Numerical Methods for Antiferromagnets [PDF]
IEEE Transactions on Magnetics, 2020 Compared with ferromagnetic counterparts, antiferromagnetic materials are considered as the future of spintronic applications since these materials are robust against the magnetic perturbation, produce no stray field, and display ultrafast dynamics. There are (at least) two sets of magnetic moments in antiferromagnets (with magnetization of the same ...

Numerical Methods for Multilattices [PDF]
Multiscale Modeling & Simulation, 2012 Among the efficient numerical methods based on atomistic models, the quasicontinuum (QC) method has attracted growing interest in recent years. The QC method was first developed for crystalline materials with Bravais lattice and was later extended to multilattices (Tadmor et al, 1999).

Numerical methods for fractional diffusion [PDF]
Computing and Visualization in Science, 2018 We present three schemes for the numerical approximation of fractional diffusion, which build on different definitions of such a non-local process. The first method is a PDE approach that applies to the spectral definition and exploits the extension to one higher dimension.

ChatGPT FOR PROGRAMMING NUMERICAL METHODS
Journal of Machine Learning for Modeling and Computing, 2023 ChatGPT is a large language model recently released by the OpenAI company. In this technical report, we explore for the first time the capability of ChatGPT for programming numerical algorithms. Specifically, we examine the capability of GhatGPT for generating codes for numerical algorithms in different programming languages, for debugging and ...

Tbilisi Mathematical Journal, 2012 Numpy and SciPy are program libraries for the Python scripting language, which apply to a large spectrum of numerical and scientific computing tasks. The Sage project provides a multiplatform software environment which enables one to use, in a unified way, a large number of software components, including Numpy and Scipy, and which has Python as its ...

Bayesian Probabilistic Numerical Methods [PDF]
SIAM Review, 2019 The emergent field of probabilistic numerics has thus far lacked clear statistical principals. This paper establishes Bayesian probabilistic numerical methods as those which can be cast as solutions to certain inverse problems within the Bayesian framework.

A Numerical Study of the Probe Method
SIAM Journal on Scientific Computing, 2006 The goal of this work is the numerical realization of the probe method suggested by Ikehata for the detection of an obstacle D in inverse scattering. The main idea of the method is to use probes in the form of point source $\Phi(\cdot,z)$ with source point z to define an indicator function $\hat{I}(z)$ which can be reconstructed from Cauchy data or far

Numerical Optimization Methods in Economics [PDF]
, 2008 Optimization problems are ubiquitous in economics. Many of these problems are sufficiently complex that they cannot be solved analytically. Instead economists need to resort to numerical methods. This article presents the most commonly used methods for both unconstrained and constrained optimization problems in economics; it emphasizes the solid ...
