Abstract Recently the field of cavity magnonics, a field focused on controlling the interaction between magnons and photons confined within microwave resonators, has drawn significant attention as it offers a platform for enabling advancements in qua

Bound states in continuum (BICs) are states of a system possessing significantly large lifetimes with applications across various branches of science. In this work, we propose an expedient protocol to engineer BICs using the Kerr nonlinearities of a

Cavity-mediated magnon-magnon coupling can lead to a transfer of spin-wave excitations between two spatially separated magnetic samples. We enunciate how the application of a two-photon parametric drive to the cavity can lead to stark amplification i

Cavity-mediated coupling can lead to remote exchange of energy between two spatially separated bosonic modes. Here, we demonstrate how the application of a two-photon parametric drive to the cavity can bring about a prodigious enhancement in this tra

The intrinsic dissipation of systems into a shared reservoir introduces coherence between two systems, enabling anti-Parity-Time (anti-PT) symmetry. In this paper, we propose an anti-PT symmetric converter, consisting of a microwave cavity coupled di

The prospect of a system possessing two or more stable states for a given excitation condition is of topical interest with applications in information processing networks. In this work, we establish the remote transfer of bistability from a nonlinear

In the last few years, the great utility of PT-symmetric systems in sensing small perturbations has been recognized. Here, we propose an alternate method relevant to dissipative systems, especially those coupled to the vacuum of the electromagnetic f

We present a novel scheme to generate an entangled pair of yttrium iron garnet (YIG) samples in a cavity system which does not involve any nonlinearities. The generated macroscopic entanglement can survive up to 500mK.

The cavity mediated spin current between two ferrite samples has been reported by Bai et. al. [Phys. Rev. Lett. 118, 217201 (2017)]. This experiment was done in the linear regime of the interaction in the presence of external drive. In the current pa

We show how to generate an entangled pair of yttrium iron garnet (YIG) samples in a cavity-magnon system without using any nonlinearities which are typically very weak. This is against the conventional wisdom which necessarily requires strong Kerr li
