To further motivate and promote the research of numerical relativity, gravitational wave physics and relevant fields in China, we are going to organize a spring school on numerical relativity and grav...
Physical vs. numerical dispersion in nonhydrostatic ocean modeling
Dispersion Nonhydrostatic effects Internal waves Ocean modeling Grid resolution requirements Leptic ratio Lepticity
2015/6/30
Many large-scale simulations of internal waves are computed with ocean models solving the primitive (hydrostatic) equations. Under certain circumstances, however, internal waves can represent a dynami...
Asymptotic behaviour and numerical approximation of optimal eigenvalues of the Robin Laplacian
Robin Laplacian Eigenvalues Optimisation
2012/4/18
We consider the problem of minimising the $n^{th}-$eigenvalue of the Robin Laplacian in $\mathbb{R}^{N}$. Although for $n=1,2$ and a positive boundary parameter $\alpha$ it is known that the minimiser...

Abstract: In this paper we investigate anisotropic Union Jack lattice Ising model system in terms of the spontaneous magnetisation. Identification of disagreements in the theories published by Wu and ...
Numerical evidence against a conjecture on the cover time of planar graphs
Numerical evidence the cover times of planar graphs Statistical Mechanics
2011/7/28
Abstract: We investigate a conjecture on the cover times of planar graphs by means of large Monte Carlo simulations. The conjecture states that the cover time $\tau(G_{N})$ of a planar graph $G_{N}$ o...
Polarization effects in $\bar N+N\to π+\ell^++\ell^-$ reaction. General analysis and numerical estimations
$\bar N+N\to π+\ell^++\ell^-$ reaction General analysis numerical estimations
2011/1/6
A general formalism is developed to calculate the cross section and the polariza-tion observables for the reaction ¯N + N ! π + ℓ+ + ℓ−. The matrix element and the observables a...

Numerical treatment of long-range Coulomb potential Berggren bases
2011/1/7
The Schr¨odinger equation incorporating long-range Coulomb potential takes the form of a Fred-
holm equation whose kernel is singular on its diagonal when represented by a basis bearing a contin-uum ...
Numerical study of the phase transitions in the two-dimensional Z(5) vector model
Numerical study phase transitions two-dimensional Z(5) vector model
2011/1/14
We investigate the critical properties of the two-dimensional Z(5) vector model.For this purpose, we propose a new cluster algorithm, valid for Z(N) models with odd values of N. The two-dimensional Z(...
System Level Numerical Analysis of a Monte Carlo Simulation of the E. Coli Chemotaxis
Numerical Analysis Monte Carlo Simulation the E. Coli Chemotaxis
2010/11/16
Over the past few years it has been demonstrated that "coarse timesteppers" establish a link between traditional numerical analysis and microscopic/ stochastic simulation. The underlying assumption o...
Numerical detection of unstable periodic orbits in continuous-time dynamical systems with chaotic behaviors
Numerical detection unstable periodic orbits continuous-time dynamical systems chaotic behaviors
2009/11/3
An infinite number of unstable periodic orbits (UPOs) are embedded in a chaotic system which models some complex phenomenon. Several algorithms which extract UPOs numerically from continuous-time chao...
