Conductivity and the current–current correlation measure [PDF]
Journal of Physics A: Mathematical and Theoretical, 2010 We review various formulations of conductivity for one-particle Hamiltonians and relate them to the current-current correlation measure. We prove that the current-current correlation measure for random Schr dinger operators has a density at coincident energies provided the energy lies in a localization regime. The density vanishes at such energies and

Improved 3-Phase Current Transducer
Proceedings, 2018 We propose improved contactless DC/AC current transducer for 3-phase current lines based on 8 integrated fluxgate sensors. Using proper processing we ideally achieve a complete suppression of external homogeneous fields, and field gradients up to the 4th

Unknowns after the SNO Charged-Current Measurement [PDF]
, 2001 We perform a model-independent analysis of solar neutrino flux rates including the recent charged-current measurement at the Sudbury Neutrino Observatory (SNO). We derive a universal sum rule involving SNO and SuperKamiokande rates, and show that the SNO
