Scientific Achievement
By use of dynamical mean field theory (DMFT), we are able to demonstrate that 4f electrons are localized in infinite layer nickelates.
Significance and Impact
There has been much debate about the nature of 4f electrons in superconducting nickelates. We demonstrate that they play no role in the low energy physics.
Research Details
- Our DMFT calculations treat both nickel 3d and rare earth 4f orbitals as correlated orbitals.
- Hole doping is achieved by using supercells with partial replacement of praseodymium by strontium.
Argonne National Laboratory seeks solutions to pressing national problems in science and technology. The nation’s first national laboratory, Argonne conducts leading-edge basic and applied scientific research in virtually every scientific discipline. Argonne researchers work closely with researchers from hundreds of companies, universities, and federal, state and municipal agencies to help them solve their specific problems, advance America’s scientific leadership and prepare the nation for a better future. With employees from more than 60 nations, Argonne is managed by UChicago Argonne, LLC for the U.S. Department of Energy’s Office of Science.
The U.S. Department of Energy’s Office of Science is the single largest supporter of basic research in the physical sciences in the United States and is working to address some of the most pressing challenges of our time. For more information, visit https://energy.gov/science.
