NumberPhase

NumberPhase(real angle, integer i) -> RealOperatorFermiParam

Returns the site number phase operator $\exp(i \phi n_i)$ with support on the specified site.

Parameters

• angle: The phase angle $\phi$ in radians.
• i: The site index where the operator acts.

Example

NumberPhase(pi,0)*Fbit("1000") // Returns (-1 + 0i)|1000>
