TPPM DNP and its special case X-inverse-X (XiX) DNP experiment from (https://doi.org/10.1021/jacs.1c09900).




    H - Hamiltonian matrix, received from context function

    R - relaxation superoperator, received from context function

    K - kinetics superoperator, received from context function

    parameters.irr_powers - microwave amplitude (aka electron
                            nutation frequency), Hz 

    parameters.rho0       - initial state

    parameters.coil       - detection state

    parameters.pulse_dur  - pulse duration, seconds

    parameters.nloops     - number of XiX DNP blocks

    parameters.phase      - phase of the second pulse


    contact_curve         - time dependence of the coil state


The following XiX contact curve and field profile are produced by xix_contact_curve.m and xix_field_profile.m example file located in examples/dnp_solids directory of Spinach distribution.
