Revisiting Jahn--Teller Transitions in Correlated Oxides with Monte Carlo Modeling (opens in new tab)

arXiv:2601.09705v1 Announce Type: new Abstract: Jahn--Teller (JT) distortions are a key driver of physical properties in many correlated oxide materials. Cooperative JT distortions, in which long-range orbital order reduces the symmetry of the average structure macroscopically, are common in JT-distorted materials at low temperatures. This long-range order will often melt on heating, \textit{via} a transition to a high-temperature state without long-range orbital order. The nature of this tr...
