This paper employs a tight-binding lattice model to investigate the gap structure and phase diagram of twisted bilayer cuprates, revealing that the time-reversal symmetry breaking state is correlated with the Van Hove singularity's position—which varies with doping and interlayer tunneling—and discussing how these findings reconcile conflicting experimental results.
This study demonstrates that while chiral molecular potentials in superconducting Josephson junctions have minimal impact on equilibrium charge supercurrents, they induce distinct, anisotropic spin-polarized supercurrents dependent on molecular handedness, thereby establishing spin-polarized Josephson interferometry as a sensitive platform for detecting molecular chirality and advancing superconducting spintronics.

This paper theoretically explains the rapid growth and subsequent plateau of a specific sound wave frequency observed in nematic aerogel-filled superfluid 3He by modeling the aerogel's elastic properties and demonstrating how the hybridization of isotropic first sound, anisotropic second sound, fourth sound, and standard elastic modes leads to these distinct velocity behaviors near the polar phase transition.

This paper demonstrates a gate-switchable superconducting diode effect in lead nanoscale islands driven into the Coulomb blockade regime, where electron-electron interactions and electrostatic tuning break particle-hole symmetry to induce nonreciprocal Cooper-pair currents without requiring external magnetic fields or complex heterostructures.
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.
Using the fluctuation exchange (FLEX) approximation, this study demonstrates that the emergence of a pocket near the point in LaNiO thin films enhances -wave pairing through improved Fermi-surface nesting, suggesting a viable mechanism for boosting superconductivity under ambient pressure.
This study demonstrates that magnetic penetration depth measurements in UTe can directly probe Majorana surface states and distinguish between different topological pairing symmetries, as surface contributions dominate the low-temperature scaling behavior in low- superconductors while bulk quasiparticles govern the response in high- regimes.

This paper establishes that the paramagnon-interference mechanism drives the emergence of a commensurate 3D $2\times 2\times 2_3_5$, with the specific stacking pattern determined by the third-order Ginzburg-Landau term and the quasi-2D nature of the Fermi surface.
This study reveals that in the Janus MXene Mo2NF2, a charge density wave instability driven by momentum-dependent electron-phonon coupling competes with superconductivity, but the latter can be enhanced and the former suppressed through compressive biaxial strain, thereby establishing Mo2NF2 as a tunable platform for controlling the interplay between these two quantum phases.
