With the increase in installed capacity of wind turbines, stable operation power system has been affected. Accurate prediction is an important condition to ensure healthy development industry and safe grid. This paper first introduces current status methods under normal weather, them detail from three aspects: physical model method, statistical method combined method. Then, perspectives numerical simulation analysis methods, icy conditions introduced, problems faced by existing are pointed...
Abstract Quantum state purification is crucial in quantum communication and computation, aiming to recover a purified from multiple copies of an unknown noisy state. This work introduces general framework designed achieve the highest fidelity with specified probability characterize associated trade-offs. For i.i.d. states under depolarizing noise, our can replicate protocol proposed by [Barenco et al., SIAM Journal on Computing, 26(5), 1997] further provide exact formulas for explicit We...
The topological nature of electronic states in HoSb significantly depends on spin orderings (NM, AFM or FM configuration). Only the band structure HoSb's antiferromagnetic state is confirmed to be topologically nontrivial.
Novel compounds with two-dimensional square lattices formed by group IV or V elements (Si, Sn, Ge, Bi, and Sb) have been attracting a great deal of attention in recent times, mainly because the possible emergence various topological phases therein. Here, we successfully grow single crystals Sn-square-net based material $\mathrm{Sc}{\mathrm{Sn}}_{2}$, systematically perform their magnetization magnetotransport measurements. Clear quantum oscillations emerge isotherms along different field...
Nonsymmorphic compounds have attracted much interest owing to their potential nontrivial electronic states. Here, we grew V1−δSb2 single crystal with a nonsymmorphic space group I4/mcm and studied de Haas–van Alphen oscillations. Orientation-dependent magnetization showed quantum oscillations, allowing determination of the three-dimensional Fermi surface Berry phase. Our theoretical calculation implied that VSb2's band structures manifest flat bands along Γ–X path, Dirac crossings near P N...
The AuCu3-type intermetallic compounds ReIn3 (Re = a rare earth ion) with type-IV magnetic space groups are predicted to show topologically nontrivial electronic states. Here, we grow ErIn3 single crystals, and study their properties critical behaviors by means of the susceptibility, magnetization isotherm measurements. Combining detailed analysis susceptibility isothermal magnetization, find that this compound harbors complicated phase diagram, its moment arrangement appears not simply...
PrBi, a sister member of rare-earth monopnictide family, can serve as an excellent candidate to study the extreme magnetoresistance and nontrivial topological electronic states. In this paper, we perform angular measurements, bulk surface band structure calculations on compound. PrBi's is revealed be significantly angle-dependent, show fourfold symmetry always observed in nonmagnetic isostructural counterparts, including LaSb, LaBi, LuBi, so on. Its well reproduced by semiclassical two-band...
Non-Abelian geometry phase has attracted significant attention for the robust holonomic unitary behavior exhibited, which arises from degenerate subspace evolving along a trajectory in Hilbert space. It been regarded as promising approach implementing topologically protected quantum computation and logic manipulation. However, due to challenges associated with high-dimensional parameters manipulation, this matrix-valued not realized on silicon integrated photonic platform, is CMOS compatible...

Magnetic topological semimetals, a novel state of quantum matter with nontrivial band topology, have emerged as new frontier in physics and materials science. An external stimulus like temperature or magnetic field could be expected to alter their spin states thus the Fermi surface anisotropies features. Here, we perform angular magnetoresistance measurements electronic structure calculations reveal evolution HoSb's nature different states. The results manifest that its anisotropy is robust...
