We study the effect of random potentials created by different types of impurities on the transverse magnetoresistance
of Weyl semimetals. We show that the magnetic field and temperature dependence of the
magnetoresistance is strongly affected by the type of impurity potential.We analyze in detail two limiting cases:
(i) the ultraquantum limit, when the applied magnetic field is so ...

We study the diffusive electron-electron interaction correction to conductivity by analyzing simultaneously ρxx and ρxy for disordered 2D electron systems in Si in a tilted magnetic field. Tilting the field is shown to be a straightforward tool to disentangle spin and orbital effects. In particular, by changing the tilt angle we prove experimentally that in ...

В работе исследовалась магнетопроводимость тонких пленок Bi2Se3 с защитным слоем Se, выра
щенных на подложках (111) BaF2. Наблюдаемая отрицательная магнетопроводимость в малых полях,
обусловленная эффектом слабой антилокализации, так же как и осцилляции Шубникова–де Гааза в
больших полях, определяется только перпендикулярной к плоскости пленки компонентой магнитного
поля. Полученные экспериментальные результаты могут быть разумно объяснены в предположении на
личия в исследуемых пленках ...

The longitudinal magnetoresistance of the array of parallel-oriented bismuth nanowires each 100 nm in diameter grown by electrochemical deposition in nanopores of an Al2O3 membrane has been studied in magnetic fields up to 14 T and at temperatures down to 0.3 K. The resistance increases with the field and reaches a broad maximum in fields ...

We report results of systematic measurements of charge transport properties of the 20.5-nm-wide HgTe-based quantum well in perpendicular magnetic field, performed under hydrostatic pressures up to 15.1 kbar. At ambient pressure, transport is well described by the two-band semiclassical model. In contrast, at elevated pressure, we observed nonmonotonic pressure dependence of resistivity at the “charge ...

By measuring magnetoresistance and the Hall effect in a classically moderate perpendicular magnetic field in a Si-MOSFET-type macroscopic antidot array, we found a nonlinear with field, temperature- and density-dependent Hall resistivity. We argue that this nonlinearity originates from low mobility shells of the antidots with a strong temperature dependence of the resistivity and suggest a ...

We report thermodynamic magnetization measurements of two-dimensional electrons in several highmobility
Si metal-oxide-semiconductor field-effect transistors. We provide evidence for an easily polarizable
electron state in a wide density range from insulating to deep into the metallic phase. The
temperature and magnetic field dependence of the magnetization is consistent with the formation of
large-spin droplets in the insulating phase. These ...

Изучено влияние магнитного поля на линейную и нелинейную проводимость квазиодномерного по- луметалла Вейля с волной зарядовой плотности (ВЗП) (TaSe4)2I. Продольное магнетосопротивление во всех известных режимах движения ВЗП (линейная проводимость, крип, скольжение, “сверхпрово- димость Фрелиха”) положительно и не превышает доли процента. Аналогичные магнетотранспортные измерения были выполнены в образцах, профилированных сфокусированными ионными пучками та- ким образом, что ...

We report preparation of nanoribbons (crossection ~ 250*25 nm2) by focused ion beam etching of single-crystalline Bi2Se3 and detailed measurements of their magnetoresistance at temperatures down to 4.2 K, magnetic field up to 9 T. In a magnetic field parallel to the axis of nanowire the magnetoresistance shows up oscillations. Surprisingly, the Fourier analysis shows ...

We experimentally investigate charge transport through a single planar junction between a Cd3As2 Dirac semimetal and a normal Au lead. For nonsuperconducting bulk Cd3As2 samples we observe non-Ohmic dV/dI(V ) curves, which strongly resemble standard Andreev reflection with a well-defined superconducting gap. Andreev-like behavior is demonstrated for Cd3As2 samples with different surface and contact preparation ...

We propose potential geometry for fabrication of the graphite sheets with atomically smooth edges. For such sheets with Bernal stacking, the electron-electron interaction and topology should cause sufficiently high density of states resulting in the high temperature of either spin ordering or superconducting pairing. ...

In this work, we have examined the radiation-induced synthetic chemistry occurring in an astrochemically important C2H2–CO system at the molecular level using a matrix isolation approach. The 1:1 C2H2···CO intermolecular complex of linear structure was obtained in the solid low-temperature (5 K) noble gas matrices by deposition of the C2H2/CO/Ng (Ng = Ar, Kr, Xe) gaseous mixtures and ...

In this work, we present for the first time the Lyman α intensities measured by Voyager 1/UVS in 2003–2014 (at 90–130 AU from the Sun). During this period Voyager 1 measured the Lyman α emission in the outer heliosphere at an almost fixed direction close to the upwind (i.e.“ toward the interstellar flow). The data show an unexpected behavior in 2003–2009: the ...

This paper presents an algorithm for processing the transmission spectra of whisperinggallery optical microcavities for use as a nanoparticle detector. The algorithm is based on the broadening of the microcavity resonance curve during precipitation of nanoparticles on the microcavity surface. Experimental results on the detection of particles are compared with Langmuir adsorption theory. The contribution ...

FeCo and FeNi alloyed nanowires (NW) were obtained by the matrix synthesis method: the effect of the
growth voltage and the effect of using a reference electrode were studied. It is shown that the composition of
FeNi nanowires strongly depends on the growth potential (with its increase, the bcc structure is changing into
fcc), and it is also ...

To date, a number of lantibiotics have been shown to use lipid II — a highly conserved peptidoglycan precursor in the cytoplasmic membrane of bacteria — as their molecular target. The α-component (Lchα) of the two-component lantibiotic lichenicidin (Lchα), previously isolated from the Bacillus licheniformis VK21 strain, seems to contain two putative lipid II binding ...

We study regularization scheme dependence of beta-function for sigma models with two-dimensional target space. Working within four-loop approximation, we conjecture the scheme in which the beta-function retains only two tensor structures up to certain terms containing zeta_3. Using this scheme, we provide explicit solutions to RG flow equation corresponding to Yang-Baxter- and lambda-deformed SU(2)/U(1) sigma ...

We present temperature dependences of the large and the small superconducting gaps measured directly by SnS-Andreev spectroscopy in various Fe-based superconductors and MgB2. The experimental L,S(T ) are wellfitted with a two-gap model based on Moskalenko and Suhl system of equations (supplemented with a BCS integral renormalization). From the fitting procedure, we estimate the key ...

Sequential state discrimination is a strategy for quantum state discrimination of a sender’s quantum
states when N receivers are separately located. In this report, we propose optical designs that can
perform sequential state discrimination of two coherent states. For this purpose, we consider not
only binary phase-shifting-key (BPSK) signals but also general coherent states, with arbitrary prior
probabilities. Since ...
