Its key advantage is that, unlike with all other known highly accurate techniques, it is still possible to do the calculations for relatively large systems with many atoms \u00a0&#8211; providing you have a big enough computer (and QMC can exploit all the processors of even the largest parallel machine). Used in combination with other cheaper methods, it provides researchers with the final building block in an atomic scale micro-laboratory on their \u00a0computer which can be used to simulate small parts of the real world. Its practical application to real-life problems &#8211; via a general, widely-distributed computer program system &#8211; has been pioneered in the United Kingdom by members of our group, originally working together in Cambridge but now dispersed throughout the world. A number of our collaborators at various other universities &#8211; whose work is also discussed here &#8211; have also made fundamental contributions, both to our software, and to the field in general.<\/p>\n<p>This site exists for the following reasons:<\/p>\n<ul>\n<li>To tell you about the research of various groups in the U.K. QMC community. The site includes introductory and review information along with a library of as many of their relevant scientific articles as we can find (Click &#8216;Read&#8217;, &#8216;Community\u2192Projects&#8217; or &#8216;Community\u2192Blog&#8217;).<\/li>\n<li>It is the home of the quantum Monte Carlo computer program system &#8216;CASINO&#8217; . Here\u00a0 you can find all relevant information about this code,\u00a0 you can download it, and you can learn how to use it (click &#8216;CASINO&#8217;).<\/li>\n<li>It is the home page of that considerable proportion of the world&#8217;s QMC researchers who used to meet annually in Vallico Sotto, Tuscany, Italy at the <a title=\"Towler Institute\" href=\"http:\/\/www.vallico.net\/tti\/tti.html\">Apuan Alps Centre for Physics<\/a>, and it provides a library of slides from essentially all the talks ever given at those meetings. The site also provides information about the annual QMC summer schools run by the TCM group at the same venue (click &#8216;Events&#8217;).<\/li>\n<li>It attempts to provide a sense of community amongst QMC researchers; this is a participatory site where any approved user may contribute articles to at least the Blog and Projects section of this website (click &#8216;Community&#8217;). Active conversations also take place on the <a href=\"http:\/\/www.vallico.net\/casino-forum\">discussion forum<\/a> &#8211; in practice mainly concerning the use and abuse of CASINO &#8211; but any relevant topics are encouraged (Click &#8216;Discussion Forum&#8217;).<\/li>\n<li>It is the\u00a0 principal online resource for developers of the CASINO program (click &#8216;Software Development&#8217;).<\/li>\n<li>It provides access to tools and data vital to doing calculations, such as our library of pseudopotentials and corresponding Gaussian basis sets (click &#8216;Pseudopotentials&#8217;).<\/li>\n<\/ul>\n<p>We hope you enjoy using these resources!<\/p>\n<p>Mike Towler, Richard Needs, Neil Drummond, Pablo L\u00f3pez R\u00edos<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Quantum Monte Carlo (QMC)\u00a0 is an exciting, modern computational technique which allows us to approximately solve the equations of quantum mechanics &#8211; which are far too complicated to solve exactly &#8211; and in most cases get essentially the right answer.
