Parallel BiLSTM-Transformer networks for forecasting chaotic dynamics
Junwen Ma, Mingyu Ge, Yisen Wang +2
The nonlinear nature of chaotic systems results in extreme sensitivity to initial conditions and highly intricate dynamical behaviors, posing fundamental challenges for accurately…
Impact of on-site potentials on -breathers in nonlinear chains
Lin Deng, Chengguan Fang, Hang Yu +5
On-site potentials are ubiquitous in physical systems and strongly influence their heat transport and energy localization. These potentials will inevitably affect the dynamical pro…
The Structure of the Route to the Period-three Orbit in the Collatz Map
Weicheng Fu, Yisen Wang
This study analyzes the Collatz map through nonlinear dynamics. By embedding integers in Sharkovsky's ordering, we show that odd initial values suffice for full dynamical character…
-Breathers in the diatomic -Fermi-Pasta-Ulam- Tsingou chains
Lin Deng, Hang Yu, Zhigang Zhu +3
-Breathers (QBs) represent a quintessential phenomenon of energy localization, manifesting as stable periodic orbits exponentially localized in normal mode space. Their existenc…
