In two dimensions, quenched disorder always rounds transitions involving the breaking of spatial symmetries so, in practice, it can often be difficult to infer what form the symmetry breaking would take in the ``ideal,'' zero disorder limit. We discuss methods of data analysis which can be useful for making such inferences, and apply them to the problem of determining whether the preferred order in the cuprates is ``stripes'' or ``checkerboards.'' In many cases we show that the experiments… Expand

Photoemission signatures of valence-bond stripes in cuprates: Long-range vs. short-range order
Abstract Recent experiments indicate that the tendency toward the formation of unidirectional charge density waves (“stripes”) is common to various underdoped cuprates. We discuss momentum-resolvedExpand
Pinning of Stripes by Local Structural Distortions in Cuprate High-Tc Superconductors

Quenched disorder and vestigial nematicity in the pseudogap regime of the cuprates
It is shown that any discrete symmetry-breaking aspect of the charge order—nematicity in the case of the unidirectional CDW the authors consider explicitly—generically survives up to a nonzero critical disorder strength. Expand
Disorder induced stripes in d-wave superconductors
Stripe phases are observed experimentally in several copper- based high-Tc superconductors near 1/8 hole doping. However, the specific characteristics may vary depending on the degree of dopantExpand

Charge ordering in high-temperature superconductors visualized by scanning tunneling microscopy.
STM imaging of different families of cuprates over a wide range of doping levels reveal similar checkerboard-like patterns, indicating that such a charge ordered state is likely a ubiquitous and intrinsic characteristic of cuprate superconductors, which may shed light on understanding the mechanism of high-temperature superconductivity.
