Suppression of spectral gap and flat bands on a cuprate superconductor side-surface

Abstract Side surfaces of cuprate superconductors are expected to display a suppressed d -wave order parameter and zero-energy topological flat bands with a large density of states, making them susceptible to symmetry broken orders. Yet such surfaces have never been investigated...

Substrate tuning of the structural and electronic transition in thin flakes of the excitonic insulator candidate Ta2NiSe5

Abstract Ta 2 NiSe 5 continues to draw interest for its T c = 326 K phase transition, whose dual electronic and structural nature reflects a complex interplay of electron-hole (excitonic) and electron-lattice interactions. The majority of studies that have attempted to decipher t...
