Quantum Mechanics of a Photon
Hassan Babaei, Ali Mostafazadeh
A first quantized free photon is a complex massless vector field whose field strength satisfies Maxwell's equations in vacuum. We construct the Hilbert space $\mathscr{H}…
Spectral Singularities in the TE and TM modes of a PT-Symmetric Slab System: Optimal conditions for realizing a CPA-Laser
Ali Mostafazadeh, Mustafa Sarisaman
Among the interesting outcomes of the study of the physical applications of spectral singularities in PT-symmetric optical systems is the discovery of CPA-lasers. These are devices…
Dynamical Theory of Scattering, Exact Unidirectional Invisibility, and Truncated potential
Ali Mostafazadeh
The dynamical formulation of time-independent scattering theory that is developed in [Ann. Phys. (NY) 341, 77-85 (2014)] offers simple formulas for the reflection and transmission…
Unidirectional Invisibility and Nonreciprocal Transmission in Two and Three Dimensions
Farhang Loran, Ali Mostafazadeh
We explore the phenomenon of unidirectional invisibility in two dimensions, examine its optical realizations, and discuss its three-dimensional generalization. In particular we con…
