Theoretical predictions of electronic materials and their properties

In this article, I first define the basic structure of modern ‘first-principles theory of real materialsʹ (including old references), and then I review recent applications to electronic materials. I argue that electronic structure theory of real materials has advanced to the point where bold predictions of yet unmade materials and of unsuspected physical properties are being made, fostering a new type of interaction with experimentalists. I review the basic characteristics of this new style of theory, illustrating a few recent applications, and express opinions as to future challenges.
