SCHEDULE: NOV 12-18, 2011

When viewing the Technical Program schedule, on the far righthand side is a column labeled "PLANNER." Use this planner to build your own schedule. Once you select an event and want to add it to your personal schedule, just click on the calendar icon of your choice (outlook calendar, ical calendar or google calendar) and that event will be stored there. As you select events in this manner, you will have your own schedule to guide you through the week.

You can also create your personal schedule on the SC11 app (Boopsie) on your smartphone. Simply select a session you want to attend and "add" it to your plan. Continue in this manner until you have created your own personal schedule. All your events will appear under "My Event Planner" on your smartphone.

DCA++ Study on Strong Correlated Electron System Case study: Nematic physics in Cuprate

SESSION: Research Poster Reception

EVENT TYPE: ACM Student Research Competition Poster, Poster, Electronic Poster

TIME: 5:15PM - 7:00PM

SESSION CHAIR: Bernd Mohr

ROOM:WSCC North Galleria 2nd/3rd Floors

ABSTRACT:
The DCA++ code implements a dynamic cluster quantum Monte Carlo (QMC) algorithm for the study of low-energy effective models of strongly correlated electron systems. It is written using a generic programming model and a Don't Repeat Yourself (DRY) philosophy and provides rich functionalities including flexible support for crystal structures, hybrid precision simulations as well as different QMC cluster solver algorithms. The DCA++ code provides a state-of-the-art tool to model and understand the physics of materials at the forefront of science. Here we describe an application to the cuprate high-temperature superconductors, which aims at unravelling the physics behind an electronic nematic phase, the spontaneous breaking of the rotational symmetry of the crystal, which has been observed in a number of experiments on these and related compounds.
