This paper demonstrates a contact-free, post-growth method for spectrally tuning InAs quantum dots embedded in InP nanowires by utilizing the photo-induced strain relaxation of an amorphous Sb2S3 shell, thereby enabling the creation of wavelength-matched emitters essential for scalable quantum-photonic technologies.
This paper demonstrates that epitaxial growth of hcp Co with its c-axis in the film plane enables reconfigurable, field-free spin Hall nano-oscillators operating above 10 GHz by utilizing crystallographic anisotropy to replace the need for an external magnetic bias.
This paper demonstrates that in the nonreciprocal Aubry-André-Harper model, nonreciprocity induces anomalous transport where the critical phase exhibits ballistic diffusion and energy-resolved dynamical quantum phase transitions, effectively reversing the transport hierarchy observed in Hermitian quasicrystals.
This study reports the observation of positive, quadratic-field magnetoresistance in high-mobility GaAs Corbino devices, demonstrating that hydrodynamic theories incorporating finite-slip boundary conditions can effectively model the crossover between diffusive and viscous electron flow regimes.
This paper proposes and analyzes a "symplectic Hopf insulator," a robust yet delicate topological phase in weakly interacting bosonic systems that realizes an integer-quantized Hopf invariant within the Bogoliubov-de Gennes framework, thereby extending topological classification beyond the standard tenfold way.
This study utilizes reactive molecular dynamics simulations to demonstrate that while amorphous carbon nanotubes and nanoscrolls exhibit lower critical fracture strains than their crystalline counterparts, their similar melting points and mechanical behaviors indicate that structural disorder overrides the topological differences that typically distinguish pristine nanotubes from nanoscrolls.
This molecular dynamics study reveals that the self-folding and self-scrolling behaviors of edge-deformed graphene sheets into graphene-based nanofolds or nanoscrolls are critically determined by the initial edge twist angles and temperature, with specific configurations leading to single-folded, multi-folded, or dual-state morphologies.
Molecular dynamics simulations reveal that while graphene and mixed graphene/graphane nanoribbons can dynamically form nanoscrolls around carbon nanotubes within specific temperature ranges, fully hydrogenated graphane nanoribbons only wrap the nanotube without scrolling.
The authors propose a universal mechanism for emergent inductance in ferromagnets driven by dynamical Aharonov-Casher phases arising from the interplay of spin-orbit coupling and magnetism, extending the concept beyond spiral textures to spatially-uniform systems for stable ultra-wideband spintronic applications.
This paper resolves the Dry Ten Martini Problem at criticality by proving that every allowed gap label of the almost Mathieu operator corresponds to an open gap for every irrational frequency, achieved through demonstrating the nondecreasing nature of the maximum Lyapunov exponent as coupling increases and utilizing a boundary balance argument to establish critical gap opening.
