Superheating field of clean superconductors near the type-I--type-II boundary: the low-temperature Meissner stability limit of niobium

Using self-consistent nonlinear nonlocal Eilenberger theory, this paper calculates that the low-temperature superheating field of clean niobium near the type-I–type-II boundary is significantly higher than Ginzburg–Landau extrapolations, yielding an intrinsic Meissner-stability limit of approximately 67 MV/m for TESLA-shaped accelerator cavities.

Dichotomous electronic system in a bilayer Ni $^{1+}$ nickelate

The paper reports that the newly discovered bilayer nickelate La $_3$ Ni $_2$ O $_5$ F exhibits a unique dichotomous electronic system where a partially occupied interstitial-based electron band ( $E^*$ ) couples with Ni $d$ -orbitals to create a self-doped, two-dimensional structure that likely drives unconventional superconductivity.

On pseudogap phase as precursor to a superconducting dome in high-Tc cuprates: Non-analytic T* as a function of doping

This paper proposes that the superconducting dome in high-Tc cuprates emerges as a precursor to the pseudogap phase through a novel entanglement and confinement hole pairing (ECHP) mechanism, which dictates a non-analytic pseudogap temperature $T^*$ by balancing a decreasing pairing size with an increasing rate of configurational ordering as doping increases.

DC-operated Josephson junction arrays as a cryogenic on-chip microwave measurement platform

This paper demonstrates that DC-biased Josephson junction arrays can serve as both on-chip microwave sources and detectors in the C-band and beyond, offering a viable, fully DC-operated alternative to bulky room-temperature RF cabling for cryogenic quantum applications.

Percolative Pathway to Stripe Order in KTaO3-Based Superconductivity

This study demonstrates that controlled interfacial disorder in MgO/KTaO3(111) heterostructures drives a percolative transition from localized Cooper pairs to stripe-ordered superconductivity, revealing a self-organized modulation governed by spin-orbit coupling and lattice symmetry breaking.

Floquet Entanglement Generation in Parametrically Driven Coupled Superconducting Qubits

This paper investigates the dynamical generation of entanglement in parametrically driven coupled superconducting qubits, revealing a nontrivial mechanism driven by multiphoton resonance and Floquet state hybridization that enables efficient control of entanglement, including its complete suppression via coherent destruction.

Phase Formation and Thermal Stability of Superconducting Platinum Silicide Thin Films on Silicon

This study demonstrates that phase-pure, superconducting platinum silicide (PtSi) thin films with stable microstructures and consistent properties can be rapidly formed on silicon via thermal processing at 600°C, establishing a robust fabrication window for CMOS-compatible quantum devices while identifying interfacial roughening as an intrinsic consequence of the phase conversion rather than thermal degradation.

Microscopic mechanism of high-temperature superconductivity revealed by ab initio studies on hole-doped multilayer cuprates HgBa $_2$ Ca $_2$ Cu $_3$ O $_8$ under pressure

This study employs *ab initio* calculations with a neural network variational solver to reveal that the high-temperature superconductivity in pressurized HgBa $_2$ Ca $_2$ Cu $_3$ O $_8$ arises from an emergent local attraction generated by reduced offsite Coulomb repulsion and the release of "false vacuum" fluctuations, offering a new microscopic mechanism for designing optimized superconductors.

First-Principles Investigation of Electron--Phonon Coupling and Intrinsic Two-Gap Superconductivity in Hexagonal BAs3 Monolayer

This first-principles study predicts that a dynamically stable hexagonal BAs $_3$ monolayer is an intrinsic anisotropic two-gap superconductor with a critical temperature of 3.4 K, driven by sheet-dependent electron-phonon coupling primarily from low-frequency As-derived phonon modes.

Coexistence of High Temperature Superconductivity and Antiferromagnetic Order in a Cuprate with Multiple Hole Fermi Pockets

Using high-resolution laser-based ARPES, researchers discovered that the seven-layer cuprate Bi2267 exhibits high-temperature superconductivity ( $T_c \approx 75$ K) coexisting with strong antiferromagnetic order and multiple hole Fermi pockets, challenging conventional views on the roles of nodal and antinodal states in electron pairing.
