Ab initio simulations of iron–nickel alloys at Earth's core conditions
Abstract We report ab initio density functional theory calculations on iron–nickel (FeNi) alloys at conditions representative of the Earth's inner core. We test different concentrations of Ni, up to ∼39wt% using ab initio lattice dynamics, and...

Confinement and αs in a strong magnetic field
Abstract Hadron decay widths are shown to increase in strong magnetic fields as Γ ( eB ) ...

Forced deep-penetration welding with low-power second-harmonic assistance of cw copper welding with 1 μm wavelength
Abstract Laser welding of copper is a challenging process and therefore not yet well established in industrial applications. Due to the low absorptivity at wavelengths of 1 μm and above and the very high heat conductivity, the start of the process...

A worm algorithm for random spatial permutations
Abstract Models of random spatial permutations arise in the study of Bose-Einstein condensation. Namely, permutations of sites occur with probabilities depending on lengths of permutation jumps, as well as on interactions between jumps. Below a...

Oscillatory quantum interference effects in narrow-gap semiconductor heterostructures
Abstract We investigate quantum interference phenomena in narrow bandgap semiconductors under strong spin-orbit interaction, by measuring the magnetoresistance across mesoscopic closed-path structures fabricated in two-dimensional electron systems....

Tightly bound 3D quantum dot energy states in a magnetic field
Abstract We have analyzed the detailed quantum dynamics of a 3D quantum dot in a magnetic field. The dot is taken to be lodged in a bulk medium in a high magnetic field and it is represented by a three-dimensional Dirac delta function potential...

Electron Transfer in Ferritin as Probed by Muon Spin Relaxation
Abstract Electron-transfer processes play a vital role in many biological phenomena, from energy storage to photosynthesis. Positive muons allow such transfer processes in macromolecules, such as proteins, to be probed on a microscopic level. We...

Monte Carlo Simulation of Absorbing Phase Transition in the Models with a Conserved Field on Diluted Lattices
Abstract An influence of quenched disorder on absorbing phase transitions of the conserved lattice gas (CLG) model and the conserved threshold transfer process (CTTP) was investigated via Monte Carlo simulations. It was found that when the...

Photoacoustic transients generated by laser irradiation of thin films
Abstract Irradiation of an optically thin layer immersed in a transparent fluid with pulsed laser radiation can generate photoacoustic waves through two mechanisms. The first of these is the conventional optical heating of the layer followed by...

Nucleon spin structure at very high x
Abstract Dyson–Schwinger equation treatments of the strong interaction show that the presence and importance of nonpointlike diquark correlations within the nucleon are a natural consequence of dynamical chiral symmetry breaking. Using this...

Group theory and unification of forces: Application to ‘non-universal’ gaugino masses
Abstract We will give an overview on how to embed the Standard Model (SM), based on SU(3)× SU(2)× U(1), within larger groups. We will review the different chains one follows when spontaneously breaking...

Behaviour of the extended Volterra lattice
Abstract We investigate the behaviour of solutions of the recently proposed extended Volterra lattice. A variety of methods are used to determine the effects of the new terms on small amplitude equations, and, following approximation of the partial...

Measurement of the high-mass Drell–Yan differential cross-section in pp collisions at with the ATLAS detector
Abstract This Letter reports a measurement of the high-mass Drell–Yan differential cross-section in proton–proton collisions at a centre-of-mass energy of 7 TeV at the LHC. Based on an integrated luminosity of 4.9 ...

Boundary conditions and the generalized metric formulation of the double sigma model
Abstract Double sigma model with strong constraints is equivalent to the ordinary sigma model by imposing a self-duality relation. The gauge symmetries are the diffeomorphism and one-form gauge transformation with the strong constraints. We consider ...
