Spin density wave rather than tetragonal structure is prerequisite for superconductivity in La3Ni2O7-δ [PDF]

Nature Communications
The pressure-induced high-temperature (T c ) superconductivity in nickelates La3Ni2O7-δ has sparked significant interest to explore its superconductivity at ambient pressure.

Coupled ferroelectricity and superconductivity in bilayer T_d-MoTe_2 [PDF]

Nature, 2023
The authors show a hysteretic behaviour of superconductivity as a function of electric field in bilayer Td-MoTe_2, representing observations of coupled ferroelectricity and superconductivity.

Coexistence of superconductivity with partially filled stripes in the Hubbard model [PDF]

Science, 2023
The Hubbard model is an iconic model in quantum many-body physics and has been intensely studied, especially since the discovery of high-temperature cuprate superconductors.

High-temperature superconductivity with zero resistance and strange-metal behaviour in La3Ni2O7−δ [PDF]

Nature Physics, 2023
Recent experimental observations have showed some signatures of superconductivity close to 80 K in La3Ni2O7 under pressure and have raised the hope of achieving high-temperature superconductivity in bulk nickelates. However, a zero-resistance state—a key

Shielding Characteristics of Solenoidal Superconducting Screens Made From HTS Tape, for SFCL Applications

IEEE Access, 2023
In the design and prototyping of an Inductive-Resistive Superconductor Fault Current Limiter (IR-SFCL), previously presented by the authors, superconducting screens made from BSCO bulk have been used for shielding the inductive stage of the device.

Absence of near-ambient superconductivity in LuH2±xNy [PDF]

Nature, 2023
Nitrogen-doped lutetium hydrides LuH_2± x N_ y synthesized using a high-pressure and high-temperature synthesis technique did not show near-ambient superconductivity at pressures below 40.1 GPa.

Unconventional superconductivity in magic-angle graphene superlattices [PDF]

Nature, 2018
The behaviour of strongly correlated materials, and in particular unconventional superconductors, has been studied extensively for decades, but is still not well understood.

Evidence for charge delocalization crossover in the quantum critical superconductor CeRhIn5

Nature Communications, 2023
The nature of charge degrees-of-freedom distinguishes scenarios for interpreting the character of a second order magnetic transition at zero temperature, that is, a magnetic quantum critical point (QCP).

Effect of heat treatments on superconducting properties and connectivity in K-doped BaFe2As2

Scientific Reports, 2021
Fe-based superconductors and in particular K-doped BaFe2As2 (K-Ba122) are materials of interest for possible future high-field applications. However the critical current density (J c ) in polycrystalline Ba122 is still quite low and connectivity issues ...
