ParticleNumber¶

class ParticleNumber(num_spatial_orbitals)[source]¶

The ParticleNumber property.

The following attributes can be set via the initializer but can also be read and updated once the ParticleNumber object has been constructed.

num_spatial_orbitals¶

the number of spatial orbitals.

Parameters:: num_spatial_orbitals (int) – the number of spatial orbitals in the system.

Methods

interpret(result)[source]¶

Interprets an EigenstateResult in this property’s context.

Parameters:: result (EigenstateResult) – the result to add meaning to.

second_q_ops()[source]¶

Returns the second quantized particle number operator.
