Researchers from the University of Illinois at Urbana-Champaign are using supercomputing resources at the Argonne Leadership Computing Facility (ALCF), a DOE Office of Science User Facility, to shed light on the mysterious nature of high-temperature superconductors.

As part of the project, the team used Mira, the ALCF's IBM Blue Gene/Q supercomputer, to carry out quantum Monte Carlo (QMC) simulations of the structure of electrons in iron selenide at an unprecedented level of detail.
