Detailed Description

Container for instances of CreationOperator and AnnihilationOperator.

This container class stores instances of CreationOperator and AnnihilationOperator in associative maps with keys being their respective single-particle indices. It also provides methods that prepare and compute all stored MonomialOperator objects at once.

Constructor & Destructor Documentation

FieldOperatorContainer()

template<typename... IndexTypes>

Pomerol::FieldOperatorContainer::FieldOperatorContainer ( IndexClassification< IndexTypes... > const &  IndexInfo, HilbertSpace< IndexTypes... > const &  HS, StatesClassification const &  S, Hamiltonian const &  H, std::set< ParticleIndex >  in = {}  )

inline

Constructor.

Template Parameters

IndexTypes

Types of indices carried by the creation and annihilation operators.

Parameters

[in]	IndexInfo	Map for fermionic operator index tuples.
[in]	HS	Hilbert space.
[in]	S	Information about invariant subspaces of the Hamiltonian.
[in]	H	The Hamiltonian.
[in]	in	Set of all single-particle indices to store the MonomialOperator objects for. When empty, a set of all indices from IndexInfo is used.
