Numerical integration methods for the double-bracket flow
Journal of Computational and Applied Mathematics, 2004 This paper is concerned with the numerical solution of the so called double-bracket matrix differential equation \( Y'(t)= [ [ Y(t), N ],] Y(t)], Y(0)= Y_0\) where \(N\) and \(Y_0 \) are \( n \times n \) constant real matrices with \(Y_0\) symmetric, and \( [A,B]= A B-B A\). Since the author is interested in geometric integrators and this equation is a

Quantizing Dirac and Nambu Brackets
, 2003 AIP Conf.Proc.672:165-182,2003 We relate classical and quantum Dirac and Nambu brackets. At the classical level, we use the relations between the two brackets to gain some insight into the Jacobi identity for Dirac brackets, among other things.

Advanced Functional Materials, EarlyView.This work explores the possibility to design stable periodic magnetization textures by transforming a 2D film into a rolled‐up 3D architecture and back. In case of an isotropic exchange‐biased layer architecture, the magnetization encoded in the 3D state evolves into a spin‐spiral pattern with controlled periodicity after unrolling.

Global root bracketing method with adaptive mesh refinement [PDF]
Applied Mathematics and Computation, 2015 An efficient method for finding all real roots of a univariate function in a given bounded domain is formulated. The proposed method uses adaptive mesh refinement to locate bracketing intervals based on bisection criterion for root finding. Each bracketing interval encloses one root. An adaptive form of error is introduced to enclose roots in a desired
