A Unified Frequency Domain Cross-Validatory Approach to HAC Standard Error Estimation

no code implementations13 Aug 2021 Zhihao Xu, Clifford M. Hurvich

Our candidate class consists of restricted maximum likelihood-based (REML) autoregressive spectral estimators and lag-weights estimators with the Parzen kernel.

Dynamical evolution in a one-dimensional incommensurate lattice with $\mathcal{PT}$ symmetry

no code implementations14 Jan 2021 Zhihao Xu, Shu Chen

We investigate the dynamical evolution of a parity-time ($\mathcal{PT}$) symmetric extension of the Aubry-Andr\'{e} (AA) model, which exhibits the coincidence of a localization-delocalization transition point with a $\mathcal{PT}$ symmetry breaking point.
