Competition and coexistence of superconductivity and nematic order in a two-dimensional electron gas with quadrupolar interactions

This paper investigates a two-dimensional electron gas model with competing pairing and quadrupolar interactions, revealing that while nematic order strongly competes with dd-wave superconductivity to induce a first-order phase transition, it can coexist with ss-wave pairing to form an anisotropic superconducting state, with finite-temperature effects further enabling the simultaneous emergence of ss-wave, dd-wave, and nematic orders.

Stripping Symmetry: Electrochemical Oxidation to a Superconducting Polar Metal in Au2Pb0.914P2

This study demonstrates that electrochemical topotactic deintercalation of lead from the centrosymmetric parent compound Au2_2PbP2_2 induces a cooperative structural rearrangement to form the rare polar metal Au2_2Pb0.914_{0.914}P2_2, which exhibits noncentrosymmetric superconductivity below 1.52 K with a gap structure suggestive of mixed singlet-triplet pairing.

Pseudogap and Condensation in Cuprate Superconductors from NMR Shifts

This paper proposes a symmetry-based phenomenological framework for cuprate NMR data that disentangles copper shifts into two components (A and B), revealing that the pseudogap arises from their coupling and that optimal superconductivity requires a specific match between these components, while the highest transition temperatures are determined by nuclear relaxation and charge sharing rather than shift data alone.

Unveiling the Superconducting Ground State of Heusler alloy Pd2ZrIn via muon spin relaxation and rotation measurement

This study establishes Pd2ZrIn as a weakly coupled, dirty-limit, type-II superconductor with a fully gapped, nodeless s-wave order parameter and preserved time-reversal symmetry, based on comprehensive muon spin relaxation and rotation measurements alongside electrical and magnetic characterization.

Superconducting properties of the three-dimensional Hofstadter-Hubbard model below the critical flux for Weyl points

This paper investigates the superconducting properties of the three-dimensional Hofstadter-Hubbard model with attractive interactions, revealing a critical magnetic flux that separates two distinct regimes: one where superconductivity emerges only above a finite interaction threshold due to Weyl points, and another where it occurs for arbitrarily weak attraction with BCS-like scaling.

Josephson diode effect in multichannel Rashba nanowires: role of inter-subband coupling

This study demonstrates that inter-subband coupling in multichannel Rashba nanowire Josephson junctions qualitatively alters the topological phase diagram and significantly enhances the Josephson diode effect, enabling nonreciprocal supercurrents even under Zeeman fields aligned with the spin-orbit direction—a mechanism absent in single-channel systems.

Competing Constraints on Superconductivity in Thick FeSe films

By combining high-throughput combinatorial synthesis with interpretable machine learning, this study reveals that optimizing superconductivity in thick FeSe films requires balancing competing constraints of c-axis expansion, stoichiometry, and disorder scattering, rather than simply maximizing compressive strain, to achieve a record onset transition temperature of 17.1 K.

Spatially-resolved voltage-reversal due to Bernoulli potentials in dissipative Bi2_2Sr2_2CaCu2_2O8+x_{8+x}

The study reports the observation of spatially-resolved, opposite-sign longitudinal voltage reversals along the edges of Bi2_2Sr2_2CaCu2_2O8+x_{8+x} Hall bar devices above the critical current, attributing this phenomenon to particle-hole symmetry breaking in moving vortices and the formation of opposing Bernoulli potentials driven by invasive voltage contacts.
