2014/12/20
Recent experiments in a mixture of two hyperfine states of trapped Bose gases show behavior analogous to a spin-1/2 system, including transverse spin waves and other familiar Leggett-Rice-type effects...

Interaction anisotropy and random impurities effects on the critical behaviour of ferromagnets
Interaction anisotropy random impurities effects critical behaviour of ferromagnets
2010/11/23
The theory of phase transitions is based on the consideration of "idealized" models, such as the Ising model: a system of magnetic moments living on a cubic lattice and having only two accessible stat...
Electron transport and anisotropy of the upper critical magnetic field in a Ba0.68K0.32Fe2As2 single crystals
Electron transport anisotropy of the upper critical magnetic field
2010/11/17
Early work on the iron-arsenide compounds supported the view, that a reduced dimensionality might be a necessary prerequisite for high–Tc superconductivity. Later, however, it was found that the zero-...

2010/11/25
We investigate the e ects of anisotropy on the stability and dynamics of vortex cluster states
which arise in Bose-Einstein condensates. Suciently strong anisotropies are shown to stabilize states w...
Symmetry breaking orbital anisotropy on detwinned Ba(Fe1-xCox)2As2 above the spin density wave transition
Symmetry breaking orbital anisotropy detwinned Ba
2010/11/17
Nematicity, defined as broken rotational symmetry, has recently been observed in the competing phases in proximity to the superconducting phase in the high TC cuprates (1-2). Similarly, the new iron-b...

2010/10/21
We demonstrate that the Casimir force between two dielectric slabs containing metallic wires will strongly depend on the relative orientation of the wires and can even change sign with rotation when a...
