In this work we show how new phase space methods lead to a more complete
visualisation of quantum states of atoms in ways that are not possible with
usual orbital methods. This method allows us to display quantum correlations
(entanglement) between spin and spatial degrees of freedom (spin-orbit
coupling), spin-spin degrees of freedom, and more complex combinations of spin
and spatial entanglement for the first time. This is important as such
properties affect the physical characteristics, and chemistry, of atoms and
molecules. Our visualisations are sufficiently accessible that, with some
preparation, those with a non-technical background can gain an appreciation of
subtle quantum properties of atomic and other systems. By providing new
insights and modelling capability, our phase space representation will be of
great utility in understanding aspects of atomic physics and chemistry not
available with current techniques.
