Effect of asymmetric quantum dot rings in electron transport through a quantum wire
The electronic conductance at zero temperature through a quantum wire with side-connected asymmetric quantum ring (as a scatter system) is theoretically studied using the non-interacting Hamiltonian Anderson tunneling method. In this paper we concentrate on the configuration of the quantum dot rings. We show that the asymmetric structure of QD-scatter system strongly influences the amplitude an...

متن کاملBeam-cavity Interaction in Electron Storage Rings
A formal expression is obtained for the energy loss per . . _ turn, of a rigid bunch of electrons, to a closed cy lindrical cavity with quality factor Q. -The expression is valid provided the diameter of the entrance and exit ports for the beam are small ._.. .'compared to the bunch length. The effect of the ports is studied in an independent computational method. The energy loss is numerically...
متن کاملSpin Decoherence in Electron Storage Rings
A simple model of spin decoherence in electron storage rings is presented and its relevance to rf spin ipping at high energy is discussed.
متن کاملTrapped Macroparticles in Electron Storage Rings
Sudden drops of the beam lifetime ascribed to the capture of positively charged macroparticles (‘dust’) are observed at many high-energy electron storage rings. A trapped macroparticle has a certain thermal lifetime due to energy transfer from the beam; the interplay of different ionizing and discharging processes gives rise to an equilibrium charge. The beam lifetime is reduced by bremsstrahlu...
