Phys.org May 31, 2022 Researchers in Japan mathematically modeled the electron scattering Kondo effect in ferrimagnetic substances. They used a novel T-shaped lattice of four quantum-dots connected to two reservoirs of electrons to induce a current. While pairs of quantum-dots have been used to model quantum phenomena before, the T-shaped arrangement was new and allowed ferrimagnetism to emerge. Due to the symmetrical geometric configuration of the system, they expected to go from the minimal ferrimagnetic state to the Kondo state without going through other quantum entangled states, amplifying the electrical conductivity as usual. But it was suppressed, contrary to their […]
