Superconductivity is a fascinating state of matter where materials conduct electricity without any resistance, often defying our everyday expectations of how energy behaves. Researchers in this field explore the quantum mechanics behind these phenomena, seeking new materials that can operate at higher temperatures or under more practical conditions. This work holds the promise of revolutionizing everything from power grids to medical imaging devices, making the invisible world of quantum physics feel increasingly tangible and useful.

This paper demonstrates that coupling a kagome magnet exhibiting the quantum anomalous Hall effect to a Rashba superconductor—rather than a standard -wave superconductor—can induce topological superconducting phases characterized by odd Bogoliubov-de Gennes Chern numbers.
Using particle swarm optimization and first-principles calculations, this study identifies several thermodynamically stable Mg-Ti-H ternary hydride structures under high pressure, most notably a $P4/nmm$-MgTiH phase with a of 81.9 K and a Zr/Hf-substituted $P4/nmm$-MgHfH phase that achieves a higher of 86 K due to enhanced electron-phonon coupling.
This paper presents a systematic investigation of PrFeAsOF across the full doping range, establishing its first complete electronic phase diagram and demonstrating enhanced superconductivity with a maximum of 52.3 K and large upper critical fields.
This study reports the first observation of the topological and planar Hall effects in the metallic monoclinic van der Waals ferromagnet , identifying it as a promising platform for spintronics due to its nontrivial electronic band structure and perpendicular magnetic anisotropy.
This study demonstrates that metal encapsulation (such as gold capping) improves the superconducting properties of niobium thin films by reducing bulk disorder and scattering, suggesting that pair-breaking throughout the entire film, rather than just at the surface, is a significant source of decoherence in transmon qubits.
The paper analyzes SR data for () and concludes that the results support a coplanar spin spiral within the plane rather than a spin stripe model.
This paper introduces a novel SQUID-based microcalorimeter concept that utilizes the temperature-dependent magnetic penetration depth of a superconductor for mutual inductance readout, offering tunable signal amplification and a potential pathway toward achieving sub-100 meV energy resolution for high-precision X-ray spectroscopy.
This paper provides experimental evidence of a direct correlation between superconductivity and antiferromagnetic spin fluctuations in thin films, identified through a unique "Mexican hat"-shaped magnetoresistance.
Using polarization-resolved electronic Raman scattering, this study demonstrates that the spin-density-wave state in is driven by anisotropic electronic correlations with momentum-selective gap amplitudes.
Using ultrasound-propagation measurements under various conditions, this study suggests that the multi-phase superconductivity in arises from single-component order parameters driven by local non-centrosymmetry, while phase I is characterized by an incommensurate magnetic order.
