Metal atoms and small clusters introduced into superfluid helium (He II) concentrate there in quantized vortices to form (by further coagulation) the thin nanowires. The nanowires’ thickness and structure are well predicted ...

A phenomenological derivation in the frame of London's and Ginzburg-Landau theories is given that photons behave inside a superconductor as if they have mass.

Recently, ionic liquid gating has been used to modulate the charge carrier properties of metal oxides. The mechanism behind it, however, is still a matter of debate. In this paper, we report experiments on doped and undoped ...

Optical characteristics of a single nanoparticle, coupled to the one-dimensional quantum molecular aggregate is studied. Depending on the values of the coupling of the particle and its own frequency, with respect to the ...

The phenomenological model, using which we can in a relatively simple way calculate many magnetic, thermodynamic and dynamic characteristics of the spin chain material with the geometrical frustration of spin-spin couplings ...

We show that a carbon nanotube can serve as a functional electric weak link performing photo-spintronic transduction. A spin current, facilitated by strong spin-orbit interactions in the nanotube and not accompanied by a ...

Processes of excitation energy transport were investigated for EuPO₄ and EuP₃O₉ nanocrystals, in which Eu³⁺ ions form three- and one-dimensional subsystems, respectively. It was determined that for EuPO₄ nanocrystals ⁵D₀ ...

Quantum technologies went through an explosive development since the beginning of the century. The progress in the field of superconducting quantum structures was especially fast. As the result, the design and characterization ...

Band structure calculations relevant to bis-ethylenedithio-tetrathiafulvalene-based charge transfer salts containing tris(oxalato)metallate anions, with generic formula (BEDT-TTF)₄A[M(C₂O₄)₃]·Solv, where A is a monovalent ...

The possibility of using miniaturized low-power electric motors submerged in superfluid helium for organization of rotation inside a cryostat has been investigated. It has been revealed that many of commercial micromotors ...
