Simulation worm algorithm 3 d optical lattice temperature system antiferromagnetic particles
2014/12/18
We perform a numeric study (Worm algorithm Monte Carlo simulations) of ultracold two-component bosons in two- and three-dimensional optical lattices. At strong enough interactions and low enough tempe...
Dynamical Ordering and Directional Locking For Particles Moving Over Quasicrystalline Substrates
Dynamical Ordering Directional Locking Quasicrystalline Substrates
2010/11/24
We use molecular dynamics simulations to study the driven phases of particles such as vortices
or colloids moving over a decagonal quasiperiodic substrate. In the regime where the pinned states have ...

2010/11/22
Neutron and x-ray diffraction studies of Ba(Fe1−xMnx)2As2 for low doping concentrations (x 6 0.176)reveal that at a critical concentration, 0.102 < x < 0.118, the tetragonal-to orthorhombic tran...
Commensurate antiferromagnetic ordering in Ba(Fe{1-x}Co{x})2As2 determined by x-ray resonant magnetic scattering at the Fe K-edge
Commensurate antiferromagnetic x-ray resonant magnetic Fe K-edge
2010/11/22
We describe x-ray resonant magnetic diffraction measurements at the FeK-edge of both the parent BaFe2As2 and superconducting Ba(Fe0.953Co0.047)2As2 compounds. From these high-resolution measurements w...
Effect of charge ordering on superconductivity in high-temperature superconductors
charge ordering high-temperature superconductors
2010/11/19
It is shown that charge ordering in layered crystalline metals causes an increase in the normal
state energy of the conducting layers. If this increase in the energy exceeds the difference between th...
Pressure-temperature phase diagram of charge ordering in Nd1/2Sr1/2MnO3
Pressure-temperature phase diagram Nd1/2Sr1/2MnO3
2010/11/17
We observe how the charge-ordering temperature TCO of Nd1/2Sr1/2MnO3 decreases with the external pressure p from 160 K at p = 0 down to 30 K at p ≃ 4.5 GPa, by measuring the
values p, T where t...

Magnetic properties of single crystalline EuPtGe3, crystallizing in the non-centrosymmetric BaNiSn3-type crystal strcuture have been studied by means of magnetisation, electrical resistivity, heat cap...
Rapidly fluctuating orbital occupancy above the orbital ordering transition in spin-gap compounds
Rapidly fluctuating orbital orbital ordering spin-gap compounds
2010/11/19
Several spin systems with low dimensionality develop a spin-dimer phase within a molecular orbital below TS, competing with long-range antiferromagnetic order. Very often, preferential orbital occupan...
Time Ordering Effects on Hydrogen Zeeman-Stark Line Profiles in Low-Density Magnetized Plasmas
Time Ordering Low-Density Magnetized Plasmas Hydrogen
2009/9/4
Stark broadening of hydrogen lines is investigated in low-density magnetized plasmas, at typical conditions of magnetic fusion experiments. The role of time ordering is assessed numerically, by using ...
