    Reconnections of wave vortex lines


    Berry, MV & Dennis, MR, 2012, ‘Reconnections of wave vortex lines’. European Journal of Physics, vol 33., pp. 723-731


    When wave vortices, that is nodal lines of a complex scalar wavefunction in space, approach transversely, their typical crossing and reconnection is a two-stage process incorporating two well-understood elementary events in which locally coplanar hyperbolas switch branches. The explicit description of this reconnection is a pedagogically useful illustration of several concepts: singularity, codimension, unfolding, genericity, bifurcation and normal forms.
