Magnetic field dependence of pairing interaction in ferromagnetic superconductors with triplet pairing
Magnetic field dependence of pairing interaction ferromagnetic superconductors triplet pairing

2010/11/23
It is developed a microscopic description of superconductivity in ferromagnetic materials with
triplet pairing triggered by the exchange of magnetic fluctuations. Instead widely used paramagnon model...
Direct observation of band-gap closure for a semiconducting carbon nanotube in a large parallel magnetic field

2010/11/23
We have investigated the magnetoconductance of semiconducting carbon nanotubes (CNTs) in
pulsed, parallel magnetic elds up to 60 T, and report the direct observation of the predicted band-gap closur...
Magnetic field correlations in a random flow with strong steady shear
Chaotic Dynamics (nlin.CD)

font style='font-size:12px;'>
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-...
Magnetic field induced reduction of the low-temperature superfluid density in cuprate superconductors
Magnetic field induced reduction cuprate superconductors

2010/11/18
The weak magnetic field induced reduction of the low-temperature superfluid density in cuprate
superconductors is studied based on the kinetic energy driven superconducting mechanism. The
electromag...
Thermodynamics of the HMF model with a magnetic field

font style='font-size:12px;'>
2010/11/19
We study the thermodynamics of the Hamiltonian Mean Field (HMF) model with an external
potential playing the role of a “magnetic field”. If we consider only fully stable states, this system does not ...

font style='font-size:12px;'>
2010/11/22
We study the effect of a weak magnetic field on the state of the spins of a pair of electrons forming a Cooper pair in an s-wave superconductor. By perturbatively solving time-dependent Bogoliubov equ...

font style='font-size:12px;'>
2010/11/19
In mesoscopic systems with spin-orbit coupling, spin-injection into quantum dots at zero magnetic eld is expected under a wide range of conditions. However, up to now, a viable approach for experimen...
