Coherent perfect absorber and laser for nonlinear waves in optical waveguide arrays
Dmitry A. Zezyulin, Herwig Ott, Vladimir V. Konotop
A localized non-Hermitian potential can operate as a coherent perfect absorber or as a laser for nonlinear waves. The effect is illustrated for an array of optical waveguides, with…
Coherent perfect absorption of nonlinear matter waves
Andreas Müllers, Bodhaditya Santra, Christian Baals +6
Coherent perfect absorption is the complete extinction of incoming radiation by a complex potential in a physical system supporting wave propagation. The concept was proven for lin…
Nonlinear standing waves in an array of coherently coupled Bose-Einstein condensates
Christian Baals, Herwig Ott, Joachim Brand +1
Stationary solitary waves are studied in an array of linearly-coupled one-dimensional Bose-Einstein condensates (BECs) by means of the Gross-Pitaevskii equation. Solitary wave…
Photoassociation of rovibrational Rydberg molecules
O. Thomas, C. Lippe, T. Eichert +1
In this work we discuss the rotational structure of Rydberg molecules. We calculate the complete wave function in a laboratory fixed frame and derive the transition matrix elements…
