Offer DescriptionJob Offer: Controlling dynamics in mesoscopic strongly correlated systemsField: Solid State Physics, Ultrafast SpectroscopyPosition: PhD studentInstitution: Jožef Stefan Institute (JSI), Ljubljana, SloveniaDepartment: Department of Complex MatterStrongly-correlated materials, or the materials, in which Coulomb interaction between the electrons cannot be neglected, became of great importance for technology and basic science. They exhibit a rich variety of exciting properties, such as metal-insulator transitions, unconventional superconductivity, heavy fermions, and unique magnetic orders. Additionally, recently reported long-lived hidden phases, which are accessible only at highly non-equilibrium conditions, such as laser excitation or short electrical current pulse, offer new platforms for non-incremental improvement in the performance of modern electronics, logical gates and non-volatile memory devices. For example, the recently presented laboratory prototype of charge-configurational storage developed at IJS is at least three orders of magnitude faster than any other existing memory device. However, a precise understanding of the nature of the hidden phases, which are responsible for the device operation, is still missing.The research within the PhD program will aim at finding the key ingredients required for stabilizing hidden orders in correlated electronic crystals, controlling their characteristics in mesoscopic devices and engineering the material properties on demand. The work will include the development of a new experimental framework for studying and manipulating mesoscopic devices on an ultrafast time scale.References related to the research:[1] I.
