Insights into the quantum spintronic engine

Topic description

The quantum properties of atoms 1-dimensional (1D) spin chains are nowadays routinely tested using scanning tunneling microscopes2. Separately, intense research is focusing on how a quantum system can couple with the quantized levels of optical cavities3. To merge the physics of these research tracks onto an applicative path, our team has been studying the quantum properties of antiferromagnetic spin ½ 1D chains borne by molecules, when inserted into vertical spintronic nanopillar junctions4–6. Several published results, and preliminary measurements, depict how the quantum properties of the quantum entangled spin chain are profoundly altered due to fully spin-polarized charge transfer from the junction’s metallic interfaces, and the resulting spintronic cavity confinement. A number of spintronic mechanisms have been invoked to explain the very strong on-site spin splitting ~5-T of the potential qubit, and cyclical (i.e. engine), autonomous on-c...
