This variable selects the method used to calculate the current density. For the moment this variable is for development purposes and users should not need to use it.
The calculation of current is done using the gradient operator. (Experimental)
The calculation of current is done using the gradient operator
with additional corrections for the total current from non-local operators.
The current density is obtained from the commutator of the
Hamiltonian with the position operator. (Experimental)
