This study establishes the first comprehensive electronic phase diagram for fluorine-doped PrFeAsO1-xFx across the full doping range, revealing a dome-shaped superconducting region with a record-high Tc of 52.3 K, structural lattice contraction, and evidence of strong fluctuations and multiband pairing.
This paper demonstrates that free and interacting many-body systems can be isospectral yet exhibit fundamentally distinct phase structures and operator complexity dynamics, linked by a nonlocal unitary transformation that maps local operators to extended many-body strings.
By measuring quantum oscillations in rhombohedral tetralayer graphene, researchers discovered that the normal state transitions from a simple quarter metal to a complex "multitone" phase incompatible with previously proposed models, thereby challenging existing assumptions about the material's potential as a chiral superconductor.
This paper demonstrates that widely available consumer AI tools can synthesize realistic experimental data for quantum electronic devices by leveraging basic physics equations and signal characteristics, while recommending the sharing of large volumes of primary data as a countermeasure to identify such undisclosed synthetic outputs.
This study provides long-sought evidence for a BCS-BEC crossover in a high-Tc cuprate superconductor by demonstrating the coexistence of small Fermi pockets and a large superconducting gap in clean inner CuO2 layers, revealing an abrupt emergence of this crossover regime with increasing carrier density that establishes a microscopic foundation for d-wave pairing in doped Mott insulators.
Researchers have demonstrated a polarity-controllable superconducting diode based on a non-equilibrium Josephson junction in 2M-WS that achieves a record-breaking 2.4 GHz flip-flop operation with a high diode efficiency of 67% and an on-off ratio exceeding 10, offering a promising platform for advanced superconducting logic and broadband telecommunications.
This paper proposes that particle-hole interference between quasiparticles scattered from a single impurity and reflected by a boundary in superconductors generates a robust "ghost" interference pattern, offering a parametrically stronger and more sensitive local probe of superconducting electronic order and Fermi-surface anisotropy via STM/STS measurements.
This study employs first-principles calculations to predict that the ternary superhard metals BCN and BCN exhibit promising ambient-pressure superconducting transition temperatures of approximately 40 K and 20 K, respectively, driven by their high Debye temperatures and comparable formation energies to known synthesized compounds.
This paper presents a theoretical framework demonstrating that hybrid Josephson junction arrays, known as Andreev crystals, exhibit directional conductance at high interface transparency under a constant phase bias, enabling the creation of a tunable, one-way signal filter.
This review paper explores the deep connections between electronic liquid crystal phases, multipole expansions, and altermagnetism through the lens of nonrelativistic spin-momentum locking, while systematically examining the resulting unconventional superconducting states, their interplay with altermagnetic order, and their potential for future quantum technologies.
