Non‐Fermi‐Liquid Behavior of Superconducting SnH4

open access: yesAdvanced Science, 2023
The chemical interaction of Sn with H2 by X‐ray diffraction methods at pressures of 180–210 GPa is studied. A previously unknown tetrahydride SnH4 with a cubic structure (fcc) exhibiting superconducting properties below TC = 72 K is obtained; the ...

A study of superconductivity in single crystals and thin films using muon-spin rotation and neutron scattering [PDF]

open access: yes, 2009
The archetypal high temperature superconductor Bi₂Sr₂CaCu₂O[subscript[8+δ]] has been extensively investigated. However, until now, little has been known about the behaviour of the magnetic vortices inside the Vortex Glass and liquid state.

Superconductivity up to 243 K in the yttrium-hydrogen system under high pressure

open access: yesNature Communications, 2021
The discovery of high temperature superconductivity in hydrogen-rich compounds stimulates further extensive studies. Here, the authors report superconductivity in pressurized yttrium-hydrogen system with highest predicted T c among binary compounds.

Control of Superconductivity in Cuprate/Manganite Heterostructures [PDF]

open access: yes, 2004
Research has shown that the spin alignment in an adjacent ferromagnet is capable of suppressing superconductivity. In this project, devices incorporating cuprate/manganite heterostuctres were successfully fabricated to study the effects of spin ...

High-temperature phonon-mediated superconductivity in monolayer Mg2B4C2

open access: yesnpj Quantum Materials, 2022
A two-dimensional material – Mg2B4C2, belonging to the family of the conventional superconductor MgB2, is theoretically predicted to exhibit superconductivity with critical temperature T c estimated in the 47–48 K range (predicted using the McMillian ...

High-temperature superconductivity [PDF]

open access: yesBrazilian Journal of Physics, 2003
The widely held notion that high-temperature superconductivity originates in the cuprate-planes is proven to be faulty. In the cuprates such as YBa2Cu3O7, we argue that the superconductivity resides in the BaO layers. This superconductivity is s-wave, not d-wave, in the bulk.

Unified Pressure and Field Response Across Distinct Charge‐Order Regimes in Ti‐Doped CsV3Sb5

open access: yesAdvanced Functional Materials, EarlyView.
We microscopically investigate the interplay between charge order and superconductivity in a kagome superconductor across regimes of long‐ and short‐range charge order. Hydrostatic‐pressure and magnetic‐field μSR$\mu{\rm SR}$ measurements reveal remarkably similar superconducting and normal‐state time‐reversal‐symmetry‐breaking responses in both ...

Gutzwiller-RVB theory of high temperature superconductivity : results from renormalized mean field theory and variational Monte Carlo calculations [PDF]

open access: yes, 2007
We consider the theory of high temperature superconductivity from the viewpoint of a strongly correlated electron system. In particular, we discuss Gutzwiller projected wave functions, which incorporate strong correlations by prohibiting double occupancy
