Synthesis and HRTEM Investigation of EuRbFe₄As₄ Superconductor

Nanomaterials, 2022
In the stoichiometric iron-based superconductor EuRbFe4As4, superconductivity coexists with a long-range magnetic ordering in Eu layers. Using high-resolution transmission electron microscopy (HRTEM), we observed an atomic structure of as-grown ...

Multiple Andreev reflections effect spectroscopy of LiFeAs single crystals: three superconducting order parameters and their temperature evolution

SN Applied Sciences, 2022
Highlights Three-gap superconductivity with possible momentum dependence (anisotropy) in LiFeAs. Temperature dependences of the superconducting gaps indicate a moderate interband coupling.

High-temperature superconductivity [PDF]

Brazilian 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.

Electronic structure and superconductivity of the non-centrosymmetric Sn4As3

New Journal of Physics, 2020
In a superconductor that lacks inversion symmetry, the spatial part of the Cooper pair wave function has a reduced symmetry, allowing for the mixing of spin-singlet and spin-triplet Cooper pairing channels and thus providing a pathway to a non-trivial ...

Pressure induced superconductivity in MnSe

Nature Communications, 2021
Superconductivity in FeSe attracted great interests to understand the mechanism of high temperature superconductivity. Here, the authors report a pressure induced superconductivity with a highest T c of ~9 K in MnSe.

High-Temperature Anyon Superconductivity [PDF]

, 1996
The screening of an applied magnetic field in the charged anyon fluid at finite density and temperature is investigated. For densities typical of high-temperature superconducting materials we find that the anyon fluid exhibits a superconducting behavior ...

Projected BCS theory for the unification of antiferromagnetism and strongly correlated superconductivity

Physical Review Research, 2022
A close connection between antiferromagnetism and superconductivity is at the core of high-temperature superconductivity. Here, we put forward the projected BCS theory for the unification of antiferromagnetism and strongly correlated superconductivity ...

High Temperature Superconductivity: Ineluctable Complexity [PDF]

, 2013
The discovery of charge-density-wave order in the high-temperature superconductor YBa$_2$Cu$_3$O$_{6+y}$ places charge order centre stage with superconductivity, suggesting they they are intertwined rather than competing.Comment: 3 pages, 1 figure, 19 ...

Mechanism of High-Temperature Superconductivity in Correlated-Electron Systems

Condensed Matter, 2019
It is very important to elucidate the mechanism of superconductivity for achieving room temperature superconductivity. In the first half of this paper, we give a brief review on mechanisms of superconductivity in many-electron systems.
