Below are the most recent papers in this dynamic area of condensed matter physics, ready for you to explore.
This study demonstrates that individual Pd-octaethylporphyrin molecules decoupled from silver surfaces via a NaCl layer exhibit visible-wavelength up-conversion electroluminescence from their singlet state, a process mediated by a triplet relay state that stores energy between tunneling electrons.
This paper proposes a scalable silicon quantum computing architecture based on two-dimensional arrays of phosphorus-donor clusters sharing bound electrons, which overcomes frequency crowding and placement challenges through natural hyperfine addressability and tunable exchange interactions to achieve high-fidelity, low-crosstalk operations compatible with fault-tolerant error correction.
This paper theoretically demonstrates that Coulomb interactions in a chain of ballistic metallic dots with frozen charge dynamics generate a unique neutral transport mode that violates the Wiedemann-Franz law, causing the Lorenz ratio to scale with the square root of the chain's length.
This study demonstrates that selectively displacing native wrinkles in stacked graphene induces a reversible transition to square moire superlattices, enabling the realization of highly correlated electronic states through the novel "twistraintronics" approach.
This study demonstrates that Coulomb interactions in normal-superconducting quantum-dot systems significantly degrade current precision and suppress violations of quantum uncertainty bounds by renormalizing resonant conditions and suppressing superconducting coherence, even when average currents remain largely unaffected.
This paper demonstrates the experimental realization and theoretical modeling of tunable topological phonon molecules and extended chains in GaAs/AlAs superlattices, where coupled interface states form hybridized modes and narrow minibands protected by the underlying band topology.
This paper presents a direct-write, low-cost electrochemical AFM lithography method using AC bias to fabricate sub-10 nm graphene nanoribbon field-effect transistors with high precision and low defect density, offering a superior alternative to conventional lithographic techniques for next-generation nanoelectronics.
This paper predicts that altermagnetic tunnel junctions utilizing the orbital-ordered material KV2Se2O exhibit large low-bias negative differential resistance and ultra-high tunneling magnetoresistance with sign inversion, driven by the material's unique quasi-2D Fermi surface under finite bias.
This paper theoretically and experimentally demonstrates that a finite quasiperiodic Fibonacci-type photonic chain can achieve robust, end-to-end topological pumping of light between non-neighboring elements, even in the presence of structural defects.
This paper demonstrates that constructing a type-I MoSe/PdSe van der Waals heterostructure enhances room-temperature A-exciton emission by approximately sixfold through interlayer electronic coupling that redirects exciton populations toward radiative channels, achieving a 6% quantum yield without chemical modification or strain.
