NumberPotential

Overloads

Name	Description
NumberPotential(const List<real> coefficients) -> FermionOperator	Returns an operator representing a weighted sum of number operators $\sum_{i=0}^{N-1} \alpha_i n_i$, where the site indices are implicitly $0, 1, \dots, N-1$. If a subset of sites or a different ordering is desired, use the factory overload that accepts an explicit list of site indices.
NumberPotential(const List<real> coefficients, const List<integer> sites) -> FermionOperator	Returns an operator representing a weighted sum of number operators $\sum_{i \in \mathrm{sites}} \alpha_i n_i$.

NumberPotential(const List<real> coefficients) -> FermionOperator

Returns an operator representing a weighted sum of number operators $\sum_{i=0}^{N-1} \alpha_i n_i$, where the site indices are implicitly $0, 1, \dots, N-1$. If a subset of sites or a different ordering is desired, use the factory overload that accepts an explicit list of site indices.

Parameters

• coefficients: The coefficients $\alpha_i$.

Example

var coefficients = [1.0,3.0,4.0,0.0]
NumberPotential(coefficients)*Fbit("0110") // Returns (7 + 0i)|0110>

NumberPotential(const List<real> coefficients, const List<integer> sites) -> FermionOperator

Returns an operator representing a weighted sum of number operators $\sum_{i \in \mathrm{sites}} \alpha_i n_i$.

Parameters

• coefficients: The coefficients $\alpha_i$.
• sites: The site indices where the operator acts.

Example

var sites = [0,2,3]
var coefficients = [1.0,3.0,4.0]
NumberPotential(coefficients,sites)*Fbit("0110") // Returns (3 + 0i)|0110>
