Large isotropic negative thermal expansion above a structural quantum phase transition
Sahan U. Handunkanda, Erin B. Curry, Vladimir Voronov +5
Perovskite structured materials contain myriad tunable ordered phases of electronic and magnetic origin with proven technological importance and strong promise for a variety of ene…
Negative thermal expansion near two structural quantum phase transitions
Connor A. Occhialini, Sahan U. Handunkanda, Ayman Said +3
Recent experimental work has revealed that the unusually strong, isotropic structural negative thermal expansion in cubic perovskite ionic insulator ScF3 occurs in excited states a…
Cooperative elastic fluctuations provide tuning of the metal-insulator transition
G. G. Guzmán-Verri, R. T. Brierley, P. B. Littlewood
Metal to insulator transitions (MITs) driven by strong electronic correlations are common in condensed matter systems, and are associated with some of the most remarkable collectiv…
