Relaxation superoperator.
Contents
Syntax
R=relaxation(spin_system,euler_angles)
Arguments
euler_angles - (optional) spin system orientation, for
solid state systems at low temperature,
where the thermal equilibrium depends
on the orientation
Outputs
R - relaxation superoperator
Notes
- A variety of relaxation theories are supported, see the relaxation theory parameters section of the online manual.
- Spinach context functions include kinetics superoperators into the total Liovillian automatically.
- The function has been written for minimal memory footprint and performs aggressive memory recycling. Relaxation superoperator dimensions in excess of 1,000,000 are in practice feasible.
