Correlations among T<sub>c</sub>, A, and Γ <sub>ο</sub> within FL region of T-p phase diagram of heavy-Fermion superconductors Open
Extensively reported experimental observations indicate that on varying a control parameter, such as pressure p, within the phase diagram of most quantum critical heavy fermion HF superconductors, one identifies a cascade of distinct elect…

Structural Metastability and Fermi Surface Topology\nof SrAl<sub>2</sub>Si<sub>2</sub> Open
SrAl2Si2 crystallizes into either a semimetallic,\nCaAl2Si2-type, α phase or a superconducting,\nBaZn2P2-type, β phase. We explore possible α→Pc,Tcβ transformations by employing pressure-\nand temperature-dependent free-energy calculation…

Correlation between normal and superconducting states within the Fermi-liquid region of the $\textit{T-p}$ phase diagram of quantum-critical heavy-Fermion superconductors Open
Extensively reported experimental observations indicate that on varying pressure ($p$) within the $\textit{T-p}$ phase diagram of most quantum critical heavy fermion (HF) superconductors, one identifies a cascade of distinct electronic sta…

Superconductivity, Fermi-liquid transport, and universal kinematic scaling relation for metallic thin films with stabilized defect complexes Open
Identifying universal scaling relations between two or more variables in a\ncomplex system plays a pivotal role in understanding various phenomena in\ndifferent branches of science. Examples include the allometric scaling among\nfood webs …

Influence of substitution, nonstoichiometry and annealing-conditions on superconductivity and normal conductivity of Fe<sub>1+<i>δ</i></sub>(Te<sub>1−<i>x</i></sub><i>X<sub>x</sub></i>) (<i>X</i>=Se, S) Open
Thermal evolution of resistivity, ρ(T, x), of as-prepared samples of Fe1+δTe1−xSx (δ ≈ 0, x ≤ 0.2 = solubility limit) demonstrate a granular log-in-T character within Ts < T <300K, a Kondo-like resistive contribution within Tc < T < Ts and…

Correlation of<i>T<sub>c</sub></i>and coefficient of<i>T</i><sup>2</sup>resistivity term of Fe-based pnictide & chalcogenide superconductors Open
Normal-state of many Fe-based pnictides and chalcogenides superconductors exhibit a quadratic-in-temperature, ρtot – ρo – ρph = AT2, over wide ranges of temperature and pressure. Moreover, these systems exhibit a correlation between their …

Phase-Separation Control of K<i><sub>x</sub></i>Fe<sub>2−</sub><i><sub>y</sub></i>Se<sub>2</sub> Superconductor through Rapid-Quenching Process Open
K$_x$Fe$_{2-y}$Se$_2$ exhibits an iron-vacancy ordering at $T_{\\rm s}\n{\\sim}270{\\deg}$C and separates into two phases: a minor superconducting\n(iron-vacancy-disordered) phase and a major non-superconducting\n(iron-vacancy-ordered) pha…

Enhanced superconductivity, Kondo behavior, and negative-curvature resistivity of oxygen-irradiated thin films of aluminium Open
We followed the evolution of the normal and superconducting properties of Al\nthin films after each session of various successive oxygen irradiations at\nambient temperature. Such irradiated films, similar to the granular ones,\nexhibit en…
