The elliptical invariant tori of nearly integrable Hamiltonian system through symplectic algorithms
Zaijiu Shang, Yang Xu
In this paper we apply symplectic algorithms to nearly integrable Hamiltonian system, and prove it can maintain lots of elliptic lower dimensional invariant tori. We are committed…
A KAM theorem of symplectic algorithms for nearly integrabel Hamiltonian systems
Zaijiu Shang, Yang Xu
In this paper we prove a KAM-like theorem of symplectic algorithms for nearly integrable Hamiltonian systems which generalises the result of \cite{r1} and \cite{r6} for the case of…
Pressure tuning of optical reflectivity in LuH2
Xuan Zhao, Pengfei Shan, Ningning Wang +3
Recently, the claim of room-temperature superconductivity in nitrogen-doped lutetium hydride at near-ambient conditions has attracted tremendous attention. Criticism of the work ri…
Analysis and experimental study on the Jumping Chain
Wenyu Wang, Wu-Long Xu, Yang Xu +1
A freely falling chain from a cup at certain height can jump. The process can be divided into two parts: a stable suspension and an accelerating procedure. Variational principle an…
