Mechanism of Magnetic Flux Loss in Molecular Clouds
, 2002 We investigate the detailed processes working in the drift of magnetic fields in molecular clouds. To the frictional force, whereby the magnetic force is transmitted to neutral molecules, ions contribute more than half only at cloud densities $n_{\rm H} <

Vibrationally Mediated Control of Single Electron Transmission in Weakly Coupled Molecule-Metal Junctions [PDF]
, 2010 We propose a mechanism which allows one to control the transmission of single electrons through a molecular junction. The principle utilizes the emergence of transmission sidebands when molecular vibrational modes are coupled to the electronic state ...
