چکیده
Hybrid quantum systems have attracted much attention due to the fact that they combine advantages of different physical subsystems. Cavity QED (cavity electrodynamics) with magnons is a hybrid combines YIG (Yttrium Iron Garnet) sphere and 3D (three-dimensional) rectangular microwave cavity. Based on this photon-magnon system, we obtain an approximate analytic solution by RWA (rotating wave approximation) ingenious transformation. After skillfully diagonalizing Hamiltonian, show Kerr-nonlinearity interactions could yield negativity value Wigner function, periodic quadrature squeezing effects, antibunching property, field nonclassicality in magnon. Our work may stimulate study coupling its potential applications information processing.

Dependence of enhanced Kerr nonlinearity on coupling power in a three-level atomic system.
We study the enhanced Kerr-nonlinear coefficient in a three-level A-type atomic system for various coupling-beam powers. The Kerr-nonlinear coefficient behaves very differently in the strong and the weak coupling power regions and changes sign when the coupling or probe frequency detuning changes sign. Comparisons of Kerr-nonlinear coefficients as functions of probe frequency detuning, coupling...
متن کاملMagnon damping by magnon-phonon coupling in manganese perovskites
Inelastic neutron scattering was used to systematically investigate the spin-wave excitations ~magnons! in ferromagnetic manganese perovskites. In spite of the large differences in the Curie temperatures (TC’s! of different manganites, their low-temperature spin waves have very similar dispersions with the zone-boundary magnon softening and broadening that cannot be explained by the canonical d...
متن کاملComplete quantum teleportation with a kerr nonlinearity
We present a scheme for the quantum teleportation of the polarization state of a photon employing a cross-Kerr medium. The experimental feasibility of the scheme is discussed and we show that, using the recently demonstrated ultraslow light propagation in cold atomic media, our proposal can be realized with presently available technology.
متن کاملCavity magnomechanics
A dielectric body couples with electromagnetic fields through radiation pressure and electrostrictive forces, which mediate phonon-photon coupling in cavity optomechanics. In a magnetic medium, according to the Korteweg-Helmholtz formula, which describes the electromagnetic force density acting on a medium, magneostrictive forces should arise and lead to phonon-magnon interaction. We report suc...
