this work reports on the magnetic reversal of sub-@xmath0 m sized elements consisting of an cofeb / ru / cofeb artificial ferrimagnet ( afi ) . the elements were patterned into ellipses having a width of approximately 250 to 270 nm and a varying aspect ratio between 1.3 and 8 . the coercivity was found to decrease with...

in quantum computation , quantum coherence must be maintained during gate operation . however , in physical implementations , various couplings with the environment are unavoidable and can lead to a dephasing of a quantum bit ( qubit ) . the background charge fluctuations are an important dephasing process , especially...

quantum correlations between two neighbor atoms are studied . it is assumed that one atomic system comprises a single auto - ionizing level and the other atom does not contain any auto - ionizing level . the excitation of both atoms is achieved by the interaction with the same mode of the quantized field . it is shown ...
