Observables
AtomicStructure.Observable
— TypeObservable
Represents a physical quantity that can be observed, which is calculated as the matrix element of an operator between two configurations. All physical observables are real.

AtomicStructure.observe!
— Functionobserve!(A::M, o::Observable)
Compute the observable o
between all configurations and store the results as matrix elements of A
.
observe!(A::M, atom::Atom, o::Observable)
Compute the observable o
between all configurations and store the results as matrix elements of A
. The right-hand side vectors are taken from the equations, whereas the lefth-hand side vectors are taken from atom
.
observe!(A::M, o::Observable, atom::Atom)
Compute the observable o
between all configurations, store the results as matrix elements of A
, and finally contract with respect to the mixing coefficients of atom
and return the result as a scalar. o
is not update!
d with respect to atom
.
observe!(A::M, o::Observable, a::Atom, b::Atom)
Compute the observable o
between all configurations, store the results as matrix elements of A
, and finally contract with respect to the mixing coefficients of atoms a
& b
and return the result as a scalar, which corresponds to a transition between the states of the respective atoms. o
will be update!
d with respect to b
.
