| Disorder by design in strongly correlated materials |
Abstract: Generally, uniformity in materials is seen as critical to phase order, with disorder and defects being thought to result in lower ordering temperatures and prevention of long-range percolation. However, disorder is an important aspect of many materials… Show more Speaker: Dr. Alessandro R. Mazza, Los Alamos National Laboratory |
