Approximation by point potentials in a magnetic field
We discuss magnetic Schrödinger operators perturbed by measures from the generalized Kato class. Using an explicit Krein-like formula for their resolvent, we prove that these operators can be approximated in the strong resolvent sense by magnetic Schrödinger operators with point potentials. Since the spectral problem of the latter operators is solvable, one in fact gets an alternative way to ca...
متن کاملTensor Product Spline Surface Approximation of a Discrete Point Field
1. Theoretical approach Designing the appropriate surface that approximates a certain point vector is one of the most challenging engineering tasks. Some of the aero and hydrodynamic profiles, materials plastic deformation technological problems are to be approached through surface approximation. Usually, the discrete input is achieved after coordinate measuring of a certain model. The designer...
متن کاملBlockade of sensory neuron action potentials by a static magnetic field in the 10 mT range.
To characterize the inhibitory effect of a static magnetic field, action potentials (AP) were elicited by intracellular application of 1 ms depolarizing current pulses of constant amplitude to the somata of adult mouse dorsal root ganglion neurons in monolayer dissociated cell culture. During the control period, < 5% of stimuli failed to elicit AP. During exposure to an approximately 11 mT stat...
متن کاملThe nematic critical point in the molecular field approximation
2014 The classical spin system with biquadratic exchange interaction and single spin anisotropy is analysed in the molecular field approximation. The temperature dependence of important thermodynamic quantities versus anisotropy strength is studied and the crossover from ordinary critical point behaviour to nematic point behaviour is discussed. The power-law parameters describing the temperatur...
متن کاملMagnetic field evolution in simulations with Euler potentials
Using twoand three-dimensional hydromagnetic simulations for a range of different flows, including laminar and turbulent ones, it is shown that solutions expressing the field in terms of Euler potentials (EP) are in general incorrect if the EP are evolved with an artificial diffusion term. In three dimensions, standard methods using the magnetic vector potential are found to permit dynamo actio...
