Constructor & Destructor Documentation

InteractionAmplitude() [1/4]

TBTK::InteractionAmplitude::InteractionAmplitude

(

)

Constructor.

InteractionAmplitude() [2/4]

TBTK::InteractionAmplitude::InteractionAmplitude	(	std::complex< double >	amplitude,
		std::initializer_list< Index >	creationOperatorIndices,
		std::initializer_list< Index >	annihilationOperatorIndices
	)

Constructor.

InteractionAmplitude() [3/4]

TBTK::InteractionAmplitude::InteractionAmplitude	(	std::complex< double >(*)(const std::vector< Index > &, const std::vector< Index > &)	amplitudeCallback,
		std::initializer_list< Index >	toIndex,
		std::initializer_list< Index >	fromIndex
	)

Constructor. Takes a callback function rather than a parameter value. The callback function has to be defined such that it returns a value for the given indices when called at run time.

InteractionAmplitude() [4/4]

TBTK::InteractionAmplitude::InteractionAmplitude

(

const InteractionAmplitude &

ia

)

Copy constructor.

~InteractionAmplitude()

TBTK::InteractionAmplitude::~InteractionAmplitude

(

)

Destructor.

Member Function Documentation

getAmplitude()

std::complex< double > TBTK::InteractionAmplitude::getAmplitude ( ) const

inline

Get the amplitude value \(a_{\{c\}\{a\})}\), where \(\{c\}\) and \(\{a\}\) are sets of creation and annihilation operator indices.

getAnnihilationOperatorIndex()

const Index & TBTK::InteractionAmplitude::getAnnihilationOperatorIndex ( unsigned int  n ) const

inline

Get annihilation operator index.

getCreationOperatorIndex()

const Index & TBTK::InteractionAmplitude::getCreationOperatorIndex ( unsigned int  n ) const

inline

Get creation operator index.

getNumAnnihilationOperators()

unsigned int TBTK::InteractionAmplitude::getNumAnnihilationOperators ( ) const

inline

Returns the number of annihilation operator indices.

getNumCreationOperators()

unsigned int TBTK::InteractionAmplitude::getNumCreationOperators ( ) const

inline

Returns the number of creation operator indices.
