Bohmian circulation of an angular-momentum eigenstate
= Bohmian circulation of an angular-momentum eigenstate

{title2=$v_\phi=\hbar k/(mr)$}
For the <separation of a two-dimensional central-potential eigenstate>, the <guidance equation> gives zero radial velocity and constant-radius circular motion, with circulation $2\pi\hbar k/m$. A real superposition of the degenerate $k$ and $-k$ <eigenstates> has zero current away from nodes instead. The speed depends on the actual <wavefunction>, not just its energy.
