Abstract

Femtosecond X-ray diffraction and ab initio density functional theory calculations are used to determine the crystal structure of YBa2Cu3O6.5 undergoing optically driven, nonlinear lattice excitation above the transition temperature of 52 kelvin, under which conditions the electronic structure of the material changes in such a way as to favour superconductivity.
