    Focused Crossed Andreev Reflection

    Full text link
    We consider non-local transport in a system with one superconducting and two normal metal terminals. Electron focusing by weak perpendicular magnetic fields is shown to tune the ratio between crossed Andreev reflection (CAR) and electron transfer (ET) in the non-local current response. Additionally, electron focusing facilitates non-local signals between normal metal contacts where the separation is as large as the mean free path rather than being limited by the coherence length of the superconductor. CAR and ET can be selectively enhanced by modulating the magnetic field

    Loss of Andreev Backscattering in Superconducting Quantum Point Contacts

    We study effects of magnetic field on the energy spectrum in a superconducting quantum point contact. The supercurrent induced by the magnetic field leads to intermode transitions between the electron waves that pass and do not pass through the constriction. The latter experience normal reflections which couple the states with opposite momenta inside the quantum channel and create a minigap in the energy spectrum that depends on the magnetic field

    Tunable space-time crystal in room-temperature magnetodielectrics

    We report the experimental realization of a space-time crystal with tunable periodicity in time and space in the magnon Bose-Einstein Condensate (BEC), formed in a room-temperature Yttrium Iron Garnet (YIG) film by radio-frequency space-homogeneous magnetic field. The magnon BEC is prepared to have a well defined frequency and non-zero wavevector. We demonstrate how the crystalline "density" as well as the time and space textures of the resulting crystal may be tuned by varying the experimental parameters: external static magnetic field, temperature, thickness of the YIG film and power of the radio-frequency field. The proposed space-time crystals provide a new dimension for exploring dynamical phases of matter and can serve as a model nonlinear Floquet system, that brings in touch the rich fields of classical nonlinear waves, magnonics and periodically driven systems

    This paper deals with such layer of English vocabulary as neologisms. It defines the concept of neologisms, the main reasons for the emergence of new words, and indicates the sources in which they are contained, e.g. Cambridge Dictionary, Oxford English Dictionary, Macmillan Dictionary and Merriam-Webster Dictionary. The paper offers the detailed classification of neologisms based on the method of their formation and describes their features giving several examples for each type, e.g. phonological neologisms, borrowings and morphological neologisms, which are formed by affixation, composition, conversion and contraction. In addition, it draws attention to the problem of translating neologisms and the authors list various techniques of translating them, e.g. transcription, transliteration, calquing, and descriptive translation, each of which being characterized and accompanied by an example taken from one of the above sources. The paper is of great help and interest to students of philology, linguistics and other language specialties, novice and practicing translators, and anyone interested in languages and following their development.Π’ Π΄Π°Π½Π½ΠΎΠΉ ΡΡ‚Π°Ρ‚ΡŒΠ΅ рассматриваСтся Ρ‚Π°ΠΊΠΎΠΉ пласт английской лСксики, ΠΊΠ°ΠΊ Π½Π΅ΠΎΠ»ΠΎΠ³ΠΈΠ·ΠΌΡ‹.

    This article deals with the research in the field of quasi-realia of Β«The Lord of the RingsΒ», an epic novel created by the famous English writer, translator, linguist and philologist, John Ronald Reuel Tolkien. This article is devoted to the problem of analyzing different techniques of rendering two groups of onymic vocabulary – quasi-toponyms and quasi-anthroponyms. Taking five translations of the epic novel Β«The Lord of the RingsΒ» by J.R.R. Tolkien made by V.S. Muravyov and A.A. Kistyakovsky; A.A. Gruzberg; Z.A. Bobyr; V.E. Volkovsky, V. VosedΠΎy (pen-name of V.G. Tikhomirov) and D. Afinogenov (pen-name of K.M. Korolev); and V.V. Karrik and M.V. Kamenkovich, the most frequently used techniques of rendering quasi-toponyms and quasi-anthroponyms are identified, according to the classification of realias compiled by Bulgarian researchers S. Vlakhov and S. Florin. The article also shows the frequency of using certain techniques and identifies general tendencies and differences among the five above-mentioned translations regarding using the techniques of rendering quasi-anthroponyms and quasi-toponyms.Данная ΡΡ‚Π°Ρ‚ΡŒΡ посвящСна Ρ‚Π΅ΠΌΠ΅ изучСния пространства ΠΊΠ²Π°Π·ΠΈΡ€Π΅Π°Π»ΠΈΠΉ Ρ€ΠΎΠΌΠ°Π½Π°-эпопСи β€œΠ’Π»Π°ΡΡ‚Π΅Π»ΠΈΠ½ ΠšΠΎΠ»Π΅Ρ†β€, ΠΎΠΏΡƒΠ±Π»ΠΈΠΊΠΎΠ²Π°Π½Π½ΠΎΠ³ΠΎ Π² сСрСдинС пятидСсятых Π³ΠΎΠ΄ΠΎΠ² Π΄Π²Π°Π΄Ρ†Π°Ρ‚ΠΎΠ³ΠΎ Π²Π΅ΠΊΠ° ΠΏΠΎΠ΄ авторством извСстного английского писатСля, ΠΏΠ΅Ρ€Π΅Π²ΠΎΠ΄Ρ‡ΠΈΠΊΠ°, лингвиста ΠΈ Ρ„ΠΈΠ»ΠΎΠ»ΠΎΠ³Π° Π”ΠΆΠΎΠ½Π° Рональда Руэла Π’ΠΎΠ»ΠΊΠΈΠ½Π°.

    Long-distance supercurrent transport in a room-temperature Bose-Einstein magnon condensate

    Full text link
    The term supercurrent relates to a macroscopic dissipation-free collective motion of a quantum condensate and is commonly associated with such famous low-temperature phenomena as superconductivity and superfluidity. Another type of motion of quantum condensates is second sound - a wave of the density of a condensate. Recently, we reported on an enhanced decay of a parametrically induced Bose-Einstein condensate (BEC) of magnons caused by a supercurrent outflow of the BEC phase from the locally heated area of a room temperature magnetic film. Here, we present the direct experimental observation of a long-distance spin transport in such a system. The condensed magnons being pushed out from the potential well within the heated area form a density wave, which propagates through the BEC many hundreds of micrometers in the form of a specific second sound pulse - Bogoliubov waves - and is reflected from the sample edge. The discovery of the long distance supercurrent transport in the magnon BEC further advances the frontier of the physics of quasiparticles and allows for the application of related transport phenomena for low-loss data transfer in perspective magnon spintronics devices
