Detailed Description

Typedef Documentation

typedef struct MboElemOp_t* MboElemOp

Type for representing elementary operators.

MboElemOps are operators acting on an individual subsystem. Roughly speaking, MboElemOps correspond to single particle operators in a quantum mechanical context. Mathematically, MboElemOps are represented by an unordered collection of non-zero entries. MboElemOps can be used to created MboTensorOps (many-particle operators) by embedding them into a tensor product space.

Function Documentation

MBO_EXPORT MboElemOp mboAnnihilationOp ( MboLocInd dim )

Quantum mechanical harmonic oscillator annihilation operator.

The operator returned by this function must be freed with mboElemOpDestroy.

Parameters

dim	Dimension of space in which to build the annihilation operator.

Returns: The annihilation operator.

See also: mboElemOpDestroy, MboElemOp

MBO_EXPORT MboElemOp mboCreationOp ( MboLocInd dim )

Quantum mechanical harmonic oscillator creation operator.

The operator returned by this function must be freed with mboElemOpDestroy.

Parameters

dim	Dimension of space in which to build the creation operator.

Returns: The creation operator.

See also: mboElemOpDestroy, MboElemOp

MBO_EXPORT MBO_STATUS mboElemOpAddTo	(	MboLocInd	r,
		MboLocInd	c,
		struct MboAmplitude *	a,
		MboElemOp *	elemOp
	)

Add a non-zero entry to an MboElemOp.

Parameters

r	Row index of non-zero entry.
c	Column index of non-zero entry.
a	Matrix element of entry
elemOp	Elementary operator matrix to which to add the entry.

MBO_EXPORT int mboElemOpCheck ( MboElemOp elemOp )

Check internal integrity of an elementary operator.

Returns: Number of errors found.

MBO_EXPORT MboElemOp mboElemOpCopy ( MboElemOp elemOp )

copy an elementary operator

The copy returned by this function must be destroyed with mboElemOpDestroy.

Parameters

elemOp Operator to copy.

Returns: A copy of elemOp.

See also: mboElemOpDestroy, MboElemOp

MBO_EXPORT MBO_STATUS mboElemOpCreate ( MboElemOp * elemOp )

Create a MboElemOp object.

MboElemOps created with mboElemOpCreate have to be destroyed with mboElemOpDestroy.

See also: mboElemOpDestroy, MboElemOp

MBO_EXPORT void mboElemOpDeleteEntry	(	MboElemOp	elemOp,
		int	e
	)

Delete a non-zero entry from an operator.

Use mboElemOpNumEntries and mboElemOpGetEntries to determine e.

Parameters

elemOp	Operator from which to delete an entry.
e	The index of the entry to be delete.

See also: mboElemOpNumEntries, mboElemOpGetEntries, MboElemOp

MBO_EXPORT void mboElemOpDestroy ( MboElemOp * elemOp )

Destroy a MboElemOp object.

See also: mboElemOpCreate, MboElemOp

MBO_EXPORT struct MboNonZeroEntry* mboElemOpGetEntries ( MboElemOp elemOp )

Get the non-zero entries in the operator.

It is illegal to add entries or to delete entries or otherwise modify the pointer returned by mboElemOpGetEntries. Use mboElemOpDeleteEntry to delete an entry. Modifications to the entries in the array are allowed.

Parameters

elemOp Get the non-zero entries of this operator.
