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 pseudogap regime of high-temperature cuprates harbours diverse manifestations of
electronic ordering whose exact nature and universality remain debated. Here, we show that …

We review the intermediate coupling model for treating electronic correlations in the
cuprates. Spectral signatures of the intermediate coupling scenario are identified and used …

Charge-ordered ground states permeate the phenomenology of 3d-based transition metal
oxides, and more generally represent a distinctive hallmark of strongly correlated states of …

The identity of the fundamental broken symmetry (if any) in the underdoped cuprates is
unresolved. However, evidence has been accumulating that this state may be an …

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

We analyze incommensurate charge-density-wave (CDW) and pair-density-wave (PDW)
orders with transferred momenta (±Q, 0)/(0,±Q) in underdoped cuprates within the spin …

Establishing the presence and the nature of a quantum critical point in their phase diagram
is a central enigma of the high-temperature superconducting cuprates. It could explain their …

Motivated by recent experimental evidence of charge order in the pseudogap phase of
cuprates, we perform a variational analysis of spin-singlet density wave ordering in metals …

Recent experiments in the underdoped regime of the hole-doped cuprates have found
evidence for an incommensurate charge density-wave state. We present an analysis of the …
