This talk will explore some of the unusual phase behaviour of framework materials – including hybrid perovskite analogues – driven by ordering of molecular degrees of freedom. Two specific examples to be covered are an incommensurate chirality density wave state and a structural analogue of Lieb’s square ice phase. The relevance of direction-dependent interaction models (including a classical Kitaev-like formalism) to the structural complexity of framework materials will be discussed in general terms, before exploring the connection between strongly-correlated structural disorder in these systems and various cooperative phenomena. The talk will conclude with a study of Prussian Blue analogues, where strong geometric frustration leads to an unexpectedly complex phase behaviour characterised by “hidden” polymorphism.

This talk is part of the Theory of Condensed Matter series.
