Project funded by Croatian Science Foundation (HRZZ) (Research Projects), grant IP-2016-06-2289. Participating organisations named by the source: Prirodoslovno-matematički fakultet, Zagreb; University of Zagreb, Faculty of Science. Funded amount: EUR 126,319, as stated by the source. Runs 2017-03-15 to 2022-03-14. Keywords: magnetic field, magnetic breakdown, synthetic gauge field, density wave, quantum oscillations, NEMS. Source: OpenAIRE Graph, from the funder's project data (collected by OpenAIRE on 2026-07-23); national funding data, not CORDIS; selected because its keywords name quantum. Abstract given by the source: The first goal of this project is to formulate a theoretical approach for researching new features under the influence of magnetic field and other calibration fields, induced by lattice deformation, on collective, structural, magnetotransport and electromechanical properties of reduced dimension materials, ie 2D and quasi-2D systems such as graphene. graphene-based compounds and some hi-Tc cuprates. We want to investigate the special role of magnetic penetration in graphene and similar systems in which the electron-electron interaction is not emphasized by the “nesting” of the Fermi surface. Also in special focus is the unique property of the graphene system with Dirac electron dispersion: the formation of strong pseudomagnetic fields due to the mechanical deformation of the lattice. Our preliminary estimates indicate the possibility of a new type of ground state — a magnetic wave-induced density wave due to a synthetic magnetic field that may explain the observed charge density wave in intercalated CaC6 graphite. We also want to investigate the occurrence of quantum oscillations in magnetotransport, fundamentally influenced by magnetic breakthrough, observed in graphene systems and hi-Tc cuprates. Furthermore, we will investigate a nanoelectromechanical system based on graphene and a spin-gate mechanism in order to find the parametric space for the formation of self-excited oscillations due to magnetomotor bonding of electronic and mechanical subsystems with special focus on the role of synthetic fields. The second goal is the experimental realization, ie the design and fabrication of a nanoscale device based on spin effects induced by a magnetic field. We will also explore new collective states by combining materials with different landscaping parameters or topologically protected states. In addition to fabrication, we will measure the complete magnetotransport characteristic.
