Although the highest superconducting critical temperature, T c, found in an elemental solid
at ambient pressure is 9.2 K (niobium), under the application of ultra-high pressures, several …

Two-dimensional (2D) materials and their moiré superlattices represent a new frontier for
quantum matter research due to the emergent properties associated with their reduced …

To explore the do** dependence of the recently discovered charge-density-wave (CDW)
order in YBa 2 Cu 3 O y, we present a bulk-sensitive high-energy x-ray study for several …

One of the common features of unconventional superconducting systems such as the heavy-
fermion, high transition-temperature cuprate and iron-pnictide superconductors is that the …

Explicit and implicit experimental evidence for charge density wave (CDW) presence in high‐
Tc superconducting oxides is analyzed. The theory of CDW superconductors is presented. It …

The high-pressure and high-temperature phase diagram of chromium has been investigated
both experimentally (in situ), using a laser-heated diamond-anvil cell technique coupled with …

The discovery of unconventional superconductivity often triggers significant interest in
associated electronic and structural symmetry breaking phenomena. For the infinite-layer …

In those cases where charge-stripe order has been observed in cuprates, the crystal
structure is such that the average rotational symmetry of the CuO 2 planes is reduced from …

Quantum criticality is a central concept in condensed matter physics, but the direct
observation of quantum critical fluctuations has remained elusive. Here we present an X-ray …

We use high-resolution synchrotron x-ray diffraction to uncover a second, low-temperature,
charge density wave (CDW) in TbTe 3. Its T c 2= 41.0±0.4 K is the lowest discovered so far …
