Typedef Documentation

ComplexExpr

using Pomerol::LatticePresets::ComplexExpr = typedef Operators::expression<ComplexType, std::string, unsigned short, spin>

Complex-valued expression built out of lattice creation/annihilation operators. Each operator in the expression carries a site name label (a string index), an integer orbital index and a spin index.

Definition at line 50 of file LatticePresets.hpp.

RealExpr

using Pomerol::LatticePresets::RealExpr = typedef Operators::expression<RealType, std::string, unsigned short, spin>

Real-valued expression built out of lattice creation/annihilation operators. Each operator in the expression carries a site name label (a string index), an integer orbital index and a spin index.

Definition at line 46 of file LatticePresets.hpp.

Enumeration Type Documentation

spin

enum Pomerol::LatticePresets::spin : short

Possible values of spin-1/2 z-projection.

Enumerator
undef	Undefined (useful for bosonic degrees of freedom)
down	Spin down.
up	Spin up.

Definition at line 31 of file LatticePresets.hpp.

Function Documentation

operator<<()

std::ostream& Pomerol::LatticePresets::operator<<	(	std::ostream &	os,
		spin	s
	)

Output stream insertion operator for the spin projection values.

Parameters

[out]	os	Output stream.
[in]	s	Spin projection to be inserted.

Returns

Reference to the output stream.
