This study demonstrates that dipolar coupling between InP/ZnS quantum dots and carbon nanotubes in hybrid thin films creates a cross-dimensional excitonic platform where resonant Raman scattering reveals significant spectral shifts, intensity enhancements, and an effective splitting of approximately 110 meV that are not readily apparent in ensemble absorption spectra.
This study demonstrates single-shot laser-pulse-induced magnetization reversal in rare-earth-free CoFeB/MgO magnetic tunnel junctions by optimizing the Ru capping layer thickness, marking a significant step toward integrating ultrafast optical control with STT-MRAM technology.
This paper demonstrates that decorated Cayley trees, as tree analogs of specific two-dimensional lattices, exhibit flat energy bands that correspond to topological edge states of one-dimensional chains, revealing how non-Euclidean geometry alone can generate and stabilize unconventional quantum states.
This study investigates HgTe-based three-terminal Josephson junctions, revealing how the interplay between bias current and perpendicular magnetic fields enables tunable interference patterns, symmetry control, and strongly enhanced Josephson diode efficiency, with experimental findings quantitatively validated by resistively shunted junction simulations.
This study demonstrates that grain boundaries in free-standing nanocrystalline silicon membranes act as a frequency-dependent spectral filter that strongly suppresses high-order confined acoustic phonon modes through scattering rates scaling with , effectively distinguishing their behavior from that of crystalline silicon.
This study demonstrates that chlorine alloying in the van der Waals antiferromagnet CrSBr systematically localizes excitonic wavefunctions and tunes magneto-excitonic coupling, establishing compositional engineering as a viable strategy for controlling light-matter interactions in magnetic semiconductors.
This study uses non-equilibrium molecular dynamics to demonstrate that while rough, deformable contacts induce plug flow and cavitation in single-component water and hydrocarbon lubricants, an immiscible two-fluid mixture uniquely minimizes friction and material transfer while sustaining plug flow to lower velocities, despite occasionally forming transient wear particles.
This study identifies a Wigner crystal phase as the origin of highly insulating states in rhombohedral pentalayer graphene and demonstrates how this phase drives the emergence of competing magnetic-field-stabilized superconductivity and unconventional reentrant quantum Hall states.
This paper proposes a theoretically exact framework for describing two-level systems in the strong coupling regime and outlines a feasible experimental protocol using solid-state quantum dots to determine the previously unknown parameters governing this interaction.
This paper demonstrates that coupling conventional superconductors to spatially varying altermagnetic textures induces spin-triplet superconductivity and supercurrent-driven torques, particularly within domain walls, thereby revealing a pathway for local Cooper pair engineering and the detection of altermagnetic order.
