netket.operator.SumOperator
netket.operator.SumOperator#
- class netket.operator.SumOperator#
Bases:
netket.operator.ContinuousOperatorThis class implements the action of the _expect_kernel()-method of ContinuousOperator for a sum of ContinuousOperator objects.
- Inheritance
- __init__(*operators, coefficients=1.0, dtype=None)[source]#
Returns the action of a sum of local operators. :type operators:
List:param operators: A list of ContinuousOperator objects :type coefficients:Union[float,List[float]] :param coefficients: A coefficient for each ContinuousOperator object :type dtype:Optional[Any] :param dtype: Data type of the matrix elements. Defaults to np.float64
- Attributes
- H#
Returns the Conjugate-Transposed operator
- Return type
- T#
Returns the transposed operator
- Return type
- hilbert#
The hilbert space associated to this operator.
- Return type
- is_hermitian#
- Methods
- collect()#
Returns a guaranteed concrete instance of an operator.
As some operations on operators return lazy wrappers (such as transpose, hermitian conjugate…), this is used to obtain a guaranteed non-lazy operator.
- Return type
- conj(*, concrete=False)#
- Return type
- conjugate(*, concrete=False)#
Returns the complex-conjugate of this operator.
- Parameters
concrete – if True returns a concrete operator and not a lazy wrapper
- Return type
- Returns
if concrete is not True, self or a lazy wrapper; the complex-conjugated operator otherwise
- transpose(*, concrete=False)#
Returns the transpose of this operator.
- Parameters
concrete – if True returns a concrete operator and not a lazy wrapper
- Return type
- Returns
if concrete is not True, self or a lazy wrapper; the transposed operator otherwise
