Moiré‐Induced Symmetry Breaking of Charge Order in van der Waals Heterostructures

Advanced Materials, EarlyView.
A uniaxial moiré potential in misfit (MS)1+δTaS2 heterostructures selectively reshape charge order: the embedded 1H‐TaS2 layer hosts an incommensurate charge‐density wave, fragmented into nanometer domains and stripped of threefold symmetry. Superconductivity, however, remains uniform and fully gapped, revealing heterosymmetry stacking as a selective ...

Orbital-dependent electron correlation in double-layer nickelate La3Ni2O7

Nature Communications
The latest discovery of high temperature superconductivity near 80 K in La3Ni2O7 under high pressure has attracted much attention. Many proposals are put forth to understand the origin of superconductivity. The determination of electronic structures is a

High-temperature superconductivity from realistic Coulomb and Frohlich interactions [PDF]

, 2012
In recent years ample experimental evidence has shown that charge carriers in high-temperature superconductors are strongly correlated but also coupled with lattice vibrations (phonons), signalling that the true origin of high-Tc superconductivity can ...

Gate‐Induced Critical Current Modulation in W–C Nanowires: The Role of Fabrication

Advanced Materials Technologies, EarlyView.
Focused ion beam induced deposition (FIBID) enables precise control of superconducting W–C nanowire devices. Introducing a Ga+ focused ion beam (FIB) cleaning step reduces substrate damage and suppresses leakage currents, shifting gating thresholds to higher voltages.

Aspects of Holographic Superconductivity [PDF]

, 2012
In this thesis we study two different aspects of holographic superconductivity. First we study fully backreacting Gauss-Bonnet (GB) holographic superconductors in 5 bulk spacetime dimensions. We explore the system’s dependence on the scalar mass for both

Localized Ion Irradiation Enables Topography‐Free High‐Tc Superconducting Metamaterials

Advanced Optical Materials, EarlyView.
A topography‐free oxygen ion‐irradiation strategy is demonstrated for patterning superconducting YBCO terahertz metamaterials without physical material removal. The approach preserves film integrity while enabling large spectral tunability, ultrafast optical modulation, and dual‐band resonance control, providing a scalable platform for low‐loss ...

FeSe: High-Temperature Superconductivity, Nematicity, and Electronic Structure

Успехи физики металлов, 2017
The electronic structure of FeSe—the simplest iron-based superconductor (Fe-SC)—conceals a potential of abrupt increase of superconducting tran-sition temperature realized under the pressure or in a single-layer film.

Theoretical and experimental considerations of the critical current density of DI-BiSCCO superconducting tapes as a function of magnetic field, field orientation, temperature and strain [PDF]

, 2013
The critical current density (Jc) of DI-BiSCCO superconducting tapes was measured as a function of magnetic field (B), field orientation (θ), temperature (T) and strain (e) in a 15 T split-pair horizontal superconducting magnet using probes designed and ...
