Detailed Description

Classification of many-body basis states into bases of invariant subspaces.

This class stores lists of Fock states belonging to each invariant subspace (block) of a Hilbert space.

Definition at line 43 of file StatesClassification.hpp.

Constructor & Destructor Documentation

StatesClassification()

Pomerol::StatesClassification::StatesClassification ( )

default

Construct without filling any Fock state lists.

Member Function Documentation

compute()

template<typename... IndexTypes>

void Pomerol::StatesClassification::compute ( HilbertSpace< IndexTypes... > const &  HS )

inline

Populate the Fock state lists from a HilbertSpace object. If the HilbertSpace is not in the ComputableObject::Computed state, then existence of just one invariant subspace coinciding with the full Hilbert space will be assumed.

Template Parameters

IndexTypes

Types of indices carried by operators acting in the Hilbert space HS.

Parameters

[in]

HS

The Hilbert space.
