A State of High Tc Superconductivity There are strong indications that high-temperature superconductivity in the cuprates is formed amid competing orders, but only two have been observed unambiguously. The so-called stripe order has been observed in a Lanthanum-based cuprate family and consists of coexisting charge-and-spin modulations and occurs at a characteristic dopant concentration in which the critical temperature Tc has a dip. Now, Ghiringhelli et al. (p. 821, published online 12 July… 
Uniaxial pressure control of competing orders in a high-temperature superconductor
TLDR
A high-resolution inelastic x-ray scattering study of the high-temperature superconductor YBa2Cu3O6 under uniaxial stress is reported and a three-dimensional long-range-ordered CDW state can be induced through pressure along the a axis, in the absence of magnetic fields.
Angular Fluctuations of a Multicomponent Order Describe the Pseudogap of YBa2Cu3O6+x
TLDR
A theory is proposed in which the superconducting and charge-density wave orders exhibit angular fluctuations in a six-dimensional space that provides a natural quantitative fit to the x-ray data and can be a basis for understanding other characteristics of the pseudogap.
Stabilization of three-dimensional charge order in YBa2Cu3O6+x via epitaxial growth
TLDR
Three-dimensional charge order can be stabilized in YBCO films and studied without using the high magnetic fields that are necessary in the bulk material, and thus efficiently transmit CO correlations between adjacent CuO2 bilayer units.
Ubiquitous Interplay Between Charge Ordering and High-Temperature Superconductivity in Cuprates
TLDR
This work used scanning tunneling microscopy and resonant elastic x-ray scattering measurements to establish the formation of charge ordering in the high-temperature superconductor Bi2Sr2CaCu2O8+x, indicating the similarity of charge organization competing with superconductivity across different families of cuprates.
Competing charge, spin, and superconducting orders in underdoped YBa2Cu3Oy
To explore the doping dependence of the recently discovered charge-density-wave (CDW) order in YBa2Cu3Oy, we present a bulk-sensitive high-energy x-ray study for several oxygen concentrations,
Coherent charge and spin density waves in underdoped HgBa2CuO4+δ
Charge order in cuprate superconductors appears to be a universal characteristic, often associated with pseudogap behavior in the normal state. The central question is whether such charge ordering or
Quasiparticle Coherence, Collective Modes, and Competing Order in Cuprate Superconductors
In recent years, the study of cuprate superconductors has been dominated by the investigation of normal state properties. Of particular interest is the nature of interactions between
Fluctuating charge-density waves in a cuprate superconductor.
TLDR
A method based on ultrafast spectroscopy to detect the presence and measure the lifetimes of CDW fluctuations in cuprates and forges a path for studying fluctuating order parameters in various superconductors and other materials.
Incipient charge order observed by NMR in the normal state of YBa 2 Cu
The pseudogap regime of high-temperature cuprates harbours diverse manifestations of electronic ordering whose exact nature and universality remain debated. Here, we show that the short-ranged charge
Spectroscopic Evidence for Charge Order Melting via Quantum Fluctuations in a Cuprate
Copper-oxide high TC superconductors possess a number of exotic orders co-existing with or proximal to superconductivity, whose quantum fluctuations may account for the unusual behaviors of the

Magnetic-field-induced charge-stripe order in the high-temperature superconductor YBa2Cu3Oy
TLDR
Nuclear magnetic resonance measurements are reported showing that high magnetic fields actually induce charge order, without spin order, in the CuO2 planes of YBa2Cu3Oy, and it is argued that it is most probably the same 4a-periodic modulation as in stripe-ordered copper oxides.
Two-dimensional geometry of spin excitations in the high-transition-temperature superconductor YBa2Cu3O6+x
TLDR
It is demonstrated that the geometry of the magnetic fluctuations is two-dimensional, and Rigid stripe arrays appear to be ruled out over a wide range of doping levels in YBa2Cu3O6+x, but the data may be consistent with liquid-crystalline stripe order.

TLDR
It is concluded that the pseudogap phase is an electronic state that strongly breaks four-fold rotational symmetry, which narrows the range of possible states considerably, pointing to stripe or nematic order.
