sp_acquire.m

Soft pulse followed by acquisition. The soft pulse is simulated using the Fokker-Planck formalism.

Syntax

    fid=sp_acquire(spin_system,parameters,H,R,K)

Parameters

    parameters.pulse_frq - frequency of the soft pulse,
                           relative to the frequency of
                           the current rotating frame, Hz

    parameters.pulse_phi - phase of the soft pulse, rad

    parameters.pulse_pwr - power of the soft pulse, rad/s

    parameters.pulse_dur - duration of the sof pulse, s

    parameters.pulse_rnk - Fokker-Planck cut-off rank,
                           a small integer: start with 2
                           and increase until the answer
                           stops changing

    parameters.offset    - transmitter / receiver offset
                           for the time domain pulses and
                           detection, relative to the cur-
                           rent rotating frame, Hz

    parameters.sweep     - sweep width for time domain
                           detection, Hz

    parameters.npoints   - number of points in the free
                           induction decay

    parameters.rho0      - initial state

    parameters.coil      - detection state

    parameters.method    - soft puse propagation method,
                           'expv' for Krylov propagation,
                           'expm' for exponential propa-
                           gation, 'evolution' for Spin-
                           ach evolution function

Outputs

    fid - dynamics of the coil state as a function of time
