Physics of Quantum Rings

Vladimir M. Fomin is a Research Professor at the Institute for Emerging Electronic Technologies, part of the Leibniz Institute for Solid State and Materials Research (IFW) Dresden, and a Professor at the State University of Moldova. He is also an Honorary Member of the Academy of Sciences of Moldova and a member of various esteemed scientific organizations including APS, the German Physical Society, the European Physical Society, IEEE, and the  COST Action “Superconducting Nanodevices and Quantum Materials for Coherent Manipulation”.His research interests lie in nanophysics, covering topics such as the theory of 3D nanoarchitectures, topology- and geometry-driven effects in quantum rings, strain-induced self-rolled and direct-write micro- and nanoarchitectures, phase boundaries and vortex matter in micro- and nanoarchitectures and patterned superconductors. He has also made significant contributions to understanding the superconducting properties of metallic nanograins, phonons, vibrational excitations, and polaronic effects in multilayerstructures and superlattices, magnetopolarons and magneto-Raman scattering in monolayer Transition Metal Dichalcogenides. Additionally, his work extends to exploring topological states of light and spin-orbit coupling in microcavities,  optical properties of quantum dots, thermoelectric properties of semiconductor nanostructures, quantum transport in sub-0.1 µm semiconductor devices, propulsion mechanisms of catalytic tubular micromotors, and theory of self-propelled micromotors for cleaning polluted water.He serves as the Scientific Editor of the Encyclopedia of Condensed Matter Physics, 2nd Edition (Elsevier, 2024), further demonstrating his expertise and authority in the field.
