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.

Microscopic origin of the nemato-elastic coupling and dynamics of hybridized collective nematic-phonon excitations

This paper develops a microscopic formalism to demonstrate how impurity-enabled electron-phonon coupling generates hybridized, massless nemato-elastic collective modes near a nematic quantum critical point, revealing a complex landscape of underdamped and overdamped dynamics with significant implications for nematic-fluctuation-mediated superconductivity.

Andreev bound state spectroscopy of a quantum-dot-based Aharonov-Bohm interferometer with superconducting terminals

This paper analytically and numerically demonstrates that a quantum-dot-based Aharonov-Bohm interferometer with superconducting terminals is spectrally equivalent to a simpler side-coupled system, revealing how geometric factors and side-mode competition govern Andreev bound state spectra and induce a Josephson diode effect.

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.

Possible Enhancement of Superconductivity in Ambient-Pressure La $_3$ Ni $_2$ O $_7$ Thin Film

Using the fluctuation exchange (FLEX) approximation, this study demonstrates that the emergence of a $\delta$ pocket near the $\Gamma$ point in La $_3$ Ni $_2$ O $_7$ thin films enhances $s_{\pm}$ -wave pairing through improved Fermi-surface nesting, suggesting a viable mechanism for boosting superconductivity under ambient pressure.

Evolution of the Superfluid Density in Infinite-Layer Nickelates

This study reveals that the superconducting transition temperature in infinite-layer nickelates is limited by superconducting phase fluctuations, evidenced by a weak superfluid stiffness scaling with the square root of $T_\mathrm{c}$ and a significant suppression of superfluid density driven by the strong coupling between Nd magnetism and the superconducting condensate.

Moiré-induced symmetry breaking of charge order in van der Waals heterostructures

This study demonstrates that stacking misfit layered chalcogenides with 1H-TaS $_2$ induces anisotropic symmetry breaking in the charge-density wave state through a nonlinear coupling with the uniaxial moiré potential, while leaving the material's s-wave superconductivity largely unaffected.
