Fundamentals of silicene
(2017-08-02)
Silicene is a single atomic layer of silicon (Si) much like graphene, the first example of an elemental twodimensional (2D) nanomaterial whose study led to the 2010 Nobel Prize in Physics. Until 2010 or so, the only known ...
Negative thermal expansion near two structural quantum phase transitions Connor
(2017-12-18)
Recent experimental work has revealed that the unusually strong, isotropic structural negative thermal
expansion in cubic perovskite ionic insulator ScF3 occurs in excited states above a ground state tuned very near a ...
Pressure dependence of ferroelectric quantum critical fluctuation
(2019-12-13)
Phase transitions to a long-range-ordered state driven by a softened phonon mode are ubiquitous across condensed matter physics, but the evolution of such a mode as the system is tuned to or from the transition has never ...
