Using low-temperature scanning tunneling microscopy, this study reveals that individual Sm adatoms on graphene/Ir(111) exhibit reversible variable charge states, distinct magnetic excitations confirming a Sm ground state with retained 4f filling, and a novel Kondo resonance with a large Zeeman splitting.
This paper presents a direct electrical detection method for spin chemical potential generated by the Spin Hall Effect in -Tungsten and Platinum using a ferromagnetic-normal metal voltage probe pair, which successfully validates the measurement scheme through reciprocity with the Inverse Spin Hall Effect and reveals a pronounced power-law dependence of spin Hall resistivity on material resistivity across a wide range.
This paper develops a theory demonstrating that microwave-driven superconducting qubits suffer from two specific quasiparticle-induced decoherence mechanisms involving photon-assisted tunneling and drive-induced pair creation, which fundamentally limit the fidelity of quantum operations even in gap-engineered devices designed to be insensitive to quasiparticles.
This paper proposes and numerically validates a magnetic field-free platform using skyrmion crystal-coupled planar Josephson junctions, which enables the generation, nontrivial fusion, and braiding of Majorana bound states—even at higher temperatures with -wave superconductors—thereby overcoming the directional constraints of traditional in-plane magnetic fields for topological quantum computation.
This paper presents a theoretical framework demonstrating that strong exciton-photon coupling can suppress polariton radiation through destructive interference, creating bound states in the continuum with infinitely long radiative lifetimes and offering new design principles for advanced polaritonic applications.
This paper demonstrates that fractional Chern insulators can emerge in topologically trivial moiré graphene bands due to inhomogeneous quantum geometry reshaping Coulomb interactions, proving that many-body topological order does not strictly require single-particle band topology.
This paper proposes that depositing a tunable graphene monolayer on a metallic substrate enables the dynamic inversion of dipole-dipole coupling between H-type and J-type molecular aggregates by varying the surface conductivity, offering a practical route to observe this phenomenon in real-time experiments.
This study demonstrates that the direction of the spin-orbit field serves as an efficient control knob for tuning Andreev reflection and nonlinear conductance in proximitized semiconductor nanowire junctions, particularly within the topologically trivial phase.
This paper presents a deterministic pick-and-place technique for the vertical-to-vertical transfer of nanowire quantum dots, enabling the integration of photonic structures that achieve high photon extraction efficiency, tunable emission, and high-quality single-photon characteristics for scalable quantum technologies.
This study systematically characterizes low-frequency charge noise in bilayer graphene quantum dots, demonstrating that their noise levels are comparable to established semiconductor platforms and showing no significant degradation from proximitized transition metal dichalcogenide layers, thereby validating bilayer graphene as a viable platform for coherent quantum information processing.
