“Electron transport in new conducting and superconducting systems” dedicated to the 70th Anniversary of Yu.A. Kolesnichenko

Recently, many new materials have appeared with non-trivial conductive properties, including: giant magnetoresistance, quantization of conductivity in nanoscale objects, existence of Dirac and Weyl fermions with high-mobility charge carriers, high-temperature and topological superconductivity, spin transport in compensated and uncompensated metals, quantum and spin Hall effects, appearance of Majorana-like states, strong change in conductivity as a result of the evolution of the band structure topology under the influence of external factors. Most often, such phenomena are observed in low-dimensional 2D and 1D systems as well as in strongly correlated and anisotropic conducting systems. In the near future, such materials are expected to be widely used as elements of modern nanoelectronics and spintronics, and also to create qubits in quantum computers. The reasons for the appearance of the above phenomena are still not fully understood and require both the development of new materials, the accumulation of experimental data, and the construction of new theories explaining these phenomena.

In this Special Issue, it is planned to present the results of the latest experimental and theoretical studies of new low-dimensional, as well as strongly correlated and anisotropic conductive materials, which can help both in explaining existing phenomena and in identifying fundamentally new physical concepts and obtaining new information about processes in these classes of conducting systems.
