Time-domain spin dynamics under microwave irradiation.
Syntax
answer=dnp_time_dep(spin_system,parameters,H,R,K)
Parameters
parameters.mw_pwr - microwave power, rad/s
parameters.mw_off - microwave frequency offset
from free electron,rad/s
parameters.rho0 - thermal equilibrium state
parameters.coil - coil state vector or a hori-
zontal stack thereof
parameters.mw_oper - microwave irradiation operator
parameters.ez_oper - Lz operator on the electrons
parameters.dt - time step, seconds
parameters.nsteps - number of time steps
H - Hamiltonian commutation superoperator
R - thermalised relaxation superoperator
K - chemical kinetics superoperator
Outputs
answer - a matrix of projections of the trajectory on
each of the coils provided at each time step
Examples
Below is the output of examples/dnp_liquids/dnp_liquid_2.m example file.
Notes
The relaxation superoperator must be thermalised for this type of calculation.
