Charge Deficiency, Charge Transport and Comparison of Dimensions
We study the relative index of two orthogonal infinite dimensional projections which, in the finite dimensional case, is the difference in their dimensions. We relate the relative index to the Fredholm index of appropriate operators, discuss its basic properties, and obtain various formulas for it. We apply the relative index to counting the change in the number of electrons below the Fermi ene...
متن کاملCharge transfer and charge transport on the double helix
We present a short review of various experiments that measure charge transfer and charge transport in DNA. Some general comments are made on the possible connection between various ‘chemistry-style’ charge transfer experiments that probe fluorescence quenching and remote oxidative damage and ‘phys-style’ measurements that measure transport properties as defined typically in the solid-state. We ...
متن کاملMagnetic Charge Transport
It has recently been predicted that certain magnetic materials contain mobile magnetic charges or ‘monopoles’. Here we address the question of whether these magnetic charges and their associated currents (‘magnetricity’) can be directly measured in experiment, without recourse to any material-specific theory. By mapping the problem onto Onsager’s theory of weak electrolytes, we show that this i...
متن کاملDistant charge transport.
H ighlighting this issue of PNAS is a special feature comprising a Perspective and five research articles on the theme of long-range electron transfer. Distant electron transfers play key roles in aerobic respiration and photosynthe-sis, which work in concert: The oxygen that is evolved by photosynthetic organisms is the oxidant that sustains life in aerobic microbes and animals; and, in turn, ...
متن کاملFractional lattice charge transport
We consider the dynamics of noninteracting quantum particles on a square lattice in the presence of a magnetic flux α and a dc electric field E oriented along the lattice diagonal. In general, the adiabatic dynamics will be characterized by Bloch oscillations in the electrical field direction and dispersive ballistic transport in the perpendicular direction. For rational values of α and a corre...
