The time evolution of even and odd squeezed states, as well as that of squeezed number states, has been given in simple, analytic form. This follows experimental work on trapped ions which has demonstrated even and odd coherent states, number states, and squeezed (but not displaced) ground states. We review this situation and consider the extension to even and odd squeezed number states. Questi...

A low Gilbert damping factor is crucial for emerging magneto-acoustic devices. In current work, angle-dependent and temperature-dependent of magnetostrictive FeCoSiB thin films have been investigated using electron spin resonance (ESR) vector network analyzer ferromagnetic (VNA-FMR) techniques, respectively. very ∼0.0038 was measured with in-plane magnetic fields at room temperature. Temperatur...

We investigate ideal and non-ideal continuous-variable quantum teleportation protocols realized by using an entangled displaced Fock state resource. The characteristic function formulation is applied to measure the relative performance of for teleporting squeezed coherent states. It found that such single-mode input fields, average fidelity remains at classical threshold, suggesting states are ...

we study entanglement and squeezing of a cluster of spin systems under the influence of the two-axis countertwisting hamiltonian. the squeezing parameters given by wineland et al and also by kitagawa et al. are chosen as the criteria of spin squeezing. the criterion of pairwise entanglement is chosen to be the concurrence and that of the bipartite entanglement the linear entropy. we also define...

We first of all propose a simple definition of a thermal squeezed state. Previous definitions of thermal coherent states and squeezed states[1, 2] have used the thermofield approach of Takahashi and Umezawa[3]. An early paper by Vourdas[4] discusses the superposition of squeezed states with thermal photons; a more recent paper[5] considers only the case of thermal coherent states. An early stud...

Surface-active properties of ubiquinones and ubiquinols have been investigated by monomolecular-film techniques. Stable monolayers are formed at an air/water interface by the fully oxidized and reduced forms of the coenzyme; collapse pressures and hence stability of the films tend to increase with decreasing length of the isoprenoid side chain and films of the reduced coenzymes are more stable ...

The insertion of immunoglobulin (IgG) in a glycolipid monolayer was achieved by using the ability of new proteo-glycolipid vesicles to disintegrate into a mixed IgG-glycolipid interfacial film after spreading at an air-buffer interface. The interfacial disintegration kinetics was shown to be directly dependent on the initial vesicle surface density and on the buffer ionic strength. The presence...

This paper gives a review of the phase and intensity quantum correlation between two photons in the process of optical parametric down-conversion (OPDC). Special emphasis is on the squeezed spectrum and squeezed intensity fluctuations in non-degenerate OPDC above threshold. Several experimental results of squeezed spectra and sub shot-noise intensity fluctuations are presented. PACS number(s): ...
