Augmented quasiparticle (QP) mappings, as applied to indistinguishable point sets of (Liouvillian) democratic-recoupled (DR) tensors, provide for a 1:1 invariant labelling of the underlying (disjoint) dual projective map carrier subspaces, where the Liouville pattern basis set is defined via superboson unit-tensor actions on a null space, |∅〉〉. The(More)
The powder lineshapes, associated with Zeeman-NQR A\m\= + 1 transitions for half-integer spin from 3/2 and 7/2 are derived using an optimized (6, (j)) sampling algorithm for the intensity response. The 1 = 3/2 system is examined over the full asymmetry range, whereas the I >3/2 lineshapes are calculated for r j^0.35. The algorithm adopted is modelled on the(More)
The structure o f the anisotropic indirect quadrupolar spin-spin interaction, and its effect on the spin dynamics associated with pure N Q R time-domain response, is considered in terms of spherical tensor operator bases and multipole theory. The advantages o f symmetry-adapting the Liouville bases is discussed for I S 3/2 spin systems. In particular,(More)
The physics of dual group scalar invariants (SIs) as (Lie algebraic) group measures (L-GMs) and its significance to non-Abelian NMR spin systems motivates this overview of uniform general-2n [AX](2n) spin evolution, which represents an extensive addendum to Corio's earlier (essentially restricted) view of Abelian spin system SU(2)-based SI-cardinalities.(More)
