Abstract

A different stripe The nature of superconductivity in simple metals is well understood, but standard theory fails to explain key properties of the high-temperature copper-oxide superconductors. Inelastic neutron scattering measurements now reveal unconventional behaviour of the lattice vibrations in copper-oxide superconductors, resulting in extensive electron-phonon coupling. This favours a model in which carriers bunch up to form rivers of charge — a so-called ‘stripe’ phase — though their contribution to the superconducting state is unclear.
