Enhanced superconductivity in palladium hydrides by non-perturbative electron-phonon effects

This paper demonstrates that accurately predicting the anomalous isotope effect and critical temperatures in palladium hydrides requires a non-perturbative framework that consistently treats anharmonic effects in both phonon spectra and electron-phonon interaction vertices, overcoming the limitations of previous methods that either neglected non-linear coupling or relied on flawed perturbative expansions.

Limited coincidence between ultrahigh-field superconductivity and line of metamagnetic endpoints in UTe2_2

This study reveals that in UTe2_2, the ultrahigh-field superconducting region coincides with the line of metamagnetic endpoints only within a narrow angular range near the $ab$ plane, while the two phase boundaries diverge as the magnetic field tilts toward the cc axis.

Dynamics of Charge-Density-Wave puddles in 2HH-NbSe2_2

This study reveals that the dynamics of charge-density-wave puddles in 2HH-NbSe2_2 give rise to a novel Fano-coupled phonon-CDW hybrid mode, characterized by a low-frequency overdamped oscillation that emerges below 17 K and highlights the critical role of lattice pinning and electronic correlations in stabilizing incommensurate CDW order.

Photonic heat transport through a Josephson junction in a resistive environment

Motivated by recent experiments, this paper derives general expressions for photonic heat transport through a Josephson junction in a dissipative environment, demonstrating that the heat current remains sensitive to Josephson coupling on the insulating side with opposite behaviors for series and parallel configurations, while also predicting heat rectification properties.

Unified mechanism of charge-density-wave and high-TcT_c superconductivity protected from oxygen vacancies in bilayer nickelates

This paper proposes a paramagnon-interference mechanism that explains the coexistence of charge- and spin-density waves in bilayer nickelates, demonstrating how their cooperative fluctuations drive robust high-TcT_c ss-wave superconductivity that is protected from oxygen vacancies.

Exact Duality at Low Energy in a Josephson Tunnel Junction Coupled to a Transmission Line

This paper theoretically demonstrates an exact duality mapping between the low-energy charge-dependent bands of a charge-biased Josephson tunnel junction coupled to a finite transmission line and its flux-biased counterpart, revealing that both systems converge to a resistively shunted junction in the infinite-length limit and highlighting the system's intrinsic self-duality and critical behavior.

Collective Modes in Weyl Superconductors and the Axial Anomaly

This paper develops a covariant Lagrangian framework for time-reversal symmetry-broken Weyl superconductors to demonstrate that FFLO pairing spontaneously breaks axial U(1)AU(1)_A symmetry, generating a pseudo-scalar Nambu-Goldstone mode that couples to gauge fields via the axial anomaly and predicts additional vector and axial-vector collective excitations analogous to mesonic modes in QCD.

Microscopic Phase-Transition Framework for Gate-Tunable Superconductivity in Monolayer WTe2_2

This paper develops a microscopic framework incorporating Nambu-Goldstone and Berezinskii-Kosterlitz-Thouless fluctuations to explain the anomalous gate-tunable superconductivity in monolayer WTe2_2, successfully reproducing key experimental observations such as the contrasting carrier-density dependence of TcT_c and the sudden disappearance of superconducting fluctuations under strong disorder.
