RIDME pulse sequence. Idealized hard pulses are used, the pulses only affect the user-specified electron.

Syntax

    answer=ridme(spin_system,parameters,H,R,K)

Arguments

  H                         Hamiltonian (received from the context
                            function)

  R                         relaxation superoperator (received from
                            the context function)

  K                         kinetics superoperator (received from
                            the context function)

  parameters.rho0           initial state

  parameters.probe_spin     number of the spin on which the
                            sequence operates

  parameters.stepsize       step size for the increment of 
                            the relaxation period, seconds

  parameters.nsteps(1)      number of steps for tau 1
 
  parameters.nsteps(2)      number of steps for tau 2

  parameters.tmix           mixing time, seconds

Outputs

  answer.pxpxpx.(real,imag)
  answer.pypypx.(real,imag)
  answer.mxmxpx.(real,imag)
  answer.mymypx.(real,imag) - quadrature components of the signal
                              corresponding to the phase cycle in-
                              stances on third, fourth, and fifth
                              pulse in the RIDME sequence

Examples

Am example of a RIDME simulation is available in examples/esr_solids/ridme_cu_nitroxide.m file.

Notes

For this experiment to work, relaxation must be present.
