In the framework of this initiative we had several unexpected exceptional findings. Here, we briefly highlight two recently found phenomena. We identified a quantum form of electronic flicker noise that contains valuable information on quantum conductors. This noise is experimentally studied in atomic and molecular junctions, and theoretically analyzed considering quantum interference due to fluctuating scatterers. The identified form of flicker noise uniquely depends on the distribution of transmission channels, which are a central characteristic of quantum conductors. This dependence opens the door for the application of flicker noise as an accessible probe for fundamental properties of quantum conductors and many-body quantum effects (Phys. Rev. Lett. 2022). When the dimensions of materials are reduced to the nanoscale, magnetic properties can emerge as a result of structural changes. Recently, we found the inverse effect, where the size and direction of applied magnetic fields affect the structural properties of nanostructures. Specifically, we have found that parameters such as interatomic distance, formation probability, and the stability of metal and metal-oxide atomic wires can be tuned by magnetic fields, paving the way for magnetic control over material properties at the atomic scale (Nature Commun. 2022).
In view of the initial technological developments and scientific progress, we are now ready for the next phase of this initiative. In particular, we will finalize the analysis of our single molecule motor, mapping the parameters that control the operation of such a nanoscale motor. We intend to demonstrate magneto-thermoelectric effect in our chiral molecular junctions in order to achieve magnetic control over thermopower in nanoscale devices. In another project, electron vibration interaction will be used to gain heat pumping in molecular junctions, using a specially-made setup we have built. Finally, mechanical work to heat conversion - a process that is central for any mechanical device - will be characterized at the limit of miniaturization, in atomic scale junctions.
