Simulation results computed on first generation of Iridis supercomputer contribute to superconductivty insights
1st August 2011
Results computed on Iridis 1 during 2000-2002 at Southampton University are featured on the front page of the international condensed matter and materials physics (CMMP11) conference. The CMMP11, with a wide range of symposia, reflects the breadth of condensed matter and materials physics, and attracts the highest quality invited and plenary talks.
This year, the central theme is the 100th anniversary of the discovery of superconductivity. Hans Fangohr's work which he carried out at the University of Southampton with co-authors at Cambridge and the Argonne Laboratories 10 years ago, investigates the dynamics of vortices in high temperature superconductors, and has been selected to feature as the conference logo to contribute to the celebration of the century of superconductivity research.
Figure: Pancake vortices in one layer of a layered high temperature superconductor are visualised as blue spheres. They repel each other and form a hexagonal lattice which is disturbed due to thermal fluctuations. The potential energy from interactions with pancakes in other layers is visualised through the green energy surface and stabilises the lattice.
