Fluctuation-enhanced electron-phonon coupling in FeSe

This study demonstrates that uniaxial strain acts as a sensitive probe in FeSe, revealing that ordering fluctuations near the nematic transition enhance electron-phonon coupling and induce a distinct two-phonon scattering anomaly in the A1gphA_{1g}^{ph} mode, which is highly dependent on the direction and magnitude of the applied strain.

Unconventional spin valve effect in altermagnets induced by Rashba spin orbit coupling and triplet superconductivity

This paper theoretically demonstrates that Rashba spin-orbit coupling in altermagnet/triplet superconductor/altermagnet junctions enables a robust, electrically tunable spin valve effect and distinct transport signatures that distinguish between nodal and chiral triplet pairing symmetries, all without requiring ferromagnetic electrodes.

Minimal loop currents in doped Mott insulators

This paper utilizes variational Monte Carlo simulations on the tt-JJ model to reveal that doped Mott insulators form "cat states" where single holes resonate between quasiparticle and minimal loop-current components, while two holes automatically fuse into tightly bound pairs that resonate between incoherent dxyd_{xy} and coherent dx2y2d_{x^2-y^2} channels, suggesting a robust mechanism for high-temperature superconductivity.

Pairing mechanism and superconductivity in pressurized La5_5Ni3_3O11_{11}

Using density functional theory and random phase approximation, this study reveals that superconductivity in pressurized La5_5Ni3_3O11_{11} primarily originates from an s±s^\pm-wave pairing mechanism within the bilayer subsystem, while the single-layer subsystem facilitates inter-bilayer coherence via weak Josephson coupling, collectively explaining the experimentally observed dome-shaped pressure dependence of the critical temperature.

Strengthened correlations near [110] edges of dd-wave superconductors in the t-J model with the Gutzwiller approximation

Using the Gutzwiller approximation within the t-J model, this study reveals that [110] edges of d-wave superconducting slabs exhibit locally strengthened correlations and reduced hopping that draw quasiparticle charge toward the boundary, thereby weakening local superconductivity, suppressing zero-energy Andreev bound states, and preventing the formation of an extended s-wave component across a wide range of hole dopings.

Spin-Valley Locking and Pure Spin-Triplet Superconductivity in Noncollinear Antiferromagnets Proximitized to Conventional Superconductors

This paper demonstrates that coupling chiral noncollinear antiferromagnets, such as Mn3_3Ge and Mn3_3Ga, with conventional superconductors induces pure spin-triplet superconductivity through a unique spin-valley locking mechanism driven by magnetic chirality, achieving a Zeeman-field-resilient state without requiring spin-orbit coupling or net magnetization.

Finite-momentum mixed singlet-triplet pairing in chiral antiferromagnets induced by even-parity spin texture

This paper demonstrates that an even-parity spin texture in chiral non-collinear antiferromagnets induces a unique finite-momentum coexistence of opposite-spin singlet and equal-spin triplet pairing without requiring net magnetization or spin-orbit coupling, offering a tunable platform for exotic superconducting states and spintronic applications.

Robust two-dimensional surface superconductivity and vortex lattice in the Weyl semimetal γγ-PtBi2_2

Using very low-temperature Scanning Tunneling Microscopy, this study confirms robust two-dimensional surface superconductivity with a critical temperature of 2.9 K and quantized vortices in the Weyl semimetal γ\gamma-PtBi2_2, demonstrating macroscopic quantum phase coherence linked to its surface Fermi arcs.

Ab initio investigation on structural stability and phonon-mediated superconductivity in 2D-hydrogenated M2X (M= Mo, V, Zr; X=C, N) MXene monolayer

This first-principles study reveals that partial hydrogenation stabilizes most 2D M2X MXene monolayers and induces strong electron-phonon coupling leading to superconductivity in Mo-based systems, while identifying Zr2CH4 as a unique dynamically stable candidate hosting Dirac-like electronic states.
