Numerous studies have provided compelling evidence that the probability distribution of avalanche sizes follows a power law, and that 1/f noise is present in the stochastic dynamics of landslides. We present a theoretical explanation of these phenomena within the framework of self-organized criticality theory, proposing a discrete-time model in the form of a sandpile cellular ...

A discrete-time model is presented for the self-organization of the X/Twitter social network to the edge of a phase transition, characterized by avalanche-like propagation of information in the network. The model is based on the analogy between the critical dynamics of the X social network and sandpile cellular automata with Manna rule on the Chung-Lu ...

Superconducting properties of metallic micro- and nanowires can be entirely different from those of bulk superconductors. Of particular interest is the nonequilibrium current-induced state of a quasi-one-dimensional superconducting channel. The most interesting phenomenon here is the stepped I–V characteristic, explained by a process known as phase slip center activation. If the origin of such step-like ...

Machine learning (ML) has become a powerful tool for accelerating the development of carbon-based supercapacitors;
however, most published models assume that a single predictive framework can describe both conventional
porous carbons and hybrid carbon electrodes. Here, we test this assumption using a comprehensive
benchmark dataset and an extended literature-curated dataset enriched with synthesis- and electrolyte-related
descriptors. Three ML algorithms ...

This paper compares the ranging precision of direct time-of-flight (dToF) and non-line-of-sight (NLOS) LiDAR architectures, both using a superconducting nanowire single-photon detector (SNSPD). Both systems operate at 1550 nm with a 50 ps pulsed laser and time-correlated single-photon counting (TCSPC). The dToF configuration achieved approximately 100 µm precision at 10 m, while the NLOS configuration achieved 500 µm precision for ...

Designing stable quantum computers with the ability to correct errors responsibly requires a detailed understanding of the physical processes that underlie these devices. In this study, detailed quantum mechanical simulations of the atomic structure, charge distribution of electron density, and distribution and orientation of magnetic and quantum states as a function of applied external pressure ...

Manufacturing precise quantum computers with small errors in quantum operations, long coherence times, and low power consumption is the most important challenge in modern nanoelectronics. To understand the operating modes of such calculators in detail, both the optimal arrangement of the qubit system within the structure and changes in its magnetic properties must be comprehensively ...

The single crystals of the layered organic conductor κ-BEDT-TTF₂Cu₂(CN)₃ were studied by X-ray diffraction and X-ray photoemission spectroscopy. The electronic structure of the conducting BEDT-TTF₂ layer and its Fermi surface details were analyzed by quantum chemical calculations within the DFT level theory based on structure model of the isolated positively charged conducting layers in a ...

The magnetic doping of Dirac semimetals breaks their time-reversal symmetry thus giving rise to anomalous
transport phenomena promising for applications. While the Dirac cone (DC) manifestations were observed in the
electron transport of (Cd1 xCrx)3As2 alloys up to x = 0.06, their mechanism remains challenging. To address this
challenge, we performed DFT calculations of the (Cd0.96Cr0.04)3As2 alloy with ...

The stability of the dumbbell structure has been confirmed by previous theory and experiment. Based on first-principles calculations, we proposed hexagonal dumbbell graphene (HDB C10) and rectangular dumbbell graphene (RDB C10) monolayers containing periodically raised C (CR) atoms. They turn out to have high mobility semiconductor properties. By adsorbing H atoms on these CR atoms, ...

В данной работе мы представляем результаты экспериментального
исследования времени сбоя фазы волновой функции электрона в ультратонких
сверхпроводящих плeнках ниобия (Nb). В Nb пленках, пассированных слоем кремния
(Si), наблюдается сильная зависимость времени сбоя фазы от температуры τϕ ~ Т^(-2.5),
вероятно, обусловленная электрон-фононным рассеянием. Однако в непокрытых
кремнием Nb пленках наблюдается насыщение времени сбоя фазы при низких
температурах, что может быть обусловлено наличием ...

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 ...

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 ...

X-radiolysis of the noble-gas matrices containing both H2O and CO was investigated at 5 K using infrared spectroscopy. It was found that formic acid molecule (HCOOH) could be produced from the matrix-isolated H2O⋯CO complexes, either directly as a result of irradiation or upon the subsequent annealing activating the trans-HOCO + H reaction. The former way was ...

Investigations of the low-temperature radiation-induced transformations in the C2H2–H2O system are relevant to the chemistry occurring in interstellar and cometary ices. In this work, we applied a matrix isolation technique to study the radiation-driven evolution of this system at molecular level in order to get new mechanistic insight. The 1:1 C2H2⋅ ⋅ ⋅H2O complexes were prepared in ...

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 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 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 ...

Although it has been demonstrated that the SiGe HBTs can achieve faster unloaded circuit speed at cryogenic temperature than at room temperature, modelling of the SiGe HBTs at low temperature has been limited. It is known that the standard SPICE models of bipolar transistor are effective and guarantee the valid results only up to a ...
