We discuss the properties of topologically nontrivial superconducting phases and the
conditions for their realization in condensed matter, the criteria for the appearance of …

The effective Hamiltonian for an electron in a quasi-one-dimensional quantum ring in the
presence of spin-orbit interactions is derived. We demonstrate that, when both coupling …

Owing to the nonlocal character of the Majorana state, the corresponding excitations are of
great interest. It is demonstrated that the direct consequence of such nonlocality is the …

Besides spin, the valley degree of freedom is also a promising candidate as a carrier of
information. Spintronics has come a long way, and spin modulation can be realized by …

Обсуждаются свойства сверхпроводящих фаз с нетривиальной топологией и условия
их реализации в конденсированных средах, критерии появления в твёрдых телах …

In electronic transport through mesoscopic systems, the various resonances in quantities
such as conductance and scattering cross sections are characterized by the universal Fano …

Proposal for construction of a source of spin-polarized current based on quantum point
contact (QPC) with local spin-orbit interaction is presented. We show that spin-orbit …

In an open quantum system having a channel in the form of loop geometry, the current
inside the channel, namely circular current, and overall junction current, namely transport …

We study transport properties of hexagonal zigzag graphene quantum rings connected to
semi-infinite nanoribbons. Open two-fold symmetric structures support localized states that …

Topological insulators exhibit gapless edge or surface states that are topologically protected
by time-reversal symmetry. However, several promising candidates for topologically …
