Scientific Achievement
Momentum conserved tunneling into a quantum Hall system reveals elementary excitations at its edge.
Significance and Impact
This work enhances our understanding of the basic elements of potential quantum computers.
Research Details
- Electrons at the quantum Hall edge are assumed to interact strongly with each other.
- The dependence of the tunneling strength on energy is evaluated exactly.
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.
