Predicting multi-component oil viscosity using machine learning methods

Deshchenya V., Nikolay D. Kondratyuk, Sivakova A. et al., Chemical Engineering Sciences 2027 Vol. 337 Article 124616

Accurate prediction of complex formulation viscosity is crucial for the lubricant industry and engineering processes. However, developing generalizable models remains challenging due to the complexity of industrial mixtures and the scarcity of public experimental data, often resulting from corporate proprietary restrictions. This study presents a machine-learning workflow for viscosity estimation from a proprietary pseudonymized dataset, ...

Zubov A., Zubov A., Малявко, Я. et al., Computer Physics Communications 2025 Vol. 317 Article 109860

The concept of representative volume (REV, or RVE in material sciences) is the cornerstone of continuum scale models – one needs to get the volume big enough so that it could be represented with an averaged value (scalar, vector or tensorial, etc.). While REV should be established in all larger scale simulations, this is rarely ...

Low-energy collective excitations in a gold monolayer, Vyacheslav Silkin and Maxim Kagan Working papers by Cornell University Series cond-mat other “arxiv org” 2610. 31805 22 Oct. 2026

Kagan M., / Series Series "arxiv org" 2610.31805 "cond-mat other "arxiv org" 2610.31805". 2026. No. 2610.31805.

Abstract The low-energy plasmonic properties of a free-standing Au (111) monolayer, frequently referred to as goldene, are investigated by time-dependent density functional theory in the random phase approximation. In the evaluation of dielectric and loss functions, the first-principle, band structure characterized by a single s − p energy band at the Fermi level is taken ...

From frozen Coulomb decoherence to thermalization: Classical and quantum density-matrix routes to Balescu–Lenard and Landau kinetics

Budkov Y., Annals of Physics 2026 Vol. 495 No. 3 Article 170796

We study the density-matrix kinetics of a charged test particle in two types of Coulomb environment. For a prescribed Gaussian potential, averaging the random-unitary dynamics leads to a Born–Novikov memory equation; Novikov’s identity is exact, but its closure requires a second-order approximation. An equilibrium quantum bath instead yields a Born–Redfield equation with ordered correlators and ...

On non-Abelian waves repeatedly changing sign at constant phases

Alexander S. Rabinowitch, International Journal of Modern Physics A 2026 Vol. 41 No. 30 Article 2650168

In this paper, we study a new class of wave solutions to the SU(2) Yang-Mills equations in the region outside field sources. They represent a significant addition to the wave solutions obtained in our previous publications describing non-Abelian transverse progressive waves propagating in the direction of the Cartesian z-axis. In the new paper, wave solutions to the considered system ...

Electrically driven Rabi dynamics of magnetic field induced corner states in a two-dimensional topological insulator

D.V. Khomitsky, Lavrukhina E. A., Krasavin D. P. et al., Physical Review B: Condensed Matter and Materials Physics 2026 Vol. 114 No. 22 Article 225414

We study coherent electric manipulation of magnetic field induced localized states at a double kink of a helical edge in a HgTe/CdHgTe quantum well. An in-plane magnetic field opens a gap in the one-dimensional (1D) edge spectrum, while changes in the edge orientation generate localized in-gap states at the kinks. We show that, for suitable ...

Stress tensor in fundamental measure theory of hard-sphere fluids: A thermomechanical approach

Budkov Y., Kalikin N., Journal of Chemical Physics 2026 Vol. 165 No. 16 Article 164108

We derive the local pressure tensor generated by the original Rosenfeld fundamental measure theory (FMT) for hard-sphere fluids from an arbitrary infinitesimal deformation. The variation of a finite-distance FMT kernel is written via the line integrals of the local deformation gradient along the straight segment connecting its end points. The resulting symmetric pressure tensor consists ...

Отсутствие отражения фонон-поляритона от края металлической маски на поверхности SiC

Ивченко В. С., Иевлева В. А., Matienko D. et al., Журнал технической физики 2026 № 9 С. 1738–1749

Задача о возбуждении бегущих фонон-поляритонных волн на поверхности полярного кристалла падающей извне световой волной (с частотой, близкой к частоте решеточных колебаний) решена теоретически только для бесконечной открытой поверхности кристалла. В случаях, когда часть поверхности покрыта металлической маской, препятствующей проникновению возбуждающего излучения к атомам среды, и эта маска имеет произвольную форму, общепризнанного решения неоднородной задачи нет. ...

Dissipative quantum mechanics of Andreev bound states

Zaikin A., Kalenkov M. S., Physical Review B: Condensed Matter and Materials Physics 2026 Vol. 114 Article 214502

We propose a microscopic scheme that allows to describe ac Josephson effect in superconducting junctions in terms of dissipative quantum dynamics of subgap Andreev bound states. This approach is particularly useful for highly transparent junctions at subgap bias voltages in which case a nontrivial combination of Landau-Zener tunneling between Andreev levels and their instability due to quasiparticle escape ...

Landau-Zener Tunneling and Quantum Interference of Andreev States

Zaikin A., Kalenkov M. S., Physical Review Letters 2026 Vol. 137 Article 076004

With the aid of a microscopic theory we derive an effective Hamiltonian that controls quantum dynamics of Andreev states in superconducting nanojunctions out of equilibrium. Resolving the corresponding Schrödinger-like equation we obtain the “wave functions” for Andreev levels and evaluate electric current across the junction in the presence of an external voltage bias.We demonstrate that quantum interference of Andreev ...

Ground state geometry of PPV oligomers

Conformational space of polyphenylenevinylene oligomers is systematically investigated computationally at energies relevant for room temperature dynamics in a solvent and in a solid state. Our calculations show that optimal oligomer structures are essentially planar. However, lack of a deep minimum at the planar geometry allows for large molecular deformations even at very low temperatures. At ...

Исследованы магнитные свойства слоевых нанопроволок (НП), состоящих из чередующихся слоев никеля и меди. В таких структурах магнитные свойства определяются несколькими факторами – аспектным отношением ферромагнитых слоев, дипольным взаимодействием между соседними слоями внутри одной НП, а также взаимодействием соседних НП. Массивы НП были получены методом матричного синтеза. Слои никеля имели фиксированную толщину 400 нм, толщину слоев меди варьировали от 25 ...
