RotY

RotY(real phi, integer site) -> OperatorParam<real>​

Returns a spin-1/2 RotY(ϕ)=exp⁡(−iϕY/2)(\phi) = \exp(-i\phi Y/2) rotation operator around the Y-axis.

Parameters​

  • phi: The rotation angle.
  • site: The site index where the operator acts.

Example​

var ry_quarter = RotY(0.7854, 1)  // π/4 rotation on site 1
