Absorption and Lasing of Nonlinear Waves by a Complex <i>δ</i>-Potential
Spectral singularities and coherent perfect absorption are two interrelated concepts that have originally been introduced and studied for linear waves interacting with complex potentials. In the meantime, the distinctive asymptotic behavior of perfectly absorbed waves suggests considering possible g...
