We have carried out 1.25 pc resolution MHD simulations of the ISM, on a Cartesian grid of 0 ≤ (x, y) ≤ 1 kpc size in the galactic plane and −10 ≤ z ≤ 10 kpc into the halo, thus being able to fully trace the time-dependent evolution of the galactic fountain. The simulations show that large scale gas streams emerge, driven by SN explosions, which are responsible for the formation and destruction ...

A new method for the solution of the two electron problem in a strong magnetic eld is presented that combines the well known hyperspherical close coupling and nite element methods and applied to helium in a magnetic eld of up to 10 5 Tesla, giving energy levels of low-lying S{ and P { states up 1 to a principal quantum number of n = 4 as well as wavelengths of selected transitions.

We display the eeects of the magnetic eld on the light yield of the tiles used in the Atlas Hadronic Calorimeter. Covering a large range, from the Earth eld to about 1 Tesla, these results are in agreement with other experiments showing that the light yield of polystyrene based scintillator is increased by about 1% below about 100 mT, with a jump of about 0.6% at 1.2 mT and a 1% plateau startin...

The distribution of magnetic eld magnitudes is derived for the special case of a constant mean eld and uncorrelated components having Gaussian distributions. Of the three cases considered{ isotropic, transverse, and axisymmetric, the latter most closely resembles a lognormal distribution, when the parallel variance is less than the perpendicular variance. Thus, a normally distributed, non-inter...

We discuss the occurrence of Bose-Einstein condensation in systems of noninteracting charged particles in three and one dimensions and in presence of an external magnetic eld. In the one dimensional, as well as in the magnetic eld cases, although not a critical temperature, a characteristic temperature can be found, corresponding to the case in which the ground state density becomes a macroscop...

We study the Ginzburg-Landau energy of superconductors submitted to a possibly non-uniform magnetic eld, in the limit of a large Ginzburg-Landau parameter. We prove that the induced magnetic elds associated to minimizers of the energy-functional converge as ! +1 to the solution of a free-boundary problem. This free boundary-problem has a nontrivial solution only when the applied magnetic eld is...

The factors that make certain magnetic materials behave similarly to corresponding Ising models are reviewed. Examples of extensively studied materials include Dy(C2H5SO4)3.9H2) (DyES), Dy3Al5O12 (DyAlG), DyPO4, Dy2Ti2O7, LiTbF4, K2CoF4, and Rb2CoF4. Various comparisons between theory and experiment for these materials are examined. The agreement is found to be generally very good, even when th...

Magnetic torquing is attractive for generation of control torques on small satellites. The concept is that interaction between the Earth's magnetic eld and a magnetic eld generated by a set of coils in the satellite is used for actuation. This principle is inherently nonlinear, and diicult to use because control torques can only be generated perpendicular to the geomagnetic eld vector. So far, ...
