TPPM DNP and its special case X-inverse-X (XiX) DNP experiment from (https://doi.org/10.1021/jacs.1c09900).
Syntax
contact_curve=xixdnp(spin_system,parameters,H,R,K)
Parameters
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
Outputs
contact_curve - time dependence of the coil state
Examples
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.
