'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.

Coexistence of the magnetically ordered and Haldane states in (Y1-xNdx)2BaNiO5

Ch. 03003. P. 1–4.
Popova E., Klimin S. A., Popova M. N., Klingeler R., Büchner B., Vasiliev A. N.

The magnetic properties of (Y1-xNdx)2BaNiO5  with x = 0.01, 0.02, 0.03, 0.04, and 0.05 are investigated by means of specific heat, magnetic susceptibility, and spectroscopic measurements. We estimate a magnetic contribution of the neodymium subsystem into the magnetic susceptibility and specific heat using temperature dependencies of the splitting of the ground Kramers doublet of the Nd3+ ion obtained from spectroscopic experiments. We estimate also the contribution caused by nickel chain breaks and by ferrons. Different scenarios of low-temperature magnetic behavior is discussed.

The main motif of the crystal structure of rare earth nickelates (Y1-xRx)2BaNiO5 (R = Gd or Nd) are chains of Ni2+ ions with spin S=1 (Haldane chains) directed along the a axis of the crystal. The interaction between rare earth ions R3+ located between the chains is carried out through spin fluctuations of the nickel ...

The compounds of the (Y1-xNdx)2BaNiO5 family contain two types of magnetic ions: Ni2+ (S=1) and Nd3+ (J=9/2). The interaction between the magnetic subsystems of the studied compounds with different concentrations of neodymium is manifested in anomalies in the temperature dependence of the heat capacity C(T) and the magnetic susceptibility χ(T). The paper analyzes experimental data ...

In the compounds of the (Y1-xNdx)2BaNiO5 family, the paradoxical coexistence of the Haldane phase and spin waves is realized. The magnetic ordering in the system is caused by the interaction of Nd3+ ions through spin fluctuations of a nickel chain, which remains internally disordered. Nd3+ magnetic moments do not deviate from the c axis of ...

In a number of quasi-one-dimensional magnets, transition metal ions obeying the motives of the crystal lattice can form chains of integer spins that are distant from each other, named Haldane chains. This paper provides a brief overview of the magnetic properties of Haldane chains and considers some compounds containing such chains. The main features of ...
