WebDensity matrix methods play an important role in the computation of spin dynamics. For systems that can be described by only one or two relevant spins, it is a straightforward, though tedious, exercise to work with the spin operators directly in an uncoupled basis. This is the approach taken by, e.g., Freed and co- WebThe quantum noise of the DQD F is neglected in what follows. The super-operator γ with matrix elements γ nm,n′m′ represents decoherence processes, including charge relaxation and dephasing due to charge noise (these processes also imply some degree of spin relaxation and dephasing due to spin-charge hybridization via B x M). church of christ southside https://oib-nc.net
