netket.operator.ContinuousOperator#

class netket.operator.ContinuousOperator#

Bases: netket.operator.AbstractOperator

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.

__init__(hilbert, dtype=<class 'float'>)[source]#

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 (Any) – Data type of the matrix elements. Defaults to np.float64

Attributes
H#

Returns the Conjugate-Transposed operator

Return type

AbstractOperator

T#

Returns the transposed operator

Return type

AbstractOperator

dtype#
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()#

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)#
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
