Why is Boris algorithm so good

- H. Qin, S. Zhang, Jianyuan Xiao, Jian Liu, Y. Sun, W. M. Tang
- Physics
- 19 August 2013

Due to its excellent long term accuracy, the Boris algorithm is the de facto standard for advancing a charged particle. Despite its popularity, up to now there has been no convincing explanation why… Expand

Coherent coupling of two quantum dots embedded in an Aharonov-Bohm interferometer.

- A. Holleitner, C. Decker, H. Qin, K. K. Eberl, R. Blick
- Medicine, Physics
- Physical review letters
- 2 November 2000

We define two laterally gated small quantum dots with less than 15 electrons in an Aharonov-Bohm geometry in which the coupling between the two dots can be changed. We measure Aharonov-Bohm… Expand

Features and Mechanical Parameters of a Fabric's Compressional Property

- Mitsuo Matsudaira, H. Qin
- Materials Science
- 1995

The compressional and recovering curves of a fabric are considered to consist of three steps, respectively. The first and third steps of the compressional curve and the first step of the recovering… Expand

Automation of the guiding center expansion

- J. W. Burby, J. Squire, H. Qin
- Physics
- 11 July 2013

We report on the use of the recently developed Mathematica package VEST (Vector Einstein Summation Tools) to automatically derive the guiding center transformation. Our Mathematica code employs a… Expand

General gyrokinetic equations for edge plasmas

- H. Qin, R. H. Cohen, W. Nevins, X. Xu
- Physics
- 1 September 2006

During the pedestal cycle of H-mode edge plasmas in tokamak experiments, large-amplitude pedestal build-up and destruction coexist with small-amplitude drift wave turbulence. The pedestal dynamics… Expand

Hamiltonian time integrators for Vlasov-Maxwell equations

- Y. He, H. Qin, Y. Sun, Jianyuan Xiao, Ruili Zhang, J. Liu
- Physics
- 22 May 2015

Hamiltonian time integrators for the Vlasov-Maxwell equations are developed by a Hamiltonian splitting technique. The Hamiltonian functional is split into five parts, which produces five exactly… Expand

Energetically consistent collisional gyrokinetics

- J. W. Burby, A. Brizard, H. Qin
- Physics
- 24 March 2015

We present a formulation of collisional gyrokinetic theory with exact conservation laws for energy and canonical toroidal momentum. Collisions are accounted for by a nonlinear gyrokinetic Landau… Expand

Limit theory of bivariate dual generalized order statistics with random index

- M. A. Abd Elgawad, H. Barakat, H. Qin, T. Yan
- Mathematics
- 4 May 2017

ABSTRACT The class of limit distribution functions of bivariate extreme, intermediate and central dual generalized order statistics from independent and identically distributed random variables with… Expand

Noether Currents for Eulerian Variational Principles in Non Barotropic Magnetohydrodynamics and Topological Conservations Laws

- A. Yahalom, H. Qin
- Physics
- 26 May 2020

We derive a Noether current for the Eulerian variational principle of ideal non-barotropic magnetohydrodynamics (MHD). It was shown previously that ideal non-barotropic MHD is mathematically… Expand

Guiding-center Vlasov-Maxwell description of intense beam propagation through a periodic focusing field

- R. C. Davidson, H. Qin
- Physics
- 24 October 2001

This paper provides a systematic derivation of a guiding-center kinetic model that describes intense beam propagation through a periodic focusing lattice with axial periodicity length $S$, valid for… Expand
