TL;DR: Evidence from angle-resolved photoemission spectroscopy for negative electronic compressibility (NEC) in the quasi-three-dimensional (3D) spin-orbit correlated metal (Sr1-xLax)3Ir2O7 points to a distinct pathway towards an uncharted territory of NEC featuring bulk correlated metals with unique potential for applications in low-power nanoelectronics and novel metamaterials.

TL;DR: In this article, the interplay between magnetic and structural degrees of freedom in elemental Mn is discussed, and the equilibrium volume is shown to be sensitive to magnetic interactions between the Mn atoms.

TL;DR: This work uses scanning tunneling microscopy to discover that the crucial oxygen dopants are periodically distributed in correlation with local strain in the cuprate superconductor Bi(2)Sr( 2)CaCu(2]O(8+x).
Journal ArticleDOI
Entropic Origin of Pseudogap Physics and a Mott-Slater Transition in Cuprates.
TL;DR: An order-parameter classification scheme that predicts supertransitions between families of order parameters is developed and it is found that by tuning the hopping parameters, it is possible to drive the cuprates across a transition between Mott and Slater physics, where a spin-frustrated state emerges at the crossover.
