Optimizing mixing in the Rudner-Levitov lattice

I. Peshko, M. Antsukh, D. Novitsky +1

Here we discuss optimization of mixing in finite linear and circular Rudner-Levitov lattices, i.e., Su-Schrieffer-Heeger lattices with a dissipative sublattice. We show that presen…

Virtual perfect absorption in resonant media and their PT-symmetric generalizations

Denis Novitsky, Alexander Shalin

Virtual perfect absorption (VPA) is an effect simulating real absorption of light by using excitation at a complex frequency corresponding to a scattering zero. We theoretically st…

Tunable virtual gain in resonantly absorbing media

Denis Novitsky

Virtual gain refers to the simulation of real light amplification using radiation with exponentially decaying amplitude, so that its complex frequency corresponds to the scattering…

Wigner time for electromagnetic radiation in plasma

Sergey Gaponenko, Denis Novitsky

Wave tunneling is an intriguing phenomenon spanning different branches of physics, from quantum mechanics to classical electrodynamics and optics. The Wigner (or phase) time is pro…

CPA-lasing associated with the quasibound states in the continuum in asymmetric non-Hermitian structures

Denis V. Novitsky, Adia Canos Valero, Alexander Krotov +3

Non-Hermitian photonic systems with loss and gain attract much attention due to their exceptional abilities in molding the flow of light. Introducing asymmetry to the $\mathcal{PT}…

Trapped-mode excitation in all-dielectric metamaterials with loss and gain

Anton V. Hlushchenko, Denis V. Novitsky, Vladimir R. Tuz

Non-Hermitian photonics based on combining loss and gain media within a single optical system provides a number of approaches to control and generate the flow of light. In this pap…
