netket.operator.ContinuousOperator

class netket.operator.ContinuousOperator

Bases: AbstractOperator, Pytree

This class is the abstract base class for operators defined on a continuous Hilbert space. Users interested in implementing new quantum Operators for continuous Hilbert spaces should subclass ContinuousOperator and implement its interface.

Inheritance

__init__(hilbert, dtype=None)

Constructs the continuous operator acting on the given hilbert space and with a certain data type.

Parameters:

• hilbert (AbstractHilbert) – The underlying Hilbert space on which the operator is defined

• dtype (Union[None, str, type[Any], dtype, _SupportsDType]) – Data type of the operator, which is used to infer the dtype of expectation values

Attributes

H

Returns the Conjugate-Transposed operator

T

Returns the transposed operator

dtype

hilbert

The hilbert space associated to this observable.

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

replace(**kwargs)

Replace the values of the fields of the object with the values of the keyword arguments. If the object is a dataclass, dataclasses.replace will be used. Otherwise, a new object will be created with the same type as the original object.

Return type:

TypeVar(P, bound= Pytree)

Parameters:

• self (P)

• kwargs (Any)

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
