Title: Pervasive electronic nematicity in a cuprate superconductor

Abstract

Here, we describe an extensive experimental study of La 2-xSr xCuO 4 films synthesized by molecular beam epitaxy and investigated by angle-resolved measurements of transverse resistivity (without applied magnetic field). The data show that an unusual metallic state, in which the rotational symmetry of the electron fluid is spontaneously broken, occurs in a large temperature and doping region. The superconducting state always emerges out of this nematic metal state.
