“…[1][2][3][4][5][6][7][8][9] The interest in these band gaps is related to the potential applications of magnon-transport devices and is supported by the advanced progress in nanofabrication technology. 10 Two-dimensional ͑2D͒ and three-dimensional ͑3D͒ composite systems constituted by periodic inclusions of at least two magnetic materials in a host matrix can exhibit an absolute magnonic band gap where the propagation of spin waves is inhibited in any direction of the space.…”

“…The phase and group velocities of spin waves are also functions of the structure size and the applied external field and may vary over a wide range. 1 In addition to the band gaps, a great interest has been paid to the so-called Fano resonances that may be introduced in such gaps. Some analytical models, in phononic band-gap crystals, have been proposed to explain the origin and the behavior of such resonances.…”

Evidence of Fano-like resonances in mono-mode magnetic circuits

et al. 2008

In the frame of long-wavelength Heisenberg model, a simple magnonic device is designed to obtain possibly transmission stop bands ͑where the propagation of spin waves is forbidden͒. This simple device is composed of an infinite one-dimensional mono-mode waveguide ͑the backbone͒ along which N͑NЈ͒ side resonators are grafted at two sites. Contrary to all known systems of this kind, a spectral transmission gap of nonzero width occurs here even with this simple structure. This is obtained by combining appropriately the zeros of transmission of the side resonators. Sharp resonant states inside the gaps can be achieved without introducing any defects in the structure. This results from an internal resonance of the structure when such a resonance is situated in the vicinity of a zero of transmission or placed between two zeros of transmission, the so-called Fano resonances. A general analytical expression for the transmission coefficient is given for various systems of this kind within the framework of the Green's function method. The amplitude, the phase, and the phase time of the transmission are discussed as a function of frequency and it is shown that the width of the stop bands is very sensitive to the number of the side resonators. These results should have important consequences for designing integrated devices such as narrow-frequency optical or microwave filters and high-speed switches.

“…states with strong positionmomentum correlations may lead to greater transparency of the Coulomb barrier during the interaction of charged particles. This is quite relevant, for instance, in the astrophysics of stars and in controlled nuclear fusion, where the action of the Coulomb barrier leads to a very low tunneling probability for low-energy particles [1]. For Gaussian states (which include coherent, squeezed and thermal states), the RSUP constitutes the necessary and sufficient condition of quantumness.…”

“…Experimentally, coherent and squeezed states play an important role in quantum optics [3], quantum computation of continuous variables [4] and investigations of the quantum-classical transition [5]. Finally, the RSUP is invariant under linear symplectic transformations, a property which is not shared by inequality (1). This is important in the context of semi-classical analysis [5] and in the search for directions of minimal uncertainty [6].…”

In this work we derive a matrix formulation of a noise-disturbance uncertainty relation, which is akin to the Robertson-Schrödinger uncertainty principle. Our inequality is stronger than Ozawa's uncertainty principle and takes noise-disturbance correlations into account. Moreover, we show that, for certain types of measurement interactions, it is covariant with respect to linear symplectic transformations of the noise and disturbance operators.

“…Magnetostatic waves can be considered as a simple type of spin waves, when the inhomogeneous exchange interaction can be neglected. The observed complexity rise of the spectra of the MSW with the complication of the structure of the films [3,4], apparently, indicates the need for a more detailed theoretical investigations of the fundamental properties of the MSW. Research conditions limiting the range of MSW with high frequencies may be important.…”

Abstract. Surface waves in thin isotropic ferromagnet slab magnetized in its plane are considered in the magnetostatic limit. Magnetostatic waves are considered as a type of spin waves. The special attention is given to the propagation directions of the waves, which are not orthogonal and parallel to the magnetization of the film. Two features of these waves have not been discussed earlier: the wave resonance with orientation and the existence of a new type of the surface magnetostatic waves. The position of the resonance peak depends not only on the frequency, but also on the direction of wave propagation, and we use the term "wave resonance with orientation". The wave resonance with orientation predicted theoretically on the basis of the dispersion relation of Damon-Eshbach
