WSi weak link element with a non-sinusoidal current-phase relation

This paper demonstrates that a tungsten silicide constriction embedded in a 3D RF-SQUID exhibits strong nonlinearity consistent with a sawtooth-like current-phase relation or quantum phase slip behavior, enabling the measurement of relaxation times for metastable persistent-current states.

Hubbard-UU-corrected electron-phonon interactions in strongly correlated materials via the finite-displacement method

This paper presents a finite-displacement algorithm that integrates Hubbard UU corrections into electron-phonon calculations for strongly correlated materials, demonstrating that these corrections significantly alter phonon stability and electron-phonon coupling in LaNiO2_2 and RuO2_2 by modifying Fermi surface topology, thereby resolving discrepancies between theoretical predictions and experimental observations.

Quantum-Critical, Spin-Fluctuation-driven Residual Resistivity and Emergent Universal Correlations in the Fermi-Liquid Regime of Heavy-Fermion Superconductors

This paper identifies and theoretically explains three robust empirical correlations linking residual resistivity, Fermi-liquid scattering, and superconducting transition temperature in heavy-fermion systems, demonstrating that quantum-critical spin fluctuations drive both inelastic scattering and an effective elastic channel that governs unconventional transport and pairing.

Incommensurability-Induced Enhancement of Superconductivity in One Dimensional Critical Systems

This paper demonstrates that incommensurate quasiperiodic modulations in one-dimensional critical systems significantly enhance superconductivity by inducing an algebraic scaling of the critical temperature with interaction strength, leading to a substantial increase in both the critical temperature and order parameter compared to uniform or commensurate systems.

Three-dimensional quantum Griffiths singularity in bulk iron-pnictide superconductors

This study reports the first observation of robust three-dimensional quantum Griffiths singularity in the superconductor-metal transition of bulk CaFe1-xNixAsF high-temperature superconductors, establishing a comprehensive quantum phase diagram that confirms the universality of this phenomenon in 3D unconventional superconducting systems.

Imaging stripe dynamics in trilayer nickelate La4_4Ni3_3O10_{10}

Using spin-polarized scanning tunneling microscopy, researchers visualized the local magnetic and charge distribution of stripe order in the trilayer nickelate La4_4Ni3_3O10_{10}, revealing a cuprate-like four-unit-cell periodicity, a significant energy gap, and the ability to trigger and image atomic-scale stripe dynamics via tunneling electrons.

Hidden weak-pairing superconductivity of non-interacting anyons obeying 13\frac{1}{3} statistics

This paper proposes that non-interacting charge-e/3e/3 anyons with θ=−π/3\theta=-\pi/3 statistics in fractional Chern insulators form a hidden weak-pairing ff-wave superconductor via a flux-attachment mechanism, where statistical gauge fluctuations drive composite fermions into a $p+ip$ paired state that resolves previous theoretical discrepancies with recent numerical and experimental observations.

Nearly perfect Fermi surface nesting in hole-doped La3_3Ni2_2O7_7 enables bulk superconductivity without pressure or strain

This study predicts that hole-doping La3_3Ni2_2O7_7 to a concentration of x≈0.4x \approx 0.4 induces nearly perfect Fermi surface nesting, which strongly enhances antiferromagnetic spin fluctuations to enable bulk superconductivity at ambient pressure without the need for external pressure or strain.

Quantum effective action for dissipative semiclassical dynamics

This paper utilizes the Schwinger-Keldysh formalism to derive quantum corrections to semiclassical Langevin dynamics for dissipative systems, demonstrating that these corrections are governed by zero-point energy in the low-temperature, weak-damping regime and applying the results to Josephson and bosonic junctions where they reach significant percent-level magnitudes.
