Energetic-particle orbits near rational flux surfaces in stellarators: I. Passing particles
Thomas E. Foster, Felix I. Parra, Roscoe B. White +3
Recent simulations have shown that, even when the magnetic field of a stellarator possesses nested toroidal flux surfaces, the orbits of passing energetic particles can exhibit isl…
Damping of radial electric field fluctuations in the TJ-II stellarator
J L Velasco, J A Alonso, I Calvo +8
The drift kinetic equation is solved for low density TJ-II plasmas employing slowly varying, time-dependent profiles. This allows to simulate density ramp-up experiments and to des…
Vanishing neoclassical viscosity and physics of the shear layer in stellarators
J. L. Velasco, J. A. Alonso, I. Calvo +1
The drift kinetic equation is solved for low density TJ-II plasmas employing slowly varying, time-dependent profiles. This allows to simulate density ramp-up experiments and descri…
Zonal flows and long-distance correlations during the formation of the edge shear layer in the TJ-II stellarator
Ivan Calvo, Benjamin A. Carreras, Luis Garcia +2
A theoretical interpretation is given for the observed long-distance correlations in potential fluctuations in TJ-II. The value of the correlation increases above the critical poin…
Path integral formulation of fractional Brownian motion for general Hurst exponent
Ivan Calvo, Raul Sanchez
In J. Phys. A: Math. Gen. 28, 4305 (1995), K. L. Sebastian gave a path integral computation of the propagator of subdiffusive fractional Brownian motion (fBm), i.e. fBm with a Hurs…
Bopp operators and phase-space spin dynamics: Application to rotational quantum brownian motion
D. Zueco, Ivan Calvo
As already known for nonrelativistic spinless particles, Bopp operators give an elegant and simple way to compute the dynamics of quasiprobability distributions in the phase space…
