In recent years, topological photonics inspired by electric topological insulators has
promoted extensive research on robust electromagnetic (EM) wave manipulation and new …

Transistors are key elements of electronic circuits as they enable, for example, the isolation
or amplification of voltage signals. While conventional transistors are point-type (lumped …

We examine a dielectric medium supporting a magnetic current in connection with optical
properties and energy propagation. The dispersion relations, propagating modes, and some …

We theoretically propose how to achieve nonreciprocal enhancement of bipartite and
tripartite entanglement using an optomechanical resonator coupled to a nonlinear optical …

Here, we investigate the nonreciprocal propagation and amplification of surface plasmons in
drift-current biased graphene, using both Galilean and relativistic-type Doppler shift …

Topological photonics has recently emerged as a very general framework for the design of
unidirectional edge waveguides immune to backscattering and deformations, as well as …

This work presents an exploratory study of the potential applications of electrically biased
materials that possess a nonreciprocal and non‐Hermitian electromagnetic response …

Materials with Berry-curvature dipoles support a non-Hermitian electro-optic effect that is
investigated here for lasing at terahertz frequencies. Such a system is conceived here as a …

Motivated by our recent findings in [Phys. Rev. Lett. 128, 013902, 2022], which introduced a
new class of electromagnetic bulk materials whose response is similar to conventional …

Optical nonreciprocity is an essential concept in optical signal processing and
communication. The traditional way to achieve nonreciprocity is using magneto-optical …
