Member Enumeration Documentation

EnergyType

enum TBTK::ElectronFluctuationVertexCalculator::EnergyType

strong

Enum class for indicating whether the energy is an arbitrary comlex number, or if it is restricted to the real or imaginary axis.

Constructor & Destructor Documentation

ElectronFluctuationVertexCalculator()

TBTK::ElectronFluctuationVertexCalculator::ElectronFluctuationVertexCalculator

Destructor.

Member Function Documentation

calculateSelfEnergyVertex()

std::vector<std::complex<double> > TBTK::ElectronFluctuationVertexCalculator::calculateSelfEnergyVertex	(	const std::vector< double > &	k,
		const std::vector< int > &	orbitalIndices
	)

Calculate self-energy vertex.

createSlave()

ElectronFluctuationVertexCalculator* TBTK::ElectronFluctuationVertexCalculator::createSlave

(

)

Create slave ElectronFluctuationVertexCalculator. The slave reuses internal lookup tables used to speed up the calculations and should not be used after the generating master have been destructed.

generateInteractionAmplitudes()

void TBTK::ElectronFluctuationVertexCalculator::generateInteractionAmplitudes

(

)

Generate interaction amplitudes. Can be called multiple times and will only regenerate the interaction amplitudes when needed.

getEnergiesAreInversionSymmetric()

bool TBTK::ElectronFluctuationVertexCalculator::getEnergiesAreInversionSymmetric ( ) const

inline

Get wheter the energies are inversion symmetric.

getEnergyType()

ElectronFluctuationVertexCalculator::EnergyType TBTK::ElectronFluctuationVertexCalculator::getEnergyType ( ) const

inline

Get energy type.

getMomentumSpaceContext()

const RPA::MomentumSpaceContext & TBTK::ElectronFluctuationVertexCalculator::getMomentumSpaceContext ( ) const

inline

Get momentum cpsace context.

loadSusceptibilities()

void TBTK::ElectronFluctuationVertexCalculator::loadSusceptibilities ( const std::string &  filename )

inline

Load susceptibilities.

saveSusceptibilities()

void TBTK::ElectronFluctuationVertexCalculator::saveSusceptibilities ( const std::string &  filename ) const

inline

Save susceptibilities.

setEnergies()

void TBTK::ElectronFluctuationVertexCalculator::setEnergies ( const std::vector< std::complex< double >> &  energies )

inline

Set the energies for which the self-energy should be calculated.

setEnergiesAreInversionSymmetric()

void TBTK::ElectronFluctuationVertexCalculator::setEnergiesAreInversionSymmetric ( bool  energiesAreInversionSymmetric )

inline

Set to true if the energies can be assumed to be inversion symmetric in the complex plane.

Important note: Only set this to true if the energies passed to setEnergies() are on the form (-E_n, -E_{n-1}, ..., E_{n-1}, E_{n}. Setting this flag to true without fullfilling this condition will result in undefined behavior.

setEnergyType()

void TBTK::ElectronFluctuationVertexCalculator::setEnergyType ( EnergyType  energyType )

inline

Set self-energy energy type.

setJ()

void TBTK::ElectronFluctuationVertexCalculator::setJ ( std::complex< double >  J )

inline

Set J.

setJp()

void TBTK::ElectronFluctuationVertexCalculator::setJp ( std::complex< double >  Jp )

inline

Set Jp.

setU()

void TBTK::ElectronFluctuationVertexCalculator::setU ( std::complex< double >  U )

inline

Set U.

setUp()

void TBTK::ElectronFluctuationVertexCalculator::setUp ( std::complex< double >  Up )

inline

Set Up.
