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.…
Defect-driven incoherent skin localization
Emmanouil T. Kokkinakis, Konstantinos G. Makris, Eleftherios N. Economou
The process of dephasing during wave evolution has traditionally been viewed as an obstacle to localization, leading to diffusion even in strongly disordered Hermitian lattices. In…
Self-trapping and skin solitons in two-dimensional non-Hermitian lattices
Emmanouil T. Kokkinakis, Ioannis Komis, Konstantinos G. Makris
Two-dimensional non-Hermitian photonic lattices with asymmetric couplings offer rich possibilities for controlling wave localization, through the emergence of the non-Hermitian ski…
Dephasing-induced jumps in non-Hermitian disordered lattices
Emmanouil T. Kokkinakis, Konstantinos G. Makris, Eleftherios N. Economou
Changes in the wavefunction's phase during propagation in a random Hermitian lattice, a process known as dephasing, results in diffusion rather than Anderson localization. However,…
Anderson localization versus hopping asymmetry in a disordered lattice
E. T. Kokkinakis, K. G. Makris, E. N. Economou
In the framework of non-Hermitian photonics, we investigate the interplay between disorder and non-Hermiticity in a one-dimensional Hatano-Nelson lattice. While Anderson localizati…
Tuneable entangled photon pair generation in a liquid crystal
Vitaliy Sultanov, Aljaž Kavčič, Emmanuil Kokkinakis +3
Liquid crystals, with their ability of self-assembly, strong response to the electric field, and integrability into complex systems, are key materials in light beam manipulation. R…
