Title: Pervasive electronic nematicity in a cuprate superconductor

Abstract

Here, we describe an extensive experimental study of La_2-xSr_xCuO₄ 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.

What is really extraordinary in cuprate superconductors?

Journal Article Bozovic, I. ; Wu, J. ; He, X. ; ... - Physica. C, Superconductivity

Over the course of three decades of intense study, apart from the exceptionally high critical temperature, many unusual properties of cuprates have been discovered, notably including resistivity linear in temperature, electronic Raman continuum and optical absorption extending throughout the infrared region, pseudogap, hour-glass spin excitation spectrum, etc. However, each of these features have been also observed in other materials, including some that are not even superconducting at all. Here, we describe an extensive experiment in which over 2,000 films of the La_2-xSr_xCuO₄ have been synthesized and studied in detail over the course of the last twelve years. We argue heremore »« less

Spontaneous breaking of rotational symmetry in copper oxide superconductors

Journal Article Wu, J. ; Bollinger, A. T. ; He, X. ; ... - Nature (London)

The origin of high-temperature superconductivity in copper oxides and the nature of the ‘normal’ state above the critical temperature are widely debated. In underdoped copper oxides, this normal state hosts a pseudogap and other anomalous features; and in the overdoped materials, the standard Bardeen–Cooper–Schrieffer description fails, challenging the idea that the normal state is a simple Fermi liquid. To investigate these questions, we have studied the behaviour of single-crystal La_2–xSr_xCuO₄ films through which an electrical current is being passed. Here we report that a spontaneous voltage develops across the sample, transverse (orthogonal) to the electrical current. The dependence of this voltage on probe current, temperature, in-plane device orientation and doping shows that this behaviour is intrinsic, substantial, robust and present over a broad range of temperature and doping. If the current direction is rotated in-plane by an anglemore »« less

Tracking the nematicity in cuprate superconductors: a resistivity study under uniaxial pressure

Journal Article Xie, Tao ; Liu, Zhaoyu ; Gu, Yanhong ; ... - Journal of Physics. Condensed Matter

Overshadowing the superconducting dome in hole-doped cuprates, the pseudogap state is still one of the mysteries that no consensus can be achieved. It has been suggested that the rotational symmetry is broken in this state and may result in a nematic phase transition, whose temperature seems to coincide with the onset temperature of the pseudogap statemore »« less

Electron pairing in the pseudogap state revealed by shot noise in copper oxide junctions

Journal Article Zhou, Panpan ; Chen, Liyang ; Liu, Yue ; ... - Nature (London)

In the quest to understand high-temperature superconductivity in copper oxides, debate has been focused on the pseudogap—a partial energy gap that opens over portions of the Fermi surface in the ‘normal’ state above the bulk critical temperature. The pseudogap has been attributed to precursor superconductivity, to the existence of preformed pairs and to competing orders such as charge-density waves. A direct determination of the charge of carriers as a function of temperature and bias could help resolve among these alternatives. Here we report measurements of the shot noise of tunnelling current in high-quality La_2-xSr_xCuO₄/La₂CuO₄/La_2-xSr_xCuO₄ (LSCO/LCO/LSCO) heterostructures fabricated using atomic layer-by-layermore »« less
