Many-electron calculations of the phase stability of <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"><mml:msub><mml:mi>ZrO</mml:mi><mml:mn>2</mml:mn></mml:msub></mml:math> polymorphs

The authors show the shortcomings of density functional theory to produce a coherent description of theground state properties of ZrO${}_{2}$ polymorphs and show an alternative scheme using high-level many-electron methods.
