TL;DR: An isostructural, purely electronically driven metal-insulator transition is demonstrated in epitaxial heterostructures of an archetypal correlated material, vanadium dioxide, to provide insights into phase transitions of correlated materials and may aid the design of device functionalities.

TL;DR: In this paper, the authors used stroboscopic electron diffraction to find an electrically triggered, isostructural state that forms transiently on microsecond time scales, which is stabilized by local heterogeneities and interfacial interactions between the equilibrium phases.

TL;DR: In this article, the distortion symmetry method is used to discover hidden pathways for the case studies of bulk ferroelectric switching and domain wall motion in proper and improper ferroelectrics, as well as in multiferroic switching.

TL;DR: In this paper, the authors combine the Landau theory description of thermodynamics and the phase-field method to investigate and understand the formation of the incommensurate phase in hexagonal manganites.

TL;DR: In this paper, a phenomenological Ginzburg-Landau potential incorporating both a structural order parameter and a spin-correlation order parameter was proposed to explicitly capture the structural distortion and the electronic phase transition in VO2.
