SectionHamiltonian Type integer Default gradient_corrected
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.
Options:
gradient:
The calculation of current is done using the gradient operator. (Experimental)
gradient_corrected:
The calculation of current is done using the gradient operator
with additional corrections for the total current from non-local operators.
hamiltonian:
The current density is obtained from the commutator of the
Hamiltonian with the position operator. (Experimental)
