The required bias field of a sperimagnetic film is governed by a finite exchange coupling coefficient ~l! mainly determined by the subnetwork coupling. From the study of a series of ~Dy,Tb!FeCo films ...
Exchange coupling coefficient and domain wall mobility of (Dy,Tb)FeCo magneto-optical films
2011/11/30
The magnetic properties and recording characteristics of ~Dy,Tb!FeCo films are dependent upon the anisotropy dispersion of rare earth constituents and the exchange integral between rare earth and tran...
Application and Analysis of Archetype Coupling in Urban Design — Taking the Special Planning for the Space Layout of Xishui City, Guizhou Province for Example
Archetype Archetype Coupling Charm Network Spatial Archetype Urban Design Urban Features

Bottle microresonator evanescent coupling sub-wavelength-diameter coupling fiber
2011/8/11
Abstract: The evanescent coupling of light between a whispering-gallery-mode bottle microresonator and a sub-wavelength-diameter coupling fiber is actively stabilized by means of a Pound-Drever-Hall t...
Threshold Improvement of Low-Density Lattice Codes via Spatial Coupling
Low-Density Lattice Codes Spatial Coupling Information Theory
2011/9/20
Abstract: Spatially-coupled low-density lattice codes (LDLC) are constructed using protographs. Using Monte Carlo density evolution using single-Gaussian messages, we observe that the threshold of the...
Optimized coupling of cold atoms into a fiber using a blue-detuned hollow-beam funnel
Optimized coupling cold atoms fiber blue-detuned hollow-beam funnel
2011/8/11
Abstract: We theoretically investigate the process of coupling cold atoms into the core of a hollow-core photonic-crystal optical fiber using a blue-detuned Laguerre-Gaussian beam. In contrast to the ...
We determine the value of the omega -rho- pi mesons coupling (g_{omega rho pi}), in the context of the vector meson dominance model, from radiative decays, the omega -> 3 pi decay width and the e^+e^-...
Thomas-Fermi approximation to pairing in finite Fermi systems. The weak coupling regime
Thomas-Fermi approximation to pairing Fermi systems weak coupling regime
2011/7/20
We present a new semiclassical theory for describing pairing in finite Fermi systems. It is based on taking the $\hbar \to 0$, i.e. Thomas-Fermi, limit of the gap equation written in the basis of the ...
A simple linear response closure approximation for slow dynamics of a multiscale system with linear coupling
closure approximation slow dynamics multiscale system linear coupling
2011/9/14
Abstract: Many applications of contemporary science involve multiscale dynamics, which are typically characterized by the time and space scale separation of patterns of motion, with fewer slowly evolv...

Abstract: Using SU(2)X SU(2) Lie-group structure we obtain the algebraization of 2D harmonic oscillator model with complex quadratic coupling. It is shown that the original time-independent Schr\"odin...
Cluster Synchrony in Systems of Coupled Phase Oscillators with Higher-Order Coupling
Cluster Synchrony Coupled Phase Oscillators Higher-Order Coupling

Abstract: We study the phenomenon of cluster synchrony that occurs in ensembles of coupled phase oscillators when higher-order modes dominate the coupling between oscillators. For the first time, we d...
Varying disc-magnetosphere coupling as the origin of pulse profile variability in SAX J1808.4-3658
accretion accretion discs – pulsars:individual:SAX J1808.4–3658 – stars:neu-tron – X-rays:binaries
2011/9/26
Accreting millisecond pulsars show significant variability of their pulse profiles, especially at low accretion rates. On the other hand, their X-ray spectra are remarkably similar with not much varia...
