netket.operator.AbstractOperator

class netket.operator.AbstractOperator

Bases: 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

T

Returns the transposed operator

dtype

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

hilbert

The hilbert space associated to this operator.

is_hermitian

Returns true if this operator 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:

AbstractOperator

conj(*, concrete=False)

Return type:

AbstractOperator

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:

AbstractOperator

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:

AbstractOperator

Returns:

if concrete is not True, self or a lazy wrapper; the transposed operator otherwise
