orientation.m

Anisotropic part of the Hamiltonian for a specific spin system orientation.

Syntax

    H=orientation(Q,euler_angles)

Arguments

  Q             -  rotational basis as returned by 
                   hamiltonian.m function

  euler_angles  -  a 1x3 vector specifying Euler 
                   angles (radians) relative to the
                   input orientation

Outputs

    H    -    anisotropic part of the Hamiltonian 
              for the specified Euler angles

Notes

This function may be used in both Hilbert and Liouville space because the H -> [H, ] adjoint map is linear.
