Superconductors in a temperature gradient
Superconductor Science and Technology, 1995In the mixed state of a type II superconductor quasiparticles and magnetic flux quanta respond to a temperature gradient by thermal diffusion, in this way generating the Seebeck and Nernst effects, respectively. Our understanding of the Seebeck effect originates from an extension of the two-fluid counterflow concept, originally introduced by Ginzburg ...

Toroidal ion temperature gradient mode stability at large temperature gradients
Physica Scripta, 1997It is well known that the ion temperature gradient (ITG) or ηi mode (ηi = [(1/Ti)(dTi/dr)]/ [(1/n0)(dn0/dr)] = Ln/LT, Ln = density scale length, LT = temperature scale length) has an instability threshold (ηilow) around one for density scale lengths of the order of the magnetic field curvature radius LB.

On coronal temperatures, temperature gradients and compositions
Solar Physics, 1977Average solar wind properties at 1 AU either alone or together with the electron density distribution are used to obtain or review some results that relate coronal temperatures, temperature gradients, and compositions. Measured values of the temperature (T) and the temperature gradient parameter are used to find compositions that satisfy the equations ...

Metals in a Temperature Gradient
1990An electric current is a flow of charge; a heat current is a flow of thermal energy. An electron moving with velocity v contributes — ev to the electric current, and it contributes eTv to the heat current, where eT is the thermal energy of the electron. But what is the ‘thermal energy’ of an electron?

Diffusion in a Temperature Gradient
1983Diffusion in systems containing a mixture of chemical components is generally associated with a spatial non-uniformity of composition, but it can also arise from non-uniformity of other properties. The effect we are concerned with in these lectures is diffusion caused by a temperature gradient, which is known as thermotransport — the concept which was ...
