This paper proposes a general, symmetry-based real-space Hamiltonian framework that bridges the gap between global topological invariants and local far-field defects in photonic systems, enabling the intuitive design of structures with arbitrary topological properties across both localized and delocalized mode limits.
This paper demonstrates that thermally stable perpendicular magnetic tunnel junctions can be driven by nanosecond pulses to generate tunable random telegraph noise, establishing a versatile platform for integrating deterministic, stochastic, and in-memory functionalities in probabilistic and neuromorphic computing systems.
This paper reviews two magnetic tunnel junction (MTJ) approaches for high-speed, low-power true random number generation—passive-read superparamagnetic MTJs and stochastic-write MTJs—highlighting their distinct performance characteristics, integration benefits with advanced CMOS and STT-MRAM, and specific suitability for probabilistic computing versus edge cryptographic applications.
This paper investigates how steady-state drift currents in parallel graphene sheets, modeled via a shifted Fermi disk, induce a repulsive correction that reduces the overall attractive Casimir force and generates a lateral force opposing the carrier flow, offering new pathways for controlling Casimir interactions.
This paper establishes a unified theoretical framework explaining the microscopic origin of strain-induced photoluminescence in monolayer WS as a two-step conversion between hybridized -K excitons mediated by a previously unrecognized intermediate state, thereby predicting a novel, continuously tunable "sinusoidal" valley control mechanism for advanced valleytronic applications.
This paper extends analytical methods for strong-field effects in one-dimensional semiconductors from traditional Wannier excitons to the more localized Frenkel regime, deriving closed-form expressions for Stark shifts, ionization rates, electroabsorption spectra, and dynamic polarizability.
This paper demonstrates that injecting a spin current into a bismuth-substituted yttrium iron garnet thin film can dynamically stabilize an inverted magnetization state against external fields up to 3000 times the coercivity by exciting a population of incoherent magnons and antimagnons, thereby enabling new avenues for controlling magnetic states and studying relativistic analogs in solid-state systems.
This paper introduces an advanced electron backscatter diffraction (EBSD) reindexing technique that successfully maps local ferroelectric polarization directions in both single crystals and polycrystals by overcoming pseudosymmetry challenges through optimized pattern processing, neighbor averaging, and a novel confidence index.
