The local stability of ion-temperature gradient driven mode (ITG) in the presence a given radial electric field is investigated using gyrokinetic theory and ballooning formalism with toroidal effect accounted for. It found that zero frequency field-induced poloidal rotation can significantly stabilize ITG, while associated density perturbation has little on ITG due to modification finite-orbit-...

The electric-field gradient (EFG) at nuclei in solids is a sensitive probe of the charge distribution. Experimental data, which previously only existed insulators, have been available for metals with development nuclear measuring techniques since about 1970. An early, systematic investigation temperature dependence EFG metals, originally based on results Cd, but then also extended to various ot...

An auxiliary poloidal inductive electric field applied to a reversed-field pinch (RFP) plasma reduces the current density gradient, slows the growth of m = 1 tearing fluctuations, suppresses their associated sawteeth, and doubles the energy confinement time. This experiment attacks the dominant RFP plasma loss mechanism of parallel streaming in a stochastic magnetic field. The auxiliary electri...

In many cases the electric field is the gradient of a potential. In those cases a measured voltage is completely determined by the points connected to the measuring device. But if the curl of the electric field vector is non-vanishing (i.e. the magnetic field is time-dependent), a measured voltage may depend on the topology of the circuit. This effect was discussed in articles by Romer (1982), ...

using hartree-fock su-sheriffer-heeger (hf-ssh) model, we have studied the dependence of the energies of the ground (magnetic triplet state) and the first exited (nonmagnetic singlet state) states of the size-2 trigonal zigzag graphene nanoflake (size-2 nf) on the intensity of an external in plane static electric field at zero temperature. we identify a transition from the magnetic triplet stat...

[1] Recent experimental and modeling studies show that large quasi-static electric fields (2–20 kV/m) can be developed in a Martian or terrestrial dust devil as a result of contact electrification and charge separation of dust grains with different sizes and compositions. Electric discharging occurs when the maximum electric field reaches breakdown values ( 20 kV/m on Mars and 3 MV/m on Earth, ...

this articles is comprised of two parts: a) an experimental investigation on the behavior of an acrylic gel under dc electric field and b) a physico - mathematical description.a) gel rods made of poly [acrylamide-co-bisacrylamide] were partially hydrolyzed to different extents at ph 12 by teteramethylethylene diamine. equlibrium properties of the resulting gels rods (water content, number of ca...

A dual dipole electric field probe has been used to measure surface electric fields in vivo on a human subject over a frequency range of 0.1-800 Hz. The low-frequency electric fields were induced by natural body movements such as walking and turning in the fringe magnetic fields of a 3 T magnetic resonance whole-body scanner. The rate-of-change of magnetic field (dB/dt) was also recorded simult...
