    "abstract": "Huygens\u0027 principle following from the d\u0027Alembert wave equation is not valid\nin two-dimensional space. A Schrodinger particle of vanishing angular momentum\nmoving freely in two dimensions experiences an attractive force - the quantum\nanti-centrifugal force - towards its center. We connect these two phenomena by\ncomparing and contrasting the radial propagators of the d\u0027Alembert wave\nequation and of a free non-relativistic quantum mechanical particle in two and\nthree dimensions.",
