A symplectic dynamics approach to the spatial isosceles three-body problem

Xijun Hu, Lei Liu, Yuwei Ou +2

We study the spatial isosceles three-body problem from the perspective of Symplectic Dynamics. For certain choices of mass ratio, angular momentum, and energy, the dynamics on the…

Global Surfaces of Section and Periodic Orbits in The Spatial Isosceles Three Body Problem

Xijun Hu, Lei Liu, Yuwei Ou +1

We study the spatial isosceles three body problem, which is a system with two degrees of freedom after modulo the rotation symmetry. For certain choices of energy and angular momen…

Schottky-diode design for the world's leading telecommunication

Chi Ho Wong, Frank Leung Yuk Lam, Xijun Hu +1

The Schottky diode, BN/GaN layered composite contacting to bulk aluminum, is theoretically plausible to harvest wireless energy above X-band. According to our first principle calcu…

Mean index for non-periodic orbits in Hamiltonian systems

Xijun Hu, Li Wu

In this paper, we define mean index for non-periodic orbits in Hamiltonian systems and study its properties. In general, the mean index is an interval in R which is uniformly conti…

Morse index theorem for heteroclinic, homoclinic and halfclinic orbits of Lagrangian systems

Xijun Hu, Alessandro Portaluri, Li Wu +1

The purpose of this paper is to prove a new, more general version of the Morse index theorem for heteroclinic, homoclinic, and half-clinic solutions in general Lagrangian systems.…

An Index Theory for Collision, Parabolic and Hyperbolic Solutions of the Newtonian -body Problem

Xijun Hu, Yuwei Ou, Guowei Yu

In the Newtonian -body problem for solutions with arbitrary energy, which start and end either at a total collision or a parabolic/hyperbolic infinity, we prove some basic resul…
