netket.operator.AbstractOperator¶

class netket.operator.AbstractOperator(hilbert)¶

Bases: abc.ABC

Abstract class for quantum Operators. This class prototypes the methods needed by a class satisfying the Operator concept.

Inheritance

Attributes

H¶

Returns the Conjugate-Transposed operator

Return type: AbstractOperator

T¶

Returns the transposed operator

Return type: AbstractOperator

dtype¶

The dtype of the operator’s matrix elements ⟨σ|Ô|σ’⟩.

Return type: Any

hilbert¶

The hilbert space associated to this operator.

Return type: AbstractHilbert

is_hermitian¶

Returns true if this operator is hermitian.

Return type: bool

size¶

The total number number of local degrees of freedom.

Return type: int

Methods

collect()[source]¶

Returns a guranteed concrete instancce of an operator.

As some operations on operators return lazy wrapperes (such as transpose, hermitian conjugate…), this is used to obtain a guaranteed non-lazy operator.

Return type: AbstractOperator

conj(*, concrete=False)[source]¶

Return type: AbstractOperator

conjugate(*, concrete=False)[source]¶

Returns the complex-conjugate of this operator.

Parameters: concrete – if True returns a concrete operator and not a lazy wrapper
Return type: AbstractOperator
Returns: if concrete is not True, self or a lazy wrapper; the complex-conjugated operator otherwise

transpose(*, concrete=False)[source]¶

Returns the transpose of this operator.

Parameters: concrete – if True returns a concrete operator and not a lazy wrapper
Return type: AbstractOperator
Returns: if concrete is not True, self or a lazy wrapper; the transposed operator otherwise
