This paper predicts the existence of previously unobserved Bloch-type and twisted-Néel-type photonic skyrmions in chiral multilayered structures by exploiting the quantum spin Hall effect of plasmonic optical vortices, thereby expanding the photonic skyrmion family and offering new degrees of freedom for chiral sensing and information technologies.
This study utilizes optical pump-terahertz probe spectroscopy to reveal that ultrafast photoconductivity in epitaxial graphene nanoribbons exhibits a non-monotonic fluence dependence driven by an interplay between negative-sign conductivity from secondary hot carriers at low fluences and positive-sign conductivity from excess carriers at high fluences, resulting in complex variations in mobility and plasmonic resonance.
This study demonstrates that resonant mid-IR pulses can suppress quantum fluctuations in to induce a metastable ferroelectric state, providing a first-principles explanation for light-driven control of quantum phase transitions in oxide perovskites.
This study employs machine-learned interatomic potentials to simulate Ruddlesden-Popper chalcogenides, revealing diverse new polymorphs, unique structural behaviors like negative thermal expansion and ascending symmetry breaking, and layer-dependent tilt patterns driven by the competition between octahedral rotations and interface rumpling.
Although YbCuSe lacks magnetic order, significant structural disorder prevents a quantum spin liquid ground state, leading instead to a universal 2D random singlet phase characterized by a distribution of singlet formations.
This study validates the accuracy of the UMA universal machine learning interatomic potential for 25 different MoS2 dopants and demonstrates its ability to efficiently simulate complex phenomena like dopant clustering and layer fracturing, thereby enabling high-throughput computational design of doped MoS2 for targeted applications.
This paper demonstrates a folded-bilayer graphene spin-valve device that achieves giant non-local spin signals in the millivolt range and pronounced spin-rectification effects, establishing a promising platform for active two-dimensional spintronic applications.
This study investigates the broadband terahertz conductivity and ultrafast photoconductivity of multilayer epitaxial graphene nanoribbons, revealing that near-field imaging detects nanoscale inhomogeneities while far-field spectroscopy distinguishes doped substrate layers from quasi-neutral layers that exhibit high mobility and strong positive photoconductivity driven by carrier temperature-dependent scattering mechanisms.
This paper presents a first-principles implementation of the DFT formalism within the all-electron FLAPW method using the FLEUR code, demonstrating improved accuracy for diverse materials ranging from covalent semiconductors to charge-transfer insulators by incorporating intersite Coulomb interactions derived via the constrained random-phase approximation.
This paper demonstrates a monolithic, two-step epitaxial growth method using buried stressors to fabricate precisely positioned, site-controlled InGaAs quantum dots with tunable local densities, enabling the integration of single-photon sources and microlasers on a single photonic chip for advanced quantum technologies.
