Nonreciprocal Macroscopic Entanglement through Magnon Squeezing in a Cavity Magnomechanics

Abderrahim El Allati, Ilkay Demir, Khadija El Anouz, Ziyad Imara

Reversing the squeezing phase of magnons produces two distinct configurations for nonreciprocal entanglement among magnons, photons, and phonons.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

Reversing the squeezing phase, namely theta -> theta + pi, reverses the frequency shift and the effective dissipation rate simultaneously, producing two experimentally distinct configurations that enable nonreciprocal entanglement.

C2weakest assumption

Precise experimental control of both the amplitude and phase of the squeezed magnon mode is achievable while the system remains accurately described by the standard cavity-magnon-phonon Hamiltonian with added squeezing term.

C3one line summary

A theoretical scheme uses magnon squeezing phase reversal to achieve tunable nonreciprocal macroscopic entanglement in a magnon-photon-phonon hybrid system.
