Universe is hotter than expected
Researchers at the UNIGE have succeeded in reconciling cosmological theory and observations of the Universe by considering that it is hotter than previously thought.

Astrophysicists still encounter various inconsistencies between cosmological theory and measurements made with various research instruments. Four values are particularly problematic: the speed of the expansion of the Universe today, the magnitude of matter density variations within the Universe, and the temperature variations and trajectory of the primordial light of the Universe. By no longer fixing the temperature of this light and the curvature of the Universe in their calculations, researchers at the University of Geneva (UNIGE), Switzerland, have succeeded in reconciling theory with the data. The reason? We live in an under-dense region in the Universe which slightly distorts the calculations an

A NUST MISIS professor was part of an international research team that has found evidence for the existence of the Zeeman spin-orbit coupling in antiferromagnetic conductors. This work may pave the way for the next generation of electronics. The study was published in
npj Quantum Materials.
The electron possesses two fundamental properties: charge and spin. Conventional electronic devices use only the charge of electron for information processing. In recent years, an enormous research effort has been focused on building fundamentally new electronic devices (often called spintronic devices ) that would specifically exploit spin properties in addition to charge degrees of freedom. Transfer from conventional electronics to spintronics technology opens the possibilities to construct devices with high storage density and fast operation. The two-component nature of spin-based systems makes them potentially applicable for quantum computing.
