Phase Transitions and Topological Protection in Anyonic-PT-Symmetric Lattices
Ruiying Zhang, Ziteng Wang, Daohong Song +3
Parity-time (PT) symmetry and anti-PT symmetry have attracted extensive interest for their non-Hermitian spectral properties, particularly the emergence of purely real and imaginar…
Optical Tautochrone and Squeezing Dynamics in Nonuniform Lattices
Ioannis Kiorpelidis, Matthias Heinrich, Alexander Szameit +2
We present exact analogies between the tautochrone problem of classical mechanics and the squeezed states of quantum optics to optical lattices. Both phenomena emerge in the same p…
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,…
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…
Robustness versus sensitivity in non-Hermitian topological lattices probed by pseudospectra
I. Komis, D. Kaltsas, S. Xia +3
Non-Hermitian topological systems simultaneously posses two antagonistic features: ultra sensitivity due to exceptional points and robustness of topological zero energy modes, and…
Spectral method for efficient computation of time-dependent phenomena in complex lasers
O. Malik, K. G. Makris, H. E. Türeci
Studying time-dependent behavior in lasers is analytically difficult due to the saturating non-linearity inherent in the Maxwell-Bloch equations and numerically demanding because o…
