Квантовая динамика заряда в квазиодномерных сверхпроводниках

We derive the stress tensor of a flexible polymer solution within the Gaussian-chain self-consistent field theory (SCFT) without invoking the ground-state dominance (GSD) approximation. Starting from a covariant formulation of the single-chain partition function in a background metric, we obtain the symmetric stress tensor expressed through the full Edwards propagators. The result contains the local ...

Metastability of lipid vesicle shapes in uniaxial extensional flow

Pikina E., Physical Review E - Statistical, Nonlinear, and Soft Matter Physics 2026 Vol. 113 No. 5

In this work, we investigate the elastic properties of deflated vesicles and their shape dynamics in uniaxial extensional flow. By analyzing the Helfrich bending energy and viscous flow stresses in the limit of highly elongated shapes, we demonstrate that all stable vesicle configurations are metastable. For vesicles with small reduced volume, we identify the type ...

During this time, about 1,000 cases of hectometric continuum (HMC) radiation in near‐Earth space were detected, which made it possible to identify characteristic features on different time scales. On a daily scale, it was established that HMC is ...

On the nature of hectometric continuum-type emissions in the near-Earth plasma

Mogilevsky M. M., Shaposhnikov V., Chernyshov A. et al., Physics of Plasmas 2025 Vol. 32 P. 1–10

The ERG (Arase) satellite recently discovered a non-thermal hectometric continuum with a narrowband frequency structure. The mechanism behind the generation of this type of emission in the near-Earth plasma is still unknown.

(111)-Textured p-Type PbTe Films Grown on Muscovite Micawith High Room-Temperature Hole Mobility

Kobtsev Danil, Albert J., Nitzan M. et al., Applied Sciences (Switzerland) 2026 Vol. 16 No. 17 Article 8577

AIVBVI semiconductors, particularly lead chalcogenides, remain key materials for mid-wave infrared (MWIR) photodetection due to their narrow bandgap and exceptional carrier transport properties. However, the realization of high-quality p-type PbTe thin films, suitable for p–n junction devices, remains a technological challenge. In this work, we report the fabrication of high-mobility p-type PbTe thin films grown on ...

Pyramidal solitons: existence, instability, and interactions

Melnikov I., Pelinovsky E., Nonlinear Dynamics 2026 No. 114 Article 934

Pyramidal solitons (solitons with more than two inflection points) of the generalized Korteweg–de Vries (KdV) equation are investigated. Necessary and sufficient conditions for the existence of such structures are presented. Within the framework of the generalized Gardner equation — the simplest model that admits pyramidal solitons as solutions — it is shown that these solutions ...

Robust CsPbBr3@SiO2 Nanocrystals with Controlled Shell Growth for Stable High-Resolution X‑ray Scintillation Imaging

Zhukov A., Liang Y., Zhang X. et al., ACS Applied Nano Materials 2026 Vol. 9 No. 32 P. 15224–15232

The development of high-light-yield scintillators based on perovskite quantum dots (PQDs) is hindered by their intrinsic instability and aggregation, which severely limits their long-term operational reliability and integration into polymeric matrices. Silica coating has been demonstrated as an effective strategy to enhance the stability of PQDs. However, achieving fast and uniform silica encapsulation on individual ...

Non-epitaxial perovskite polariton laser diode operating under direct current

Zhukov A., Kryzhanovskaya N., Moiseev E. et al., Nature 2026 Vol. 656 P. 80–85

Reaching lasing in electrically pumped microdevices based on solution-processed semiconductors poses a substantial scientific and technological challenge. Halide perovskites offer a promising platform for electrical injection1, as their optically excited single-crystal cavities2–4 and predesigned5,6 or postprocessed microstructures7,8 have exhibited low lasing threshold. Indirect electrical pumping of a dual-cavity perovskite laser was recently obtained9, using a well-established technological concept of embedding a ...

Understanding the electric double layer at electrode–electrolyte interfaces, Part III: crystallographic-face dependence of silver capacitance in aqueous NaF solutions

Mazur D., Brandyshev P., Doronin S. V. et al., Electrochimica Acta 2026 Vol. 577 Article 149729

The electric double layer (EDL) at a single-crystal metal surface is controlled not only by the electrolyte composition and the electrode potential, but also by the atomic structure of the surface itself. This makes the Ag(hkl)/NaF interface a stringent test for continuum theories of the EDL. In the third part of our series, we examine ...
