Evolving disorder in non-Hermitian lattices
I. Komis, E. T. Kokkinakis, K. G. Makris +1
The impact of disorder on wave transport has been extensively studied in Hermitian systems, where static randomness gives rise to Anderson localization. In non-Hermitian lattices,…
Non-Hermitian impurity problem
E. T. Kokkinakis, I. Komis, K. G. Makris +1
The problem of a single Hermitian impurity has long served as a cornerstone in condensed matter physics, offering fundamental insights into the mechanisms of Anderson localization.…
Effect of imaginary gauge on wave transport in driven-dissipative systems
I. Komis, K. G. Makris, K. Busch +1
Wave transport in disordered media is a fundamental problem with direct implications in condensed matter, materials science, optics, atomic physics, and even biology. The majority…
Shape-preserving beam transmission through non-Hermitian disordered lattices
A. F. Tzortzakakis, K. G. Makris, S. Rotter +1
We investigate the propagation of Gaussian beams through optical waveguide lattices characterized by correlated non-Hermitian disorder. In the framework of coupled mode theory, we…
