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 ...

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 magnetoresistance of superconductor–topological insulator–superconductor structures, with indium as the superconductor and TaSe3 as the topological insulator, shows steplike features on the resistance under magnetic fields. These resistance steps result from the suppression of superconductivity, induced by the superconducting proximity effect in both the bulk and surface states of the topological insulator. The position and ...

We report on the low temperature measurements of the magnetotransport in Si-doped InAs quantum wire in the presence of a charged tip of an atomic force microscope serving as a mobile gate, i.e. scanning gate microscopy (SGM). By altering the carrier concentration with back gate voltage, we transfer the wire through several transport regimes: from ...

В книге затронут широкий круг вопросов физики ограниченных твёрдых тел. Рассмотрено взаимодействие электромагнитного излучения рентгеновского диапазона, «тепловых» нейтронов и электронов с поверхностью твёрдого тела и многослойными структурами. Излагаются основы теории электронных состояний в полуограниченных твёрдых телах и применение метода туннельной спектроскопии для экспериментального изучения этих состояний. Возникновение поверхностной (прикраевой) сверхпроводимости на границах раздела рассматривается как ...

We consider an interferometer based on artificially induced topological superconductivity and chiral one-dimensional (1D) Majorana fermions. The (nontopological) superconducting island inducing the superconducting correlations in the topological substrate is assumed to be floating. This allows probing the physics of interfering Majorana modes via microwave response, i.e., the frequency-dependent impedance between the island and the earth. ...

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 ...

Синтезирован новый политип NbS3-квазиодномерного проводника с высокотемпературными волна- ми зарядовой плотности (ВЗП). Исследования в просвечивающий электронный микроскоп (ПЭМ) при комнатной температуре показали, что из двух сверхструктур, существующих в изученной ранее моно- клинной фазе, наблюдается лишь одна, с периодом вдоль цепочек, близким к (1/0.352)b. Помимо этого, наблюдается новое несоизмеримое искажение решетки с периодом, близким к 2b. Транспортные свой- ...

We report on high temperature (T) studies of conductivity, s, of the monoclinic phase of NbS3 (NbS3-II). The compound is shown to be stable up to T~550 K. Threshold non-linear conductivity and Shapiro steps on the I e V curves can be seen up to TP0 z 450 e 475 K clearly demonstrating sliding of a charge- density wave (CDW). The feature in s(T) shows that TP0 is ...

We consider the nanoscale electronic phase separation in a wide class of different materials, mostly in strongly correlated electron systems. The phase separation turns out to be quite ubiquitous manifesting itself in different situations, where the itineracy of charge carriers competes with their tendency toward localization. The latter is often related to some specific type of magnetic ordering, e.g. antiferromagnetic in manganites and ...

The crystal structure of the Sb (111) surface is studied in the density functional theory approximation. It is shown that as a result of the rupture of double atomic layers on the surface, a defect near-surface region 6–8 atomic layers thick is formed, similar to a topological soliton in one-dimensional hydrocarbon chains.
