متن کاملTMR Effect in a FM-QD-FM System
Using the Keldysh nonequilibrium technique, we study current and the tunnelling magnetoresistance (TMR) in a quantum dot coupled to two ferromagnetic leads (FM-dot-FM). The current is calculated for both parallel and antiparallel lead alignments. Coulomb interaction and spin-flip scattering are taken into account within the quantum dot. Interestingly, we find that these interactions play a cont...
متن کاملOn the recurrence fm+1=bmfm-fm-1 and applications
There's a proposition proclaimed to be new; it existed in eternity before us. The early authors are forgotten; and also the contemporary ones won't have any remembrance, though they are modern. Abstract We point out that a natural and direct way of analyzing the recurrence fm+1 = bmfm ?fm?1 is by means of continued fractions theory. Applications to exotic numeration systems and to games are giv...
متن کاملComparisons between PW Doppler system and enhanced FM Doppler system
This paper presents a new implementation of an formance, relative to the FM Doppler system reported echo-ranging FM Doppler system with improved perpreviously. The use of long sweeps provides a significant reduction in peak to average power ratio compared to pulsed wave (PW) emission. A PW Doppler system exploits the direct relationship between arrival time of the received signal and range from...
