Ca2RuO4 exemplifies the rich interplay between strong electron correlations and lattice dynamics that characterise Mott insulators. In these systems, the repulsive Coulomb interactions lead to ...
Researchers at Peking University and collaborators have revealed evidence of Mott insulator with thermally induced melting ...
The extended Su–Schrieffer–Heeger (SSH) tight-binding model was employed to accurately elucidate the electron transport behavior in donor polymer. The time evolutions of net charges on each site shown ...
In a study published in Nature Materials, a research team from the National University of Singapore (NUS) achieved a significant breakthrough by generating and directly observing electron-hole ...
They then tuned down the voltage slightly, so that only one electron occupied each well in the lattice. In this "half-filled" state, the material is considered a Mott insulator -- a curious electrical ...
(Nanowerk News) New energy-efficient electronic devices may be possible thanks to research that demonstrates the quantum anomalous Hall (QAH) effect -- where an electrical current does not lose energy ...
A team developed a novel method to successfully visualise electron-hole crystals in an exotic quantum material. Their breakthrough could pave the way for new advancements in computing technologies, ...
