In a reciprocal medium, transmission of electromagnetic (EM) waves is symmetric along
opposite directions which restrict design and implementation of various systems in optics …

We propose an experimentally realizable nonreciprocal magnonic device at the single-
magnon level by exploiting magnon blockade in a magnon-based hybrid system. The …

Cavity optomechanics, a promising platform to investigate macroscopic quantum effects, has
