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 employing a multi-stage approach combining machine learning and ab initio methods to screen the GNoME database, researchers identified 25 thermodynamically stable cubic hydrides at ambient pressure with superconducting critical temperatures up to 17 K, offering experimentally accessible candidates for high-temperature superconductivity despite their modest values.
This paper proposes that nodeless altermagnets, which possess zero net magnetization, serve as ideal platforms for generating robust, spin-polarized Josephson supercurrents mediated exclusively by triplet Cooper pairs, enabling unique 0– transitions and state crossovers through interface and orientation control.
This paper proposes a generic approach using spontaneous symmetry breaking to construct 3D lattice models that evade the no-go theorem and yield a single Weyl fermion in the infrared limit, demonstrating that these models form an equivalent class with gapless superconductors and superfluids across three distinct symmetry-breaking pathways.
This paper proposes minimizing a logarithmically compressed variance of local energies, rather than the standard mean local energy, to significantly improve the convergence and stability of neural-network wave functions when determining quantum many-body states.
This study utilizes first-principles calculations to demonstrate that hydrostatic pressure and biaxial compressive strain both suppress octahedral tilts in the hybrid bilayer-trilayer nickelate LaNiO to stabilize a tetragonal structure, yet they induce distinct electronic behaviors by causing the trilayer band to cross the Fermi level under pressure while keeping it below the Fermi level under strain.
By using molecular beam epitaxy and post-growth Te annealing to remove interstitial iron atoms, researchers demonstrated that stoichiometric FeTe is inherently a superconductor with a critical temperature of ~13.5 K, overturning the long-held view that it is an antiferromagnetic metal.
Using World-Line Monte Carlo simulations and finite-size scaling analysis, this study demonstrates that the dissipation-driven Schmid transition in a quantum Brownian particle within an Ohmic environment belongs to the Berezinskii-Kosterlitz-Thouless universality class, while revealing that this critical behavior is absent in both sub- and super-Ohmic regimes where the periodic potential fails to alter localization properties.
This paper proposes a novel scheme using cascaded Josephson-photonics devices to achieve highly efficient, near-projective stroboscopic detection of itinerant microwave single photons with low dark counts, potentially reaching near-unity efficiency through photon multiplication.
This paper demonstrates that the unusual superconducting phase in rhombohedral graphene, often interpreted as chiral topological superconductivity, is mathematically equivalent to an ordinary chiral topological superconductor on a triangular lattice that simultaneously forms a Majorana crystal on the dual honeycomb lattice.
Using density functional theory, this study reveals that epitaxial tensile strain on LaNiO films induces a high-pressure-like Fermi surface topology with significantly enhanced spin fluctuations, offering a promising pathway to achieve superconductivity without external pressure.
