Optical analogue of population trapping in the continuum: classical and quantum interference effects
S. Longhi
A quantum theory of light propagation in two optical channel waveguides tunnelling-coupled to a common continuum of modes (such as those of a slab waveguide) is presented, and clas…
Dynamic localization and transport in complex crystals
S. Longhi
The behavior of a Bloch particle in a complex crystal with PT symmetry subjected to a sinusoidal ac force is theoretically investigated. For unbroken PT symmetry and in the single-…
Spectral singularities in a non-Hermitian Friedrichs-Fano-Anderson model
S. Longhi
Spectral singularities are predicted to occur in a non-Hermitian extension of the Friedrichs-Fano-Anderson model describing the decay of a discrete state coupled to a contin…
Spectral singularities and Bragg scattering in complex crystals
S. Longhi
Spectral singularities that spoil the completeness of Bloch-Floquet states may occur in non-Hermitian Hamiltonians with complex periodic potentials. Here an equivalence is establis…
