Disorder Driven Anisotropic Nonlinear Hall Effect in the Kagome Metal YbCo6Ge6 at Room Temperature
Advanced Science, EarlyView.The intrinsic structural disorder and short‐range correlated motifs in the kagome metal YbCo6Ge6 constitute the primary mechanism for a robust and anisotropic nonlinear Hall effect (NLHE). This effect is sustained across a wide temperature range, achieving a nonlinear responsivity of up to ∼4.5 × 10−3 m/V at 70 K, higher than known disordered and ...

Dual‐Functional Terahertz Manipulation of EuBa2Cu3O7 Superconductors via Cooper Pair Dynamics
Advanced Science, EarlyView.We use a spintronic‐metasurface THz emitter to realize chiral THz generation. Using polarization‐tunable THz pulses, we investigate equilibrium and photoinduced THz responses in a 43 nm thick EuBa2Cu3O7 (EBCO) thin film. The EBCO film achieves 46.81 dB EMI shielding and 113% photoinduced THz modulation with 19.0 ps recovery, enabled by Cooper‐pair ...

IEEE Transactions on Applied Superconductivity, 2018 This paper proposes the concept of “fault current limitation coordination” in a future electric power grid with multiple superconducting fault current limiters (SFCL). Not only the fault current limitation of each SFCL on a transmission line, but also the transient stability of the grid with SFCLs should be taken into account, because the disturbance ...

International Journal of Advanced Research in Electrical, Electronics and Instrumentation Engineering, 2015 Different types of distributed generation (DG) sources could be connected to the main power grid in order to improve the reliability of the power system, in a smart grid. The association of ac and dc distribution grid are assigned for the efficient connection of renewable power resources.

Customized Itinerant Frequency Combs by Cascaded Nonlinear Effects
Advanced Science, EarlyView.A cascaded third‐order nonlinear system generates an itinerant frequency comb with the comb center frequency decoupled from the cavity resonance. This enables arbitrary spectral scaling, flexible spacing adjustments, and real‐time central‐frequency engineering, allowing comb splicing and subdivision. The resulting versatility and reconfigurability open

SPICE‐Compatible Compact Modeling of Cuprate‐Based Memristors Across a Wide Temperature Range
Advanced Electronic Materials, EarlyView.A physics‐guided compact model for YBCO memristors is introduced, incorporating carrier trapping, field‐induced detrapping, and a differential balance equation to describe their switching dynamics. The model is compared with experiments and implemented in LTspice, allowing realistic circuit‐level simulations.
