This study predicts that chiral single-walled carbon nanotubes undergo thermally induced rigid-body rotation via the Einstein-de Haas effect, driven by finite phonon angular momentum arising from the splitting of degenerate transverse acoustic and optical modes in small-diameter, intermediate-chiral-angle nanotubes.
This paper theoretically demonstrates a method for electrically reading out entangled molecular spin qubits by driving unpolarized currents through them, revealing that conductance is higher for singlet states than triplet states, particularly when utilizing materials with near-flat electronic bands.
This paper derives a quantum master equation to quantify phonon decoherence caused by two-level tunneling states in crystalline resonators, demonstrating that coherence times can be maximized at low temperatures and enhanced by positioning strain nodes at surface interfaces.
This study demonstrates that precise control of film thickness in GdFe single layers enables the engineering of room-temperature ferrimagnetic skyrmions with tunable size and density, evidenced by correlated magnetic force microscopy and topological Hall resistivity measurements, thereby establishing a viable pathway for high-density skyrmionic devices.
This paper predicts a novel class of robust, room-temperature geometric oscillations in the local Hall and Nernst coefficients of ballistic graphene rings, arising from discrete skipping orbits that connect measurement probes and offering potential applications in terahertz detection and thermal management.
This study optimizes room-temperature ozone sensors by demonstrating that Mn doping and specific halide compositions (Br-rich for p-type, Cl-based for n-type) significantly enhance sensitivity and stability, while clarifying the underlying gas interaction mechanisms through combined experimental and atomistic simulation approaches.
Using the auxiliary master equation approach, this study demonstrates that while moderate charge dephasing preserves the Kondo steady state in an interacting monitored quantum dot, spin dephasing destroys it through heating effects, ultimately revealing universal scaling of non-linear conductance governed by a dephasing-dependent Kondo scale.
This paper introduces a fluctuating Darcy model to demonstrate that space- and time-dependent porosity fluctuations significantly enhance or modify the hydrodynamic permeability of porous membranes compared to static matrices, offering new insights for optimizing membrane design.
This paper derives a generalized analytical expression for the Casimir-Polder interaction energy between a unipolarizable atom and a dielectric ring at any position, utilizing a novel class of integrals involving Jacobian elliptic functions to enable the investigation of atomic instability at off-axis equilibrium points.
This paper develops an effective low-energy theory demonstrating that smoothly varying altermagnetic spin textures generate unique emergent electromagnetic fields and quantum-geometric effects, such as spin-dependent electron lensing and local spin manipulation, which distinguish altermagnets from conventional magnetic systems and offer new avenues for spintronic applications.
