Kac, M. “The Work of T.H. Reminiscence.” Physics Today 17, no. Statistical Mechanics II: Statistical Physics of Fields We continue the considerations of the first paper in this series by studying the time dependence of the spin-correlation functions in response to a step-function change in the external magnetic field. Did Maxwell discover the distribution of velocities in a gas during an exam set by Stokes? Nambu, Yôichirô. In a multiwire branch circuit, can the two hots be connected to the same phase? This explorable illustrates pattern formation and dynamics in the \(XY\)-model, an important model in statistical mechanics for studying phase-transitions and other phenomena.It's a generalization of the famous Ising-Model.The \(XY\)-model is actually quite simple.. Modify, remix, and reuse (just remember to cite OCW as the source. Initially all the dipoles are oriented randomly. >> Statistical mechanics of one-dimensional S=1/2 anisotropic XY model in transverse field with Dzyaloshinskii-Moriya interaction March 1994 Condensed Matter Physics We appreciate your continued effort and commitment to helping advance science, and allowing us to publish the best physics journals in the world. rev 2020.11.24.38066, The best answers are voted up and rise to the top, History of Science and Mathematics Stack Exchange works best with JavaScript enabled, Start here for a quick overview of the site, Detailed answers to any questions you might have, Discuss the workings and policies of this site, Learn more about Stack Overflow the company, Learn more about hiring developers or posting ads with us. Is this a correct rendering of some fourteenth-century Italian writing in modern orthography? ©2020 American Physical Society. The only references concerning the hamiltonian $H_N^{(\nu)}=-j \sum_{i,j} \boldsymbol{S}_i \cdot \boldsymbol{S}_j$, with $ \boldsymbol{S}_i=\left (S_i(1),\dots,S_i(\nu) \right)$ $\nu$-dimensional vectors, are a few papers by Stanley: Stanley, H. E. “Spherical Model as the Limit of Infinite Spin “A Lattice Model of Liquid Helium, I.” Progress of Theoretical Physics 16, no. Who was the first scientist to introduce it? Subscription History of XY model - Plane Rotator model, MAINTENANCE WARNING: Possible downtime early morning Dec 2/4/9 UTC (8:30PM…, “Question closed” notifications experiment results and graduation. doi:10.1143/PTP.16.569.

I would like to find out more about the history of the XY model. The $O(3)$-model, often called the Heisenberg model, was introduced much earlier, in the following paper: Finally, the general $O(N)$-models seem to have been introduced in. We don't offer credit or certification for using OCW. Physical Review A™ is a trademark of the American Physical Society, registered in the United States, Canada, European Union, and Japan.

This is one of over 2,200 courses on OCW. Dipole \(n\) then slowly aligns its orientation towards the average orientation of its neighbors. Design a web site that can be used to teach a topic related to Collective Behaviors to non-specialists. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. Physics As a model, you may wish to examine the following introduction to Bose–Einstein condensation. It should be formatted as a regular article with title, abstract, and bibliography. Using of the rocket propellant for engine cooling. In the model the orientation of a dipole \(n\) is quantified by and angle variable \(\theta _n \in [ 0, 2\pi ] \). doi:10.1103/PhysRev.176.718. The ideal project will involve a combination of literature review, discussion of an analytical or computational model, and application / analysis of experimental data.
