We examine key aspects of the theory of the Bardeen–Cooper–Schrieffer (BCS) to Bose–
Einstein condensation (BEC) crossover, focusing on the temperature dependence of the …

The role of inhomegeneity in determining the properties of correlated electron systems is
poorly understood because of the dearth of structural probes of disorder at the nanoscale …

Understanding the extent and role of inhomogeneity is a pivotal challenge in the physics of
cuprate superconductors. While it is known that structural and electronic inhomogeneity is …

The layered metamagnet CrSBr offers a rich interplay between magnetic, optical, and
electrical properties that can be extended down to the two‐dimensional (2D) limit. Despite …

Elastic softening in the paraelastic phases of Ba 1− x Sr x TiO 3 is largest near the transition
temperatures and decreases on heating smoothly over extended temperature ranges …

Fast and local probes, such as X-ray spectroscopy, X-ray diffraction (XRD), and X-ray
microscopy, have provided direct evidence for nanoscale phase separation in high …

Non-zero spin orbit coupling has been reported in several unconventional superconductors
due to the absence of inversion symmetry breaking. This contrasts with cuprate …

Precursor elastic effects are investigated in a displacive anharmonic spring model and
shown to extend greatly into the paraelastic phase. Weak precursor effects can be detected …

Because of its sensitivity to the instantaneous structure factor, S (Q, t= 0), Extended X-ray
Absorption Fine Structure (EXAFS) is a powerful tool for probing the dynamic structure of …

Empirical A-site cation substitution has advanced the stability and efficiency of hybrid
organic-inorganic lead halide perovskites solar cells and the functionality of X-ray detectors …
