Zeitschrift für anorganische und allgemeine Chemie, Volume 651, Issue 12, August 1, 2025.The structural selectivity between the trigonal CaAl2Si2‐type and the orthorhombic BaCu2S2‐type phases is governed by the cationic‐to‐anionic radius ratio (r+/r–). This geometric criterion dictates the average ASb bond distance, which in turn limits the maximum substitution level of Sr and eventually determines the resulting phase selectivity for the ...

Modeling a striped pseudogap state
, 2010 We study the electronic structure within a system of phase-decoupled one-dimensional superconductors coexisting with stripe spin and charge density wave order.

Sachdev-Ye-Kitaev superconductivity: Quantum Kuramoto and generalized Richardson models
Physical Review Research, 2020 The Sachdev-Ye-Kitaev (SYK) model has emerged as a new paradigm of non-Fermi-liquid behavior. Here we investigate a possibility of having a superconducting off-diagonal long-range order (ODLRO) and a pseudogap phase within the SYK framework.

, 1999 Suppression of T_c in bilayer bismuth and thallium cuprates, by substitution of Co impurities at Cu sites, are taken for examination. T_c suppression data on differently doped Bi2212 and Tl2212 are analysed within the unitary pair-breaking formalism due ...

Dielectric response of Anderson and pseudogapped insulators
New Journal of Physics, 2018 Using a combination of analytic and numerical methods, we study the polarizability of a (non-interacting) Anderson insulator in one-, two-, and three-dimensions and demonstrate that, in a wide range of parameters, it scales proportionally to the square ...

Spectroscopic evidence for preformed Cooper pairs in the pseudogap phase of cuprates
, 2008 Angle-resolved photoemission on underdoped La$_{1.895}$Sr$_{0.105}$CuO$_4$ reveals that in the pseudogap phase, the dispersion has two branches located above and below the Fermi level with a minimum at the Fermi momentum.

Pseudogapping, Parallelism, and the Scope of Focus [PDF]
Syntax, 2016 AbstractIn this paper I defend a particular analysis of pseudogapping in which the focused remnant is moved by leftward A′‐movement (Jayaseelan, Gengel). Noting the superficial similarity between pseudogapping and stripping, I show that pseudogapping is much more restricted than we would expect if it were just another version of stripping, failing to ...

Unconventional Cooper pairing results in a pseudogap-like phase in s-wave superconductors
New Journal of Physics, 2015 The impact of disorder on the superconducting (SC) pairing mechanism is the centre of much debate. Some evidence suggests a loss of phase coherence of pairs while others point towards the formation of a competing phase.

Pseudogap formation of four-layer BaRuO$_3$ and its electrodynamic response changes
, 2001 We investiaged the optical properties of four-layer BaRuO$_{3}$, which shows a fermi-liquid-like behavior at low temperature. Its optical conductivity spectra clearly displayed the formation of a pseudogap and the development of a coherent peak with ...

Superconductivity: Beware of the pseudogap
NATURE PHYSICS, 2011 In the pseudogap phase of a high temperature cuprate superconductor conflicting evidence from different experiments points to a competing state or a precursor to superconductivity state. One single experiment now determines that both states exist.
