Modeling contact formation between atomic-sized gold tips via molecular dynamics [PDF]

, 2015
The formation and rupture of atomic-sized contacts is modelled by means of molecular dynamics simulations. Such nano-contacts are realized in scanning tunnelling microscope and mechanically controlled break junction experiments.

Anisotropic excitonic effects in the energy loss function of hexagonal boron nitride [PDF]

, 2010
We demonstrate that the valence energy-loss function of hexagonal boron nitride (hBN) displays a strong anisotropy in shape, excitation energy and dispersion for momentum transfer q parallel or perpendicular to the hBN layers.

Micromagnetic analysis of geometrically controlled current-driven magnetization switching

AIP Advances, 2017
The magnetization dynamics induced by current pulses in a pair of two “S-shaped” ferromagnetic elements, each one consisting on two oppositely tilted tapered spikes at the ends of a straight section, is theoretically studied by means of micromagnetic ...

Quantum calculation of vortices in the inner crust of neutron stars [PDF]

, 2006
We study, within a quantum mechanical framework based on self-consistent mean field theory, the interaction between a vortex and a nucleus immersed in a sea of free neutrons, a scenario representative of the inner crust of neutron stars.

Study of the transition from pairing vibrational to pairing rotational regimes between magic numbers N=50 and N=82, with two-nucleon transfer

, 2011
Absolute values of two-particle transfer cross sections along the Sn-isotopic chain from closed shell to closed shell (100Sn,132Sn) are calculated taking properly into account nuclear correlations, as well as the successive, simultaneous and non ...

Spectral dependence of nonlinear absorption in ordered silver metallic nanoprism arrays

Scientific Reports, 2017
Ordered metallic nanoprism arrays have been proposed as novel and versatile systems for the observation of nonlinear effects such as nonlinear absorption.

A note on BPS vortex bound states

Physics Letters B, 2016
In this note we investigate bound states, where scalar and vector bosons are trapped by BPS vortices in the Abelian Higgs model with a critical ratio of the couplings.

Fluctuation-Induced Casimir Forces in Granular Fluids [PDF]

, 2006
We have numerically investigated the behavior of driven non-cohesive granular media and found that two fixed large intruder particles, immersed in a sea of small particles, experience, in addition to a short range depletion force, a long range repulsive ...

Scattering of light halo nuclei on heavy target at energies around the Coulomb barrier

EPJ Web of Conferences, 2014
We report here on experiments performed at TRIUMF to study the scattering of the light halo nuclei 11Li on lead at energies below and around the Coulomb barrier.
