Fieldscan enlev.m

One-sentence summary of what the function does.

Syntax

    fieldscan_enlev(spin_system,parameters)

Description

Plots a user-specified number of the lowest energy levels of the system as a function of the applied magnetic field. The energies are obtained using the Arnoldi method.

Arguments

  parameters.fields  - two-element vector in Tesla,
                       ordered as [from to]

  parameters.npoints - number of points in the scan

  parameters.orientation - system orientation, three-
                           element vector containing
                           Euler angles in radians,
                           ordered as [alp bet gam]

  parameters.nstates - number of lowest energy states
                       to solve for

Outputs

This function plots a graph.

Examples

See quartet_levels.m, triple_dy_levels.m, and dy_lft_single_2.m files in examples/giant_spin directory.

Notes

The function runs in parallel over the values of the applied magnetic field. The sys.magnet parameter is used for internal normalisation and must be set to exactly 1 Tesla.
