Gapless Superconductivity From Extremely Dilute Magnetic Disorder in 2H‐NbSe2‐xSx

open access: yesAdvanced Materials, EarlyView.
We demonstrate that 2H‐NbSe2‐xSx hosts gapless superconductivity at unexpectedly low magnetic impurity concentrations. Combining STM, Bogoliubovde Gennes simulations, DFT, and quasiparticle interference, we comprehensively study the development of gapless behavior and show that SeS substitution reshapes the band structure, enhances nesting, and drives ...

High- superconductor candidates proposed by machine learning

open access: yesMachine Learning: Science and Technology
We cast the relation between the chemical composition of a solid-state material and its superconducting critical temperature ( $T_\mathrm c$ ) as a statistical learning problem with reduced complexity.

Towards Ginzburg–Landau Bogomolny Approach and a Perturbative Description of Superconducting Structures

open access: yesQuantum Reports
The Bogomolny approach to the Ginzburg–Landau equations in the context of strong and semi-strong necessary conditions is formulated for various superconducting structures in a quasi-one-dimensional description, considering both flat and curved geometries.

Surface Reordering During Layer‐by‐Layer Growth on SrTiO3

open access: yesAdvanced Materials, EarlyView.
Surface structures (left) derived from DFT‐constrained fitting to crystal truncation rods measured by synchrotron X‐ray scattering (right) after each monolayer of deposition during the MBE growth of SrTiO3${\rm SrTiO}_{3}$ (001). The bottom panel shows the bare substrate, the middle panel shows island formation upon deposition of a single layer of SrO,

Nanostructured superconductors

open access: yes
The relevant length scales for superconductivity are of the order of nanometers. By confining the superconducting condensate to such dimensions, many physical properties change substantially, and novel phenomena emerge, which are absent in the pristine material.

Crossed Andreev reflection as a probe for the pairing symmetry of Ferromagnetic Superconductors

open access: yes, 2006
The coexistence of superconductivity and ferromagnetism has brought about the phenomena of ferromagnetic superconductors. The theory needed to understand the compatibility of such antagonistic phenomena cannot be built until the pairing symmetry of such ...

Signatures of Edge States in Antiferromagnetic Van der Waals Josephson Junctions

open access: yesAdvanced Materials, EarlyView.
ABSTRACT The combination of superconductivity and magnetic textures leads to unconventional superconducting phenomena, including new correlated and topological phases. Van der Waals (vdW) materials emerge as a versatile platform for exploring the interplay between these two competing orders.

High‐performance diffusion model for inverse design of high Tc superconductors with effective doping and accurate stoichiometry

open access: yesInfoMat
The pursuit of designing superconductors with high Tc has been a long‐standing endeavor. However, the widespread incorporation of doping in high Tc superconductors significantly impacts electronic structure, intricately influencing Tc.

Josephson effect in quasi one-dimensional unconventional superconductors

open access: yes, 2003
Josephson effect in junctions of quasi one-dimensional triangular lattice superconductors is discussed, where the theoretical model corresponds to organic superconductors (TMTSF)_2PF_6. We assume the quarter-filling electron band and p, d and f wave like
