Grid-state deformation in a no-jump non-Hermitian bosonic dimer
B. M. Rodriguez-Lara, H. Ghaemi-Dizicheh, S. Dehdashti +3
We study the no-jump evolution of ideal grid states in a lossy bosonic dimer with differential decay. The effective non-Hermitian quadratic dynamics induces a complex symplectic fl…
Non-Hermitian three-mode couplers
B. M. Rodriguez-Lara, H. Ghaemi-Dizicheh, S. Dehdashti +3
Photonic systems with exceptional points, where eigenvalues and corresponding eigenstates coalesce, have attracted interest due to their topological features and enhanced sensitivi…
Higher-order exceptional points in a non-reciprocal waveguide beam splitter
Hamed Ghaemi-Dizicheh, Shahram Dehdashti, Andreas Hanke +2
Non-Hermitian systems have attracted significant interest because of their intriguing and useful properties, including exceptional points (EPs), where eigenvalues and the correspon…
A class of stable nonlinear non-Hermitian skin modes
Hamed Ghaemi-Dizicheh
The non-Hermitian skin effect (NHSE) is a well-known phenomenon in open topological systems that causes a large number of eigenstates to become localized at the boundary. Although…
