Inertial and topological effects on a 2D electron gas

In this work, we study how the combination of rotation and a topological defect can influence the energy spectrumof a two dimensional electron gas in a strong perpendicularmagnetic field. A deviation from the linear behavior of the energy as a function ofmagnetic field, caused by a tripartite termof theHamiltonian, involvingmagneticfield, the topological charge of the defect and the rotation fr...

Influence of surface anisotropy on the hysteresis ofmagnetic nanoparticles

We present the results of Monte Carlo simulations of the magnetic properties of individual spherical nanoparticles with the aim to explain the role played by surface anisotropy on their low temperature magnetization processes. Phase diagrams for the equilibrium configurations have been obtained, showing a change from quasi-uniform magnetization state to a state with hedgehog-like structures at ...

An Analytic Study of the Reversal of Hartmann Flows by Rotating Magnetic Fields

The effects of a background uniform rotating magnetic field acting in a conducting fluid with a parallel flow are studied analytically. The stationary version with a transversal magnetic field is well known as generating Hartmann boundary layers. The Lorentz force includes now one term depending on the rotation speed and the distance to the boundary wall. As one intuitively expects, the rotatio...
