Burstiness and information spreading in the active particles systems
Wei Zhong, Youjin Deng, Daxing Xiong
We construct the temporal network using the two-dimensional active particle systems which are described by the Vicsek model. The bursts of the interevent times for a specific pair…
Unusual slow energy relaxation induced by mobile discrete breathers in one-dimensional lattices with next-nearest-neighbor coupling
Bin Xu, Jun Zhang, Wei Zhong +2
We study the energy relaxation process in one-dimensional (1D) lattices with next-nearest-neighbor (NNN) couplings. This relaxation is produced by adding damping (absorbing conditi…
A general improvement in the WENO-Z-type schemes
Ruo Li, Wei Zhong
A new type of finite volume WENO schemes for hyperbolic problems was devised in [36] by introducing the order-preserving (OP) criterion. In this continuing work, we extend the OP c…
Locally Order-Preserving Mapping for WENO Methods
Ruo Li, Wei Zhong
In our previous studies [17, 18], the commonly reported issue that most of the existing mapped WENO schemes suffer from either losing high resolutions or generating spurious oscill…
An extension of the order-preserving mapping to the WENO-Z-type schemes
Ruo Li, Wei Zhong
In our latest studies, by introducing the novel order-preserving (OP) criterion, we have successfully addressed the widely concerned issue of the previously published mapped weight…
Towards building the OP-Mapped WENO schemes: A general methodology
Ruo Li, Wei Zhong
A serious and ubiquitous issue in existing mapped WENO schemes is that most of them can hardly preserve high resolutions and in the meantime prevent spurious oscillations on solvin…
A new mapped WENO scheme using order-preserving mapping
Ruo Li, Wei Zhong
Existing mapped WENO schemes can hardly prevent spurious oscillations while preserving high resolutions at long output times. We reveal in this paper the essential reason for such…
An efficient mapped WENO scheme using approximate constant mapping
Ruo Li, Wei Zhong
We present a novel mapping approach for WENO schemes through the use of an approximate constant mapping function which is constructed by employing an approximation of the classic s…
A modified adaptive improved mapped WENO method
Ruo Li, Wei Zhong
We propose a new family of mapped WENO schemes by using several adaptive control functions and a smoothing approximation of the signum function. The proposed schemes introduce the…
Approximate dynamical eigenmodes of the Ising model with local spin-exchange moves
W. Zhong, D. Panja, G. T. Barkema
We establish that the Fourier modes of the magnetization serve as the dynamical eigenmodes for the two-dimensional Ising model at the critical temperature with local spin-exchange…
