Riassunto

The book represents quantum rings as special class of modern high-tech materials structures at the nanoscale. It deals, in particular, with their formation by molecular beam epitaxy and droplet epitaxy of semiconductors, their topology-driven electronic, optical and magnetic properties. Highly complex theoretical models are developed to adequately explain the specific features of quantum rings. The results presented in the  book serve to develop low-cost high-performance electronic, spintronic, magnetic, optoelectronic and information processing devices based on various doubly-connected structures.

The third edition contains new chapters and significantly updated and extended chapters from the second edition. It provides an ample presentation of the recent advancements in the physics of quantum rings related to spin dynamics and the spin-orbit interaction (spin interference in Rashba rings, tunable exciton topology on type II InAs/GaAsSb quantum nanostructures), the electron-phonon interaction in ring-like structures, quantum-interference manifestations in novel materials (e.g., graphene cylinders, cyclocarbons, MoS₂), effects of electric field and THz radiation on optical properties of quantum rings and quantum-ring molecules. Special emphasis is made on fascinating novel effects emerging due to double-connectedness in various physical systems, ranging from the occurrence of the continuous geometric phase provoking formation of non-integer mode numbers in Möbius microring light cavities—through the inverse Faraday effect on the generation of current states in an array of superconductor nanorings—to the emergence of lightning-like magnetic flux bursts  into a macroscopic superconductor ring.

The new edition gives insight into the properties of various novel architectures, including coupled semiconductor quantum ring-quantum dot chains and concentric quantum rings, In(AsSbP) graded-composition quantum rings, topologic states of light in self-assembled and direct-printed ring-like cavities, optical and plasmon modes in Möbius-band-shaped resonators, the ferromagnetic resonance in various magnetic elements ranging from arrays of magnetic nanorings to individual 3D nanovolcanoes. It includes novel theoretical solutions to long-standing problems in the physics of quantum rings: interpretation of the observed magnetoresistance oscillations by a transmission model for superconductor quantum rings and adaptation of the Bardeen-Cooper-Schrieffer theory of superconductivity for metallic quantum rings with due account for the effects of double-connectedness on the electron properties.

Informazioni sull'autore

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.
