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.

By combining local thermodynamic and transport measurements in twisted trilayer graphene, the study reveals that superconductivity is not directly tied to correlated insulators but instead correlates closely with the strength of compressibility sawtooth features, suggesting a shared origin linked to electron-electron interactions and twist-angle-dependent band structures.
This paper reports the discovery of a distinct, intrinsic superconducting regime in pristine and lightly substituted infinite-layer PrNiO2 that is separated from the conventional doping-induced superconducting dome by a non-superconducting region, challenging the view of nickelates as simple cuprate analogs.
Using angle-resolved photoemission spectroscopy, this study reveals that infinite-layer nickelates exhibit momentum-selective marginal-Fermi-liquid-like scattering without the pseudogap formation typically seen in cuprates, suggesting that a pseudogap is not an essential prerequisite for high-temperature superconductivity.
This paper introduces ah-SCDFT, a general and efficient first-principles approach that systematically incorporates anharmonic corrections into superconducting density functional theory to achieve high-fidelity predictions of superconducting properties, as demonstrated by its accurate reproduction of MgB2 behavior under various conditions.
This paper proposes a unified symmetry-based microscopic theory explaining the lower superconducting transition temperature in LaNiO compared to LaNiO as a result of its two-gap nature, where a diminished interlayer pairing contribution dominates over the subleading intralayer pairing.
This study employs first-principles calculations combined with the stochastic self-consistent harmonic approximation to demonstrate that ionic quantum and anharmonic effects significantly stabilize the lattice of DSe down to 70 GPa, reduce its superconducting critical temperature by 3–16 K, and suppress the isotope coefficient to 0.29, thereby highlighting the critical role of anharmonicity in resolving theory-experiment discrepancies in high-pressure hydrides.
This paper establishes theoretical principles for tunable superconductivity mediated by heavy-electron plasmons, demonstrating that while plasmon-mediated pairing alone yields low transition temperatures, its synergy with phonons can boost above 20 K, and proposing that flat-band systems can serve as effective pairing mediators via interband plasmons when light and heavy electrons are engineered into distinct mirror-symmetry sectors.
This paper proposes that boundary-controlled chiral edge states in topological kagome antiferromagnets, which exhibit asymmetric spectra due to sublattice-dependent termination, serve as a simple yet overlooked mechanism for generating nonreciprocal superconducting transport phenomena such as the Josephson diode effect.
This paper proposes a unified framework describing how doping a fractional Chern insulator with leads to diverse metallic and superconducting phases, including charge- superconductors and orthogonal metals, by modeling the system through a parton construction that reveals an emergent symmetry analogous to color superconductivity in high-energy physics.
This paper demonstrates that spin-orbit-coupled nanowires proximitized to -wave altermagnets can host topological Fulde-Ferrell-Larkin-Ovchinnikov (FFLO) states via a first-order phase transition, characterized by a sharp sign reversal in the superconducting diode effect and driven by a discontinuous switch in the free energy landscape.
