Journal ArticleDOI
Nonlinear lattice dynamics as a basis for enhanced superconductivity in YBa2Cu3O6.5.
Roman Mankowsky,Roman Mankowsky,Alaska Subedi,Michael Först,S. O. Mariager,Matthieu Chollet,Henrik T. Lemke,Jeffrey S. Robinson,James M. Glownia,Michael P. Minitti,Alex Frano,Michael Fechner,Nicola A. Spaldin,Toshinao Loew,Bernhard Keimer,Antoine Georges,Antoine Georges,Antoine Georges,Andrea Cavalleri +18 more
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.
Journal ArticleDOI
Ultrafast X-rays determine the optically induced lattice distortions that transiently enhance superconducting transport in YBa2Cu3O6.5

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.
Journal ArticleDOI
Ultrafast Reversal of the Ferroelectric Polarization.
TL;DR: The demonstration of ultrafast optical reversal of the ferroelectric polarization in LiNbO_{3} is reported, as revealed by time-resolved, phase-sensitive, second-harmonic generation.
Journal ArticleDOI
Probing the interatomic potential of solids with strong-field nonlinear phononics
A. von Hoegen,Roman Mankowsky,Michael Fechner,Michael Först,Andrea Cavalleri,Andrea Cavalleri +5 more
TL;DR: An order-of-magnitude increase in field strength is achieved and higher-order phonon nonlinearities are explored in the ferroelectric material lithium niobate to benefit many aspects of materials research, including the study of classical and quantum phase transitions.
