Hole-Doping Suppresses Competing Magnetism in High-DOS C136 Carbon Schwarzite: A Computational Route Toward Superconductivity in Negative-Curvature Carbon Networks

This computational study demonstrates that hole doping in D-type C136 carbon schwarzite effectively suppresses its intrinsic competing magnetic instability while preserving a high-density-of-states metallic electronic structure, thereby establishing a viable pathway for future investigations into superconductivity in negative-curvature carbon networks.

Apparent double-TcT_c from a single BKT transition in anisotropic phase-only models

This paper demonstrates that apparent double-transition temperatures observed in transport experiments on anisotropic two-dimensional superconductors can arise as artifacts of finite-size and finite-current effects in a single BKT transition, implying that robust splittings observed in real materials like KTaO3_3 interfaces must stem from physics beyond this minimal anisotropic baseline.

Freestanding GdBa2Cu3O7 Thin Films via Optimized Buffer Layer Design: Preserving Superconducting Properties

This study demonstrates that optimizing the buffer layer design, specifically using a LaAlO3/SrTiO3 bilayer, is essential for fabricating high-quality freestanding GdBCO thin films that retain their epitaxial structure and superconducting transition temperature of approximately 92 K after the lift-off process.

Anomalous and diode Josephson effect in junctions with inhomogeneous ferromagnetic barrier and interfacial Rashba spin-orbit coupling

This paper theoretically investigates the anomalous and diode Josephson effects in planar two-dimensional junctions with inhomogeneous ferromagnetic barriers and interfacial Rashba spin-orbit coupling, identifying the symmetry-breaking conditions required for these phenomena and demonstrating through numerical calculations that tuning magnetic fields, spin-orbit coupling, and superconducting order parameter orientations can significantly enhance nonreciprocal transport.

Engineering Helical Superconductors with Multiple Majorana Kramers Pairs via Higher-Order Rashba Spin-Orbit Coupling

This paper demonstrates that incorporating higher-order Rashba spin-orbit coupling, particularly cubic terms, into bilayer superconductors enables the engineering of helical topological superconductors with multiple Majorana Kramers pairs and large mirror Chern numbers, thereby overcoming the traditional limitations of Z2\mathbb{Z}_2 classification and the odd-Fermi-surface criterion.

High Temperature Superconductivity Dominated by Inner Underdoped CuO2_2 Planes in Quadruple-Layer Cuprate (Cu,C)Ba2_2Ca3_3Cu4_4O11+δ_{11+δ}

Using angle-resolved photoemission spectroscopy on the high-TcT_{\mathrm{c}} quadruple-layer cuprate (Cu,C)Ba2_2Ca3_3Cu4_4O11+δ_{11+\delta}, this study reveals that superconductivity is driven primarily by underdoped inner CuO2_2 planes rather than a composite effect involving outer planes, demonstrating that high transition temperatures can be achieved even in apical-oxygen-free, deeply underdoped layers.
