Numerical generalised cumulant expansion route to the relaxation superoperator to second order, which is equivalent to Redfield theory.
Contents
Syntax
R=ngce(H,dt)
Arguments
H - a cell array of spin Hamiltonian commutation
superoperators obtained from an MD trajectory
dt - time step of the MD trajectory, seconds
Outputs
R - laboratory frame relaxation superoperator
Notes
The trajectory must be at least five times longer than the longest correlation time expected in the system.
