netket.operator.KineticEnergy#
- class netket.operator.KineticEnergy[source]#
Bases:
ContinuousOperatorThis is the kinetic energy operator (hbar = 1). The local value is given by: \(E_{kin} = -1/2 ( \sum_i \frac{1}{m_i} (\log(\psi))'^2 + (\log(\psi))'' )\)
- Inheritance
- __init__(hilbert, mass, dtype=None)[source]#
Args: hilbert: The underlying Hilbert space on which the operator is defined mass: float if all masses are the same, list indicating the mass of each particle otherwise dtype: Data type of the mass
- Parameters:
hilbert (AbstractHilbert)
dtype (Any | None)
- Attributes
- H#
Returns the Conjugate-Transposed operator
- T#
Returns the transposed operator
- dtype#
- hilbert#
The hilbert space associated to this observable.

- mass#
- 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:
- conj(*, concrete=False)#
- Return type:
- 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:
- 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:
- Returns:
if concrete is not True, self or a lazy wrapper; the transposed operator otherwise
