Noise-induced forced synchronization of global variables in coupled bistable systems
(IOP Publishing Ltd., 2007-09)
We analyze the noise-induced synchronization between a collective variable characterizing a complex system with a finite number of interacting bistable units and time-periodic driving forces. A random phase process associated ...

Wetting transition of a nematic liquid crystal on a periodic wedge-structured substrate
(EDP Sciences, 2007)
It is known that the wetting behaviour of a fluid is deeply altered by the presence of rough or structured substrates. We first review some simple considerations about isotropic fluids and rough substrates, and then we ...

Use of Parsons-Lee and Onsager theories to predict nematic and demixing behavior in binary mixtures of hard rods and hard spheres
(American Physical Society, 2007)
Parsons-Lee and Onsager theories are formulated for the isotropic-nematic transition in a binary mixture of hard rods and hard spheres. Results for the phase coexistence and for the equation of state in both phases ...

Three-body description of direct nuclear reactions: Comparison with the continuum discretized coupled channels method
(American Physical Society, 2007)
The continuum discretized coupled channels (CDCC) method is compared with the exact solution of the three-body Faddeev equations in momentum space. We present results for (i) elastic and breakup observables of d + 12 C ...

Nuclear polarizability of helium isotopes in atomic transitions
(American Physical Society, 2007-03-28)
We estimate the nuclear polarizability correction to atomic transition frequencies in various helium isotopes. This effect is non-negligible for high precision tests of quantum electrodynamics or accurate determination of ...

Approximate Lane consistency of the dispersive coupled-channels potential for actinides
(The American Physical Society, 2007)
A previously derived dispersive coupled-channels optical model potential for nucleon scattering on 232Th and 238U nuclei [Capote, Soukhovitskii, Quesade, and Chiba, Phys. Rev. C 72, 064610 (2005)] has been tested against ...

Forced synchronization of a quantum dissipative dynamics
(American Institute of Physics, 2007)
We generalize the phenomenon of forced stochastic synchronization into the quantum domain within the framework of a paradigmatic spin-boson model (tunneling charge, or flipping spin 1/2 coupled to an environment) which ...

Measurement of the radiative neutron capture cross section of 206 Pb and its astrophysical implications
(The American Physical Society, 2007)
The (n,γ) cross section of 206Pb has been measured at the CERN n_TOF facility with high resolution in the energy range from 1 eV to 620 keV by using two optimized 6C6D detectors. In the investigated energy interval about ...

Controlling the order of wedge filling transitions: the role of line tension
(2007)
We study filling phenomena in 3D wedge geometries paying particular attention to the role played by a line tension associated with the wedge bottom. Our study is based on transfer matrix analysis of an effective one dimensional ...

Superscaling and neutral current quasielastic neutrino-nucleus scattering beyond the relativistic Fermi gas model
(The American Physical Society, 2007)
The superscaling analysis is extended to include quasielastic (QE) scattering via the weak neutral current (NC) of neutrinos and antineutrinos from nuclei. The scaling function obtained within the coherent density fluctuation ...
