Symmetry restoration through chaotic hysteresis in a non-Hermitian optical trimer
Johanne Hizanidis, Konstantinos G. Makris
We investigate symmetry restoration and spatially localized dynamics in a non-Hermitian optical trimer composed of three lossy waveguides with complex-valued couplings. Extending o…
Non-Hermitian off-diagonal disordered optical lattices
E. T. Kokkinakis, I. Komis, K. G. Makris +1
Within the framework of non-Hermitian photonics, we investigate the spectral and dynamical properties of one- and two-dimensional non-Hermitian off-diagonal disordered optical latt…
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…
