... that a photon polarized obliquely to the optic axis can be regarded as being partly in a state of polarization parallel to the axis, and partly in a state of polarization perpendicular to the axis ... linear momentum, an angular coordinate has an associated angular momentum, etc As is well-known, the behaviour of a classical system can be specified in terms of Lagrangian or Hamiltonian dynamics ... space FUNDAMENTAL CONCEPTS We say that |R is dependent on |A and |B It follows that the state R can be regarded as a linear superposition of the states A and B So, we can also say that state...
