Charge dynamics and spin blockade in a hybrid double quantum dot
... explained as follows: (i) at ϵ ¼ 0, as the magnetic field is increased, the population of the singlet state decreases while the population of the T − triplet state increases (and eventually dominates for gμB B ≫ kB T), and (ii) the triplet state has a linear dependence on detuning and hence a zero q ...

... As an example, we return to the case of spin-1/2. With the notation previously established, we have Aη (F (x)) = Aη ( 12 (1 + 3b·x)) = T (b). But F (x) = 12 (1 + 3b · x) is not a fuzzy set function. In fact −1 ≤ F (x) ≤ 2. There are other forms of F that will also give T (b), but they are worse in t ...

Diverging equilibration times in long

Linear combinations of z components, however, commute with the Hamiltonian (2) and are therefore conserved quantities which do not equili ...
