triqs::experimental::lattice::placeholders

Detailed Description

CLEF placeholders for the momentum and frequency arguments of integrable expressions.

These placeholders are the ones recognized by the Brillouin-zone integrators in this module: kx, ky and kz for the three momentum components and w for the frequency.

Variables
constexpr nda::clef::placeholder< 0 >	kx
	Placeholder for the first momentum component \( k_x \).
constexpr nda::clef::placeholder< 1 >	ky
	Placeholder for the second momentum component \( k_y \).
constexpr nda::clef::placeholder< 2 >	kz
	Placeholder for the third momentum component \( k_z \).
constexpr nda::clef::placeholder< 3 >	w
	Placeholder for the frequency \( \omega \).
