Signatures of Topological Superconductivity and Josephson Diode Effects on the Magnetocurrent-Phase Relation of Planar Josephson Junctions

This paper theoretically demonstrates that magneto-current-phase relation measurements in proximitized planar Josephson junctions serve as a versatile spectroscopic tool to reconstruct ground-state phases, quantify Rashba spin-orbit coupling, diagnose topological gap closings, and characterize the Josephson diode effect.

Enhancement of metallicity by Na doping in La3_3Ni2_2O7+δ_{7+δ}

This study demonstrates that sodium doping in La3_3Ni2_2O7+δ_{7+\delta} induces a structural phase transition and significantly enhances metallicity while suppressing the density wave transition, offering key insights into tuning competing electronic phases in layered nickelates.

On the estimating the superconducting volume fraction from the internal magnetic susceptibility

This paper challenges the widely used postulate that the superconducting volume fraction equals the amplitude of internal magnetic susceptibility, arguing that this relationship is incorrect and citing a specific counterexample in pressurized Pr4Ni3O10Pr_4Ni_3O_{10} to call for a reevaluation of the methodology across the entire field of superconductivity.

Discovery of intertwined pair density and charge density wave orders in UTe2

Using vector magnetic field scanning tunneling microscopy, researchers discovered that UTe2 hosts intertwined pair density wave and charge density wave orders, where distinct modulations emerge above and below the critical temperature, establishing the material as a unique platform for directly resolving the fundamental and emergent manifestations of triplet PDW physics.

Alternate cleavage structure and electronic inhomogeneity in Ca-doped YBa2_2Cu3_3O7−δ_{7-δ}

By combining scanning tunneling microscopy and density functional theory, this study demonstrates that 10% Ca-doping at the Y site in YBa2_2Cu3_3O7−δ_{7-δ} induces an alternate cleavage plane that preserves bulk-like electronic properties, enabling the first direct observation of nanoscale superconducting gap inhomogeneity in the YBCO family.

Paramagnon-Interference Mechanism for Three-Dimensional Bond Order in Kagome Metals AV3_3Sb5_5 (A=Cs, Rb, K): Analysis by the Density-Wave Equation

This paper establishes that the paramagnon-interference mechanism drives the emergence of a commensurate 3D 2×2×22\times 2\times 2 bond order in kagome metals AV3_3Sb5_5, with the specific stacking pattern determined by the third-order Ginzburg-Landau term and the quasi-2D nature of the Fermi surface.
