New linear stability parameter to describe low- electromagnetic microinstabilities driven by passing electrons in axisymmetric toroidal geometry
M. R. Hardman, F. I. Parra, B. S. Patel +8
In magnetic confinement fusion devices, the ratio of the plasma pressure to the magnetic field energy, , can become sufficiently large that electromagnetic microinstabilities b…

Stark shift control of single optical centers in diamond
Ph. Tamarat, T. Gaebel, J. R. Rabeau +8
Lifetime limited optical excitation lines of single nitrogen vacancy (NV) defect centers in diamond have been observed at liquid helium temperature. They display unprecedented spec…

Extended electron tails in electrostatic microinstabilities and the nonadiabatic response of passing electrons
M. R. Hardman, F. I. Parra, C. Chong +6
Ion-gyroradius-scale microinstabilities typically have a frequency comparable to the ion transit frequency. Due to the small electron-to-ion mass ratio and the large electron trans…
