'Cultural Studies Seeks to Understand What Lies Beneath the Surface of Everyday Things'
Maxim Zhiganov has been exploring different aspects of sound for many years—first in relation to his native Perm and then on a broader, global scale. In this interview for the HSE Young Scientists project, he talks about sound maps, the special issue of the journal Logos, and why it is important to make the familiar less clear and obvious.

At HSE University–St Petersburg, Experts Discuss How AI Changes Tourist Routes and Cultural Heritage
Neural networks are no longer simple travel assistants; now they decide what to include on the route and what to skip. Artificial intelligence changes how people perceive a place and shapes the image of tourist centres. At the II International Scientific and Practical Conference ’Information Technologies in the Preservation and Promotion of Cultural Heritage,’ researchers discussed who controls algorithmic solutions and in what ways, and whether authentic traditions get lost in them.

Road Injuries Leading Cause of Death Among Men Aged 10 to 39
Worldwide, road injuries are the leading cause of death among males aged 10–39. An international team of researchers reached this conclusion as part of the Global Burden of Disease Study 2023, analysing data from 204 countries between 1990 and 2023. Their findings have been published in The Lancet Public Health, with HSE University Professor Vasily Vlassov listed among the collaborators.

Financial markets’ deterministic aspects modeled by a low-dimensional equation

Scientific Reports. 2022. Vol. 12. Article 1693.
Orlando G., Ruedi S., Bufalo M.

We ask whether empirical finance market data (Financial Stress Index, swap and equity, emerging
and developed, corporate and government, short and long maturity), with their recently observed
alternations between calm periods and financial turmoil, could be described by a low‑dimensional
deterministic model, or whether this requests a stochastic approach. We find that a deterministic
model performs at least as well as one of the best stochastic models, but may offer additional insight
into the essential mechanisms that drive financial markets.

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 ...

This article challenges the prevailing view that customer experience in online retail is shaped primarily at the digital interface. Instead, the authors investigate whether physical, interpersonal service encounters at third-party pickup points carry greater weight. Using the partial least squares structural equation modeling to evaluate 18,023 marketplace customers, they analyzed five sequential journey stages to ...

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 ...

Weakly non-integrable solitary wave collisions in the modified Benjamin–Bona–Mahony equation
Flamarion M. V., Pelinovsky E., Wave Motion 2027 Vol. 148 Article 103867
We consider the interaction of two solitary waves in the modified Benjamin–Bona–Mahony (mBBM) equation in a regime where a small parameter measures the departure from the classical modified Korteweg–de Vries (mKdV) equation. A regular perturbation method is used to analyze the modification of the two-soliton wave field induced by the weak non-integrability of the mBBM equation. We show that, ...

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 ...

Применение специальных финансово-экономических знаний в антимонопольных делах о картелях
Москвитин О. А., Финансовые рынки и банки 2026 № 9 С. 730–732
Статья посвящена проблеме применения специальных финансово-экономических знаний при рассмотрении дел о картельных соглашениях. Автор исходит из того, что российская правоприменительная практика по делам о картелях исторически опирается преимущественно на поведенческие и цифровые «следы» сговора, тогда как экономический анализ зачастую играет вспомогательную роль. На основе анализа отечественного и зарубежного опыта обосновывается тезис о необходимости разграничения двух ...

Happiness and entrepreneurship: investigating the link between subjective well-being and entrepreneurial intention among student
Kulagina E., Slykhova K., Lechenko E. et al., BRICS Journal of Economics 2026 Vol. 7 No. 4 P. 1–46
This study explores the relationship between subjective well-being (SWB) and entrepreneurial intention (EI) among university students in Russia, where entrepreneurial engagement remains relatively low. It emphasizes the role of internal psychological drivers, such as SWB, willingness to take risks and entrepreneurial self-efficacy, rather than focusing solely on external factors. Drawing on the Theory of Planned ...

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. ...

Early Career Gender Wage Gap in STEM: New Evidence from Administrative Data
Ksenia V. Rozhkova, Sergey Yu. Roshchin, Natalya K. Yemelina, Population and Economics 2026 Vol. 10 No. 3 P. 61–81
Increasing female representation in technical majors, traditionally associated with high earnings, is recognised as a mechanism for promoting gender equality in the labour market. However, if women quit STEM soon after graduation, increasing their proportion in relevant disciplines will not help reduce the gender wage gap. This paper provides new evidence of the ‘leaky pipeline’ ...
