dot() [2/2]

Operator syten::MPS::dot	(	Operator const &	a,
		Operator const &	b,
		Sector const &	target
	)

Scalar product of two operators, i.e. the product of the operators projected on the supplied vacuum sector.

Parameters

a	first operator
b	second operator
target	target sector

Returns

\( \left( \hat b^\dagger \hat a\right)_{\mathrm{target}} \), i.e. a is first applied, then the dual space conjugate of b (not necessarily the same as the hermitian conjugate).
