Relaxation properties in classical diamagnetism Relaxation properties in classical diamagnetism
It is an old result of Bohr that, according to classical statistical mechanics, at equilibrium a system of electrons in a static magnetic field presents no magnetization. Thus a magnetization can occur only in an out of equilibrium state, such as that produced through the Foucault currents when a magnetic field is switched on. It was suggested by Bohr that, after the establishment of such a non...
متن کاملModeling repulsive forces on fibres via knot energies
Modeling of repulsive forces is essential to the understanding of certain bio-physical processes, especially for the motion of DNA molecules. These kinds of phenomena seem to be driven by some sort of “energy” which especially prevents the molecules from strongly bending and forming self-intersections. Inspired by a physical toy model, numerous functionals have been defined during the past twen...
متن کاملDust in Magnetized Plasmas
Overview of recent progress in studies of magnetized dusty plasmas is presented. Dust dynamic under the influence of an applied magnetic field in various types of discharges and conditions (including dust dynamic in the magnetized plasma sheath) is examined. The various dust driven mechanisms in magnetized plasma are considered and comparison experimental and theoretical data is performed. Infl...
متن کاملMagnetic reconnection in weakly collisional highly magnetized electron-ion plasmas
A reduced three-field model of two-dimensional magnetic reconnection in a weakly collisional, highly magnetized plasma consisting of isothermal electrons and cold ions is derived from a set of Braginskii-like fluid equations. The model is then used to calculate the linear growth rate of the reconnecting instability in collisionless and semicollisional parameter regimes. © 2010 American Institut...
متن کاملOn global minimizers of repulsive–attractive power-law interaction energies
We consider the minimization of the repulsive-attractive power-law interaction energies that occur in many biological and physical situations. We show the existence of global minimizers in the discrete setting and obtain bounds for their supports independently of the number of Dirac deltas in a certain range of exponents. These global discrete minimizers correspond to the stable spatial profile...
