Article Abstract

The anomalous chaotic transport in a one-degree-of-freedom Hamiltonian system subjected to a small time-periodic perturbation is investigated. Strong quasiperiodic dependencies of the statistical properties of the motion on log epsilon are found, where epsilon is a perturbation parameter. The period log lambda depends on the rescaling parameter lambda, which is determined only by the frequency of perturbation and behavior of unperturbed Hamiltonian near a saddle point. The results confirm and generalize a recently established new universal rescaling property of perturbed motion near a saddle point.

Model integration refers to the process of incorporating a fitted historical model into the estimation of a current study to increase statistical efficiency. Integration can be challenging when the current model includes new covariates, leading to potential model misspecification. We present and evaluate seven existing and novel model integration techniques, which employ both likelihood constraints and Bayesian informative priors.

Article Synopsis
  • The study reveals that laser-assisted dynamic interference in electron spectra can be experimentally observed using attosecond pulse trains, demonstrating fine interference patterns smaller than the energy of individual laser photons.
  • Theoretical simulations align with experimental findings, utilizing methods like the time-dependent Schrödinger equation and strong-field approximation to support the results.
  • Further analysis emphasizes the significance of phase variations in electron wave packets, showing that the manipulation of electron behavior in the continuum is achievable through advanced multicolor laser techniques controlled at attosecond timescales.

The energy cascade, i.e. the transfer of kinetic energy from large-scale to small-scale flow motions, has been the cornerstone of turbulence theories and models since the 1940s.

Unconventional superconductivity is known for its intertwining with other correlated states, making exploration of the intertwined orders important for understanding its pairing mechanism. In particular, spin and nematic orders are widely observed in iron-based superconductors; however, the presence of charge order is uncommon. Using scanning tunnelling microscopy, and through expanding the phase diagram of iron-arsenide superconductor BaKFeAs to the hole-doping regime beyond KFeAs by surface doping, we demonstrate the formation of a charge density wave (CDW) on the arsenide surface of heavily hole-doped BaKFeAs.
