Predictive calculations of cuprate magnetic properties
June 24, 2014 — Magnetic couplings in a realistic cuprate system have been correctly predicted for the first time with highly accurate Quantum Monte Carlo (QMC) calculations. Effective magnetic models of superconductivity (previously reliant on experiment) can now be derived with confidence from theory, which could lead to better fundamental predictions of superconductor behavior.
Elementary excitations in liquids
May 15, 2013 — Elementary excitations in metallic liquids were discovered through computer simulation, representing a major advance in the physics of liquids. In solids the elementary excitations of lattice dynamics are phonons, but in liquids they have a very short lifetime.
