Hall magnetohydrodynamics (HMHD) extends ideal MHD by incorporating the Hall effect via the induction equation, making it more accurate for describing plasma behavior at length scales below the ion skin depth. Despite its importance, a comp...

Chaos is ubiquitous in high-dimensional neural dynamics. A strong chaotic fluctuation may be harmful to information processing. A traditional way to mitigate this issue is to introduce Hebbian plasticity, which can stabilize the dynamics. H...

In this work, we investigate a generalization of the separatrix map to higher dimensions, in particular, a three-dimensional (3D) symplectic map derived from the Arnold Hamiltonian, which involves a pendulum and a free rotator coupled throu...

This study explores the effects of introducing a symmetry-breaking disorder on the dynamics of a system invariant under particle permutation. The disorder forces quantum states, confined to the N+1-dimensional completely symmetric space to ...

Active polymers under specific boundary constraints are a central topic in both biophysics and polymer physics. In this work, we perform a comparative study of polar active polymers with one end fixed, highlighting how the choice of the fix...

We study long-term evolution of radiating quasi-Q-balls in 1+1 dimensional models without mass threshold. Two different models are considered, the model with a rational modification of the usual Q-ball sextic potential and the model of a Q-...

The modulation and control of oscillatory phenomena in complex systems are essential with implications across biological, physical, neural, and engineered systems. Beyond pairwise interactions, higher-order networks have emerged as a valid ...

Determining the local roughness exponent α_{l} in nonequilibrium surface growth is challenging when transient morphologies with long crossover times, such as those in Villain-Lai-Das Sarma (VLDS) models, obscure the asymptotic regime. It w...
Parametric instability in discrete models of spatiotemporally modulated materials [0.03%]

We investigate the phenomenon of parametric instability in discrete models of spatiotemporally modulated materials. These materials are celebrated in part because they exhibit nonreciprocal transmission characteristics. However, parametric ...
Nonlinear modes coupling and chiral nonequilibrium dynamics in bosonic magnetic ladder under a harmonic trap [0.03%]

The bosonic magnetic ladder, a universal and the simplest model to reproduce the coupled effects of orbital magnetic field and optical lattices, provides an ideal platform for studying spin-orbit coupling, quantum phase transition and chira...
