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,…
Diffraction and pseudospectra in non-Hermitian quasiperiodic lattices
Ananya Ghatak, Dimitrios H. Kaltsas, Manas Kulkarni +1
Wave dynamics in disordered open media is an intriguing topic, and has lately attracted a lot of attention in non-Hermitian physics, especially in photonics. In fact, spatial distr…
Scaling of pseudospectra in exponentially sensitive lattices
Ioannis Kiorpelidis, Konstantinos G. Makris
One of the important features of non-Hermitian Hamiltonians is the existence of a unique type of singularities, the so-called exceptional points (EPs). When the corresponding syste…
Nonlinear dynamics and chaos in dissipative optical trimers with complex couplings
Johanne Hizanidis, Konstantinos G. Makris
In the context of non-Hermitian photonics, we consider a nonlinear optical trimer with three lossy waveguides with complex couplings. This non-Hermitian trimer exhibits stable stat…
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…
