TL;DR: In this article, density functional calculations of the electronic structure, Fermi surface, phonon spectrum, magnetism, and electron-phonon coupling for the superconducting phase FeSe, as well as the related compounds FeS and FeTe were performed.

TL;DR: The crystal structure of this exotic non-equilibrium state of YBa2Cu3O6+x is reported, determined by femtosecond X-ray diffraction and ab initio density functional theory calculations, and the enhancement in the character of the in-plane electronic structure is likely to favour superconductivity.

TL;DR: In this article, coherent optical excitation of molecular vibrations in the organic conductor K3C60 can induce a non-equilibrium state with the optical properties of a superconductor, and a transient gap in the real part of the optical conductivity and a low-frequency divergence of the imaginary part are measured for base temperatures far above equilibrium Tc=20 K.

TL;DR: In this paper, anisotropic changes in the buckling of the inplane Cu-O bonds are found, which may perturb the charge density wave order that is believed to compete with superconductivity.

TL;DR: A microscopic theory for ultrafast control of solids with terahertz optical pulses accounts for a light-induced insulator-to-metal transition as mentioned in this paper, which is the basis for our work.
