netket.operator._sum.SumGenericOperator

class netket.operator._sum.SumGenericOperator

Bases: SumOperator, AbstractOperator

Inheritance

Attributes

H

Returns the Conjugate-Transposed operator

T

Returns the transposed operator

coefficients

The coefficients for each operator term in the sum.

Each coefficient corresponds to \(c_i\) in the sum \(\sum_i c_i \hat{O}_i\), where each coefficient multiplies its corresponding operator from operators.

Returns:

A JAX array containing the scalar coefficients for each operator.

dtype

The data type of the operator coefficients.

Returns:

The numpy/JAX dtype used for the coefficients array.

hilbert

The hilbert space associated to this observable.

is_hermitian

operators

The tuple of all operators in the terms of this sum.

Each operator corresponds to a term \(\hat{O}_i\) in the sum \(\sum_i c_i \hat{O}_i\), where each operator is multiplied by its corresponding coefficient from coefficients.

Returns:

A tuple containing all the quantum operators being summed.

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
