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…
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…
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…
