Diamond siv0.m

SiV0 spin system for diamond. Magnetic parameters from Edmonds et al., Phys. Rev. B 77, 245205 (2008), DOI link. The spin system contains one spin-1 electron, optionally a silicon nucleus, and up to six 13C nuclei. The g-tensor, with principal values [2.0035 2.0035 2.0042], and the axial zero-field splitting with D=1000 MHz are built in the trigonal [111] principal axis frame. When '29Si' is requested, a silicon nucleus with an axial hyperfine tensor of [78.9 78.9 76.3] MHz is added; when a silicon isotope other than '29Si' or 'none' is requested, the nucleus is added without a hyperfine tensor. Each of the requested nearest-neighbour carbons receives the same axial hyperfine tensor with principal values [30.2 30.2 66.2] MHz. All tensors are then rotated by the matrix that aligns the requested crystal plane normal with the magnetic field direction; the zero-field splitting is converted into irreducible spherical form by mat2ias.m, and the result is returned in the zeeman.matrix and coupling.matrix fields.

Syntax

    [sys,inter]=diamond_siv0(parameters)

Parameters

    parameters is a structure with the following required fields:

      .silicon      - '29Si', 'none', or another silicon isotope
      .orientation  - '111', '110', or '100' crystal plane normal
                      aligned with the magnetic field
      .n_13c       - number of reported nearest-neighbour 13C
                     hyperfine couplings, between 0 and 6

Outputs

    sys   - Spinach system specification structure

    inter - Spinach interaction specification structure

Notes

All three of .silicon, .orientation and .n_13c are required; .n_13c must be an integer between 0 and 6.
