Cuprates exhibit exceptionally strong superconductivity. To understand why, it is essential to
elucidate the nature of the electronic interactions that cause pairing. Superconductivity …

X-ray techniques have been used for more than a century to study the atomic and electronic
structure in practically any type of material. The advent of correlated electron systems, in …

The understanding of the origin of superconductivity in cuprates has been hindered by the
apparent diversity of intertwining electronic orders in these materials. We combined …

Electronic charges introduced in copper-oxide (CuO2) planes generate high-transition-
temperature (T c) superconductivity but, under special circumstances, they can also order …

The nature of the pseudogap phase of cuprate high-temperature superconductors is a major
unsolved problem in condensed matter physics. We studied the commencement of the …

The nature of the pseudogap phase of the copper oxides ('cuprates') remains a puzzle.
Although there are indications that this phase breaks various symmetries, there is no …

Evidence is mounting that charge order competes with superconductivity in high T c
cuprates. Whether this has any relationship to the pairing mechanism is unknown as neither …

We use the Nernst effect to delineate the boundary of the pseudogap phase in the
temperature-doping phase diagram of hole-doped cuprate superconductors. New data for …

Efforts to understand the microscopic origin of superconductivity in the cuprates are
dependent on knowledge of the normal state. The Hall number in the low-temperature, high …

In the underdoped regime, the cuprate high-temperature superconductors exhibit a host of
unusual collective phenomena, including unconventional spin and charge density …
