Alternate cleavage structure and electronic inhomogeneity in Ca-doped YBa $_2$ Cu $_3$ O $_{7-δ}$

By combining scanning tunneling microscopy and density functional theory, this study demonstrates that 10% Ca-doping at the Y site in YBa $_2$ Cu $_3$ O $_{7-δ}$ 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.

The dual Ginzburg-Landau theory for a holographic superconductor: Finite coupling corrections

This paper derives the exact dual Ginzburg-Landau theory for a minimal holographic superconductor at finite coupling, revealing that the GL parameter increases (making the system more Type-II) and the condensate rises, while correcting previous misconceptions regarding the AdS/CFT dictionary and condensate determination.

Two-dimensional flat band on the (011) surface of UTe $_2$ : Implication for STM measurements with a superconducting tip

This paper theoretically demonstrates that a two-dimensional nearly flat band on the (011) surface of UTe $_2$ , arising from nontrivial Berry phases and weak spin conservation in the $B_{3u}$ state, explains the zero-bias peak observed in STM experiments with superconducting tips and offers crucial insights into the material's superconducting pairing symmetry.

Magnetic penetration depth in topological superconductors: Effect of Majorana surface states and application for UTe $_2$

This study demonstrates that magnetic penetration depth measurements in UTe $_2$ can directly probe Majorana surface states and distinguish between different topological pairing symmetries, as surface contributions dominate the low-temperature $T^n$ scaling behavior in low- $\kappa$ superconductors while bulk quasiparticles govern the response in high- $\kappa$ regimes.

Superconductivity as a Probe of Altermagnetism: Critical Temperature, Field, and Current

This paper utilizes Ginzburg-Landau theory to demonstrate that the coexistence of $d$ -wave altermagnetism and superconductivity in thin films produces characteristic fourfold anisotropies in critical temperature, parallel critical field, and critical current density, providing experimentally accessible signatures for detecting altermagnetism.
