Double Quantum Dots Control Kondo Effect: "The Kondo effect occurs when electrons become trapped around the magnetic impurities in semiconductor materials, which prompts the electrons to change their spin. This phenomenon has intrigued scientists, as electronic correlations can create interesting and complex behavior in materials.

SystemsIn the new work, scientists demonstrate how the two quantum dot system can behave in two different and interesting ways: As a simile for a Kondo-effect system where one quantum dot is used to 'filter' the effect of the current leads, and as a way to study 'pseudo-gapped' systems and correlations in them, which can help scientists understand structures such as superconductors.
