Purdue contributes to experiments on light-matter interactions for potential quantum technology applications
Purdue researchers collaborated in a Rice University-led study detecting a quantum shift that results from the strong coupling of light and an ultra-high mobility two-dimensional electron gas rotating in opposite directions.
The work, published on April 16 in Nature Photonics, describes a system predicted to go into a new ground state (or state of lowest energy) that physicists could use to study phase transitions and possibly harness for the development of quantum bits for advanced computing. Researchers found that inducing strong coupling of light and matter in the form of a two-dimensional electron gas leads to a quantum interaction of counter-rotating fields called the Bloch-Siegert shift.
